Updating the number of processors on Linux390
If the total number of processors or shared processors in your environment 
changes, you need to update this information for all agents influenced by 
this change. Otherwise, the system will display wrong information.

You also have to tell it what kind of engine (z9, z10, etc).  Jeesh.

If you have to do all this manual work, why not manually tell IBM how many 
licenses you have instead?  It's probably easier and less error-prone.

Separate virtual switch controllers

[O'Brien, Dennis L]

We are working on a project to provide Internet access to select Linux guests 
on z/VM.  The network team plans to use separate OSA's and virtual switches for 
this.  For the initial testing, there will be one OSA and virtual switch for 
the presentation zone and a separate OSA and virtual switch for the secure 
zone.  These are in addition to the existing virtual switch that we already 
have on our internal network.  The network people have also asked for separate 
virtual switch controllers.  Is there any reason to create separate controller 
virtual machines (DTCVSWx) for these virtual switches?  My understanding is 
that no data flows through the controllers.  They're just used to manage the 
virtual switches.  I believe there was a statement from IBM that the two 
default controllers, DTCVSW1 and DTCVSW2, are sufficient for any number of 
virtual switches.  Is there any security risk if the same controllers manage 
virtual switches for multiple zones?

We have CBDIODSP and HCM all set up and configured so the z/OS guys
COULD use the VM-based HCM to build their files.  I'm just still unclear
how CP picks up the changes in the new IOCDS and makes them available

Hi Folks,

 

For many (many) years, when it comes to managing the IOCDS I  simply
hand-create an IOCP file, use IOCP with WRTAx to store it, and do a POR
to load it.  If the changes are needed immediately, I use CP commands to
manually define the new hardware.

 

Our z/OS guys want to manage the IOCDS and be able to dynamically
activate an entirely new IODF file (created either on their system or
using VM's HCM/HCD).  I'm unclear as to when/how the changed IODF file
becomes dynamically available to the running z/VM system.  Let's say I
store the new IODF using IOCP with WRTAx to store it, and then execute
SET IOCDS_Active to mark it as the active IOCDS - according to the doc
for SET IOCDS_Active this simply marks the IOCDS as active for the NEXT
POR (and write-protects it) - but it doesn't look like the changes in
the new IOCDS are reflected to the running z/VM system until a POR
occurs.

 

What am I missing here?  Is it even possible to store a new IOCDS, mark
it as active for the next POR AND have CP add/change/delete IO
definitions by comparing the prior IOCDS with the newly activated one?

Does anyone have access to the source for such a program (that can be

Re: 2nd level z/VM 5.4 installation

[O'Brien, Dennis L]

Sherry,
Instead of installing direct from an FTP server, you can put the files on a VM 
minidisk and install from there.  To do that, the minidisk must have at least 
4500 cylinders.

Back when DVD installation was first introduced (z/VM 5.1.0, I think), we only 
had 3390-3 disks on VM, so I tried installing from SFS.  It mostly worked.  The 
install would run out of memory periodically, but I could restart it and it 
would pick up where it left off.  IBM's answer was that installation from SFS 
wasn't supported.  I don't know if they fixed the memory leak in a subsequent 
release.

Re: 2nd level z/VM 5.4 installation

[O'Brien, Dennis L]

Sherry,
Note that what I was referring to in my previous note and what Alan describes 
below are not the same thing.  You can do what Alan described, using the VM FTP 
server to serve the files.  You can also install from a VM minidisk without 
using any FTP server.  You can get the files on the minidisk by putting the DVD 
in your PC and using your terminal emulator to upload the files.  If you do 
that, it needs to be a 4500-cylinder minidisk.

That is a bit confusing, isn't it?  It means that if you want to do an FTP 
install (annoyingly, yet understandably, documented as a subset of the DVD 
install) AND you want to use the VM FTP server, THEN you will need the 
equivalent of 4500 cylinders to contain the contents of the DVD.  If 
you're actually installing from some other FTP server, then you follow the 
3GB guideline.

Of course, you can always use SFS to hold the DVD contents (not a DVD .iso 
image!) since it aggregates multiple minidisks into a single filepool. 
Follow the instructions for uploading the DVD contents via FTP, but CD 
VMSYSU:MAINT.VM54  (for example, assuming you have done all the SFS admin 
things needed to make that happen.)

It's often hard to ferret out whether DVD refers to the physical media, 
the DVD contents, or the HMC Load from DVD/FTP-related functions.  But 
it's easy once you know how!  :-)

Re: 2nd level z/VM 5.4 installation

[O'Brien, Dennis L]

Sherry,
The only way to get 4500 cylinders from a 3390-3 is to put two of them in an 
SFS filepool.  If you already have this set up, then the rest is relatively 
easy.  You can use the VM minidisk install method with minor changes.  Upload 
the files to SFS with your terminal emulator, then follow the directions for VM 
minidisk install.  When you're told to access the minidisk, access the SFS 
directory instead.  If the process runs out of memory and abends, IPL CMS and 
re-run the command that failed.  It will restart from a checkpoint and keep 
going.  Eventually, you'll get to the end.

I'm in the process of migrating our production LPARs from a z9 to a z10 and
I've found a bit of weirdness.  Since the z10 has been around awhile, I
assume this isn't anything new, but I wonder why it is happening.

I've found that a CMS minidisk that is created while on the z9, is readable
by a VM system on the z10.  However, if (from the z10) a fle is modified,
that file is no longer readable by the CMS system on the z9.
I get a DMSXIN104S error
code 3 when trying to read the file.  Moreover, if (from the z9), I try to
write a new file to the disk, I get a different error, and CMS crashes.
(All of these z/VM systems are the same by the way, z/VM 5.4.0 RSU 1001.)

I've always been able to share disks between systems on different processors
before, so I wonder what is different now?  I've got a z990 that I still
have to maintain and this is going to make life more difficult.

Re: General CMS minidisks and SFS on PAV DASD?

[O'Brien, Dennis L]

Mike,
We use PAV for volumes containing CMS minidisks.  We turned it on a few months 
ago on a system that we acquired with our last merger, and the user was quite 
pleased.  It took a couple of hours off of their nightly batch.  PAV is also on 
for volumes that contain SFS minidisks.  It doesn't help for volumes that have 
SFS data minidisks (storage group 2+), because those are full packs, but it 
doesn't seem to hurt anything.  Our catalog and log disks are a couple hundred 
cylinders each, and there are other CMS minidisks on those volumes.  I presume 
we're getting some benefit there.

Subject: [IBMVM] General CMS minidisks and SFS on PAV DASD?

We've always avoided using PAV volumes for general user (non-fullpack) CMS 
minidisks.  Instead we've only used DASD defined as 3390-3 so that I/O 
queueing is minimized.  That choice was in part due to management 
decisions.

Over the past weekend we needed to move some z/VM DASD quickly -- and the 
target DASD was already defined as PAV DASD.

The z/VM CP Planning and Administration manual clearly states that z/VM 
Paging and SPOOLing operations do not take advantage of PAV. (no argument 
here).  We'll still plan to keep page and SPOOL volumes on non-PAV 3390-3 
DASD.

But the same manual also states that When multiple CMS volumes are 
defined on a real PAV volume, I/O operations by CMS can be concurrently 
scheduled on any real PAV base or alias subchannel by z/VM.  The CMS user 
does not need to take any action for this to occur.

Well, that's book larn'in.   Can anyone provide real-life results of 
using PAV volumes for general-purpose CMS user minidisks, and... for SFS 
filespaces?

Do you see real I/O improvement for those apps?  If so, the next time 
we're asked we might recommend larger 3390 volumes, mod 9's or 27's 
(depending on the number of available paths) to permit larger minidisks 
without SFS overhead, and improved SFS performance.

z9 clock speed

[O'Brien, Dennis L]

A question came up today about the clock speed of the various System z models.  
The context is some application software that's licensed by the speed of the 
CPU.  Apparently, there's a big price difference (measured in millions) if the 
speed is over 1.5 GHz or so.  I dug around on IBM's web site and found that 
z10's have a clock speed of 4.3 GHz and z196's have a clock speed of 5.2 GHz.  
I was unable to find the speed of a z9.  I recall from the z10 announcement 
that the z10 had a major increase in speed.  I'm thinking that the z9 was under 
2 GHz.  Does anyone know the speed of the z9, or where I can find that 
information?  The glossy announcements of the z10 on IBM's web site have been 
replaced by glossy announcements of the z196.  If it makes a difference, I'm 
interested in z9 EC, not BC.

For this purpose, relative overall performance doesn't matter.  The software 
price is based on the speed of the chip.  If the price is also based on the 
number of CPU's, then any savings on the slower speed might be offset by costs 
for more CPU's.  First, we need to know the speed.

Re: Vswitch Grant as a CMD in User's Directory?

[O'Brien, Dennis L]

You would HAVE to buy an ESM, whether from IBM or CA.

Or have IBM include a basic awful one (eg, RACF) in the price of VM and be
done with it. Including a basic one that can be replaced with Something
Else would make everybody (IMHO) happy. The internal cost of including
RACF can't be that large.

From posts I've seen in the past, I don't think IBM can include a free ESM.  
They're not allowed to damage a competitor's business by making something free 
(i.e. no-charge feature) that they currently charge for.  If they make RACF 
free, that could put a big dent in CA's ESM business.  IBM can compete by 
trying to make RACF better than the CA products, but they can't just make it 
free.

If IBM requires an ESM to run z/VM, customers will be required to pay for it.  
Be careful what you wish for.

Re: BRP

[O'Brien, Dennis L]

Richard,

We're using disk replication on HDS DASD for disaster recovery.  We were
able to reduce a script that had about 30 steps to one that isn't much
more complicated than:

1.   Suspend replication

2.   IPL

3.   Answer one question: is this a test or a real disaster?

4.   Certify

 

The test or real disaster answer determines the network configuration.
DR tests are behind a firewall, so they use different OSA's than we
would use for a real disaster.  The answer can also be used for other
things, such as determining which guests are started.  We don't start
z/Linux guests automatically during DR tests, because our Linux security
product has a problem with two guests having the same name.  If the DR
guest refreshes keys or whatever it does with Active Directory, the
production guest loses access.  This seems to happen around midnight, so
we start up DR guests when we're ready to test and shut them down as
soon as we're done.  One of our Linux people could explain this much
better than I can.

 

Make sure that your CP maintenance is current.  We had a CP abend and
guest I/O errors when we resumed replication on a z/VM 5.4.0 RSU 0801 or
0802 (I forget which) system.  The problem went away when we upgraded to
RSU 1001 plus some additional service.

 

We have two copies of the disks in our DR site.  This allows us to
continue replicating production on the secondary disks while we test on
the tertiary disks.

Finally, the powers that be are considering remote shadowing of DASD as
the way to handle the BRP situation. The time we are allotted to recover
the system has been reduced to a number that is impossible using tape
backups. I would appreciate it if anyone who is already doing this would
regale me of their experiences - what they are doing, what are the
gotchas, how satisfied are they, etc.

 

It undoubtedly is different depending on the dasd vendors so here is
what we have: 

 

* EMC DASD - about half of our DASD.

* HDS DASD - the other half.

* Currently, there is no SCSI, it is all ECKD

 

We currently have no IBM DASD; however, that does not mean that we will
not have some in the future. Every couple of years, we go through a DASD
refresh, at which time we may change vendors.

 

I will gladly accept replies on or off list. TIA.

Re: Copying SFS filespaces from one pool to another

[O'Brien, Dennis L]

A filepool administrator can create aliases on behalf of any user.  The syntax 
is the same as the general user command.  The major restriction on aliases is 
that they can't cross filepools.  If you move one user to a new pool, he can't 
have aliases in the new pool pointing to base files in the old one, or vice 
versa.

Yes (there's actually a command to do it now: FILEPOOL RENAME), but then you
lose all the authorizations and aliases, and apparently you can't use the
CMS RELOCATE command to move a directory between two filespaces, even in the
same filepool -- or at least I can't construct the right command line for it
to work. There's also no admin version of CREATE ALIAS to create an alias on
behalf of a user, so you can't restore aliases in the new filepool after
you've relocated the files. You can't use CP FOR, because SFS isn't a CP
thing, and short of autologging the user and driving the whole process via
SCIF (thus producing a billable event and a lot of CPU and I/O charged to
the user), there's no way short of scheduling a hands-on session with each
user and a big set of credits to their bills to make this work.

Oh, and by the way, none of the FILEPOOL commands can be used in CMSBATCH,
so you get to leave a privileged id logged in some where for however long it
takes to run the move process. Just to make the process more fun. Grr.

The SFSTOOLS package has a COPYUSER EXEC that Scott Nettleship wrote that
seems to be a pretty good base for starting into writing my own tool. I'll
just modify that -- at least I won't be completely starting from scratch.

What a PITA. Clearly I need to add porting rsync to CMS to my list of things
to be done if IBM is going to continue to impose more SFS/BFS stuff on us.

On first level, define one Virtual CTC (FCTC, SCTC) into TCPIP (or
another capable machine) to connect to second level VM.

On second level VM, define and couple the Virtual CTC to first level
TCPIP before his IPL (COMMAND into Directory is a good place to set it).
After the IPL, DEDICATE the CTC (the second level thinks it is a REAL
CTC) to his TCPIP machine.
Done, you have the two TCPIPs connected by CTCs...

Work fine also for VTAM machines, RSCS, PVM, zOS and so long...

Re: Maximum Virtual Storage

[O'Brien, Dennis L]

Gary,

It depends on your hardware.  From Bill Bitner's z/VM System Limits
SHARE presentation:

 

Virtual machine size:

- Supported/Tested 1 TB (240)

- Hardware limits

* z10 8TB

* z9 1TB

* z990 256GB

* z900 256GB

 

That's for one virtual machine.  There's also a guest real limit of 8 TB
imposed by PTRM space limits.

Mark,

ISFC links can be ESCON CTC or FICON CTC.  I don't know why Hipersockets
aren't supported, but they're not.  If you really want to share SFS
filepools between LPAR's on the same CEC without using a CTC, you could
set up IPGATE using TCP/IP over a Hipersocket.  Note that IPGATE is not
officially supported.  It's a sample program.

From the connectivity manual -

VM domain controllers must use channel-to-channel (CTC) links to be
attached to

other VM domain controllers in the CS collection. The VM domain
controllers may

be running ISFC or VM PWSCF to participate in the CS collection.

 

Are these links ESCON CTC or FICON CTC - or does it matter?

 

Why doesn't ISFC take advantage of Hipersockets? You've got this high
speed network built in to System Z, seems odd that I have to use old
fashioned hardware connections.

Re: Mixed page volume sizes

[O'Brien, Dennis L]

In our case, we're talking about going from 76 GB to 140 GB.  We're trying to 
stay ahead of requirements, so suggestions such as look at your performance 
monitor don't really work.  The workload that will use the additional capacity 
hasn't arrived, yet.  I need to submit my disk requirements for paging to our 
Storage team, because it takes them a month or two to add the disk.  I can't 
afford to wait until performance gets bad.

Right now, this system has about 30 Linux guests, all running WAS.  Most of 
them have 6 GB of virtual storage.  This is a development system, so it's 
actually larger than our production systems.  Developers like to have several 
levels of testing (UAT, SIT, etc) for each production server.  One of the 
drivers for the upgrade is a proposal to add a 28 GB Linux guest to 
development, and one to each of two production systems.  The wisdom of having a 
single guest that large remains to be seen, as does the actual requirement for 
that much storage.  I know about SET REORDER and all that.  If they really do 
need that much storage, they might end up with multiple smaller guests.

S if you had guests averaging 18GB each, and you follow

That would give you 100 such images per VM .. (250 volumes times the

I know this rough but am I headed in the right direction?  I'm making the

Mixed page volume sizes

[O'Brien, Dennis L]

On of our z/VM 5.4.0 systems is about to grow to 140 GB of storage.  Given our 
target overcommit ratio of 3:1, and IBM's advice to keep paging space no more 
than 50% full, this should just about fit onto 240 or 248 3390-3 sized volumes. 
 My question is what will happen the next time we add storage.  Clearly, we'll 
have to start using 3390-9 sized volumes for paging.  Would we be better off 
converting only enough volumes to satisfy the space requirement, which would 
maximize the number of devices, or should we convert all volumes to 3390-9 to 
keep them the same size?  My concern is that if we mix sizes, CP will try to 
allocate the same amount of space on each volume, and the 3390-3's will get 
more than half full.  On the other hand, maximizing the number of devices 
maximizes the number of concurrent I/O's.  Our Storage people aren't going to 
give me 240 3390-9's if I don't need them, so if I add another 32 GB of 
storage, my choice would be something like 212 3390-3's and 28 3390-9's, or 100 
3390-9's.  Which would be a better choice?

It's really up to you and your management's direction.

If you only have one system to maintain, once you get the hang of it it's 
not really all that hard to:
1) apply all maintenance to the 2nd level test system, 
2) IPL the 2nd level test system, 
3) perform some cursory (or more stringent, depending on your tolerance 
levels) tests, 
4) only then re-apply the maintenance (or copy minidisks if you really 
know what you're doing, which VMSES/E makes more difficult) to the 1st 
level system and schedule its IPL.

Applying the same maintenance twice can be viewed as tedious, but it does 
breed a bit more familiarity with the VMSES/E command set. 
But it also give you a chance to see what will be changed when you run 
PUT2PROD on 2nd level.  Some components are not especially good to run 
PUT2PROD on in a production environment (can you spell: TCPIP?) when users 
(and your management) might notice that component being bounced.

BTW, after applying maintenance I consider it a good idea for each of the 
component which were serviced, to use VMFSETUP so that their disks are 
linked and accessed, then issue: FILELIST * * * (TODAY ISO
then browse around to see what was changed.  That breeds even *more* 
familiarity with VMSES/E and what it has done for you.  That familiarity 
can be handy when something goes bump in the dark.  :-)

Central vs. expanded storage

[O'Brien, Dennis L]

I heard from a couple of performance people at SHARE that we should have 20% to 
25% of the total storage in an LPAR configured as expanded storage.  Naturally, 
that's a guideline and the proper amount varies by workload.  What should I 
look at to determine if we have enough expanded storage?  We use Velocity's 
ESALPS suite.  The systems that I'm most concerned about have a Linux guest 
workload.  One of them is all WAS, and the other is a mix of WAS, Oracle, and 
some other things.

I've heard that WAS isn't the best choice for System z, but that's not the 
focus of my concern.  We have the workload that we have, and I just want to 
make it run as well as it can.

FEATURES ENABLE STP_TIMEZone looks interesting.  Does this mean that I could 
eliminate the Timezone_Definition and Timezone_Boundary records from SYSTEM 
CONFIG?  If it does, I presume that the STP server would have to be configured 
with a timezone (Pacific, Eastern, whatever).  The STP server would need to 
know the Daylight Savings Time rules for the country it was in.  It would also 
mean that we would have to pick one timezone for the STP server, and all 
systems connected to the STP server would use that timezone.  Right now, we 
have a mixture of timezones in one data center as a result of acquisitions and 
data center moves.

We would still be responsible for bouncing service machines that don't get

You should be able to find the text in the prodid MEMO file (for example,

In case others have the same question, here's the contents of the memo as
they relate to VM64814:

Memo to Users for APAR VM64814

The following configuration file operands have been added by this APAR:

FEATURES ENABLE STP_Timestamping
 tells CP to enable the STP protocol (if the STP facility is
 installed) and apply timestamps to all XRC-capable DASD devices.

FEATURES ENABLE STP_TIMEZone
FEATURES ENABLE STP_TZ
 tells CP to enable the STP protocol (if the STP facility is
 installed) and obtain timezone information automatically from the STP
 server.

FEATURES ENABLE XRC_OPTional
 when STP_Timestamping is also enabled, this will allow non-
 timestamped I/O to be issued whenever STP is in an unsynchronized
 state, as opposed to deferring I/O until STP synchronization com-
 pletes.

FEATURES ENABLE XRC_TEST
 tells CP to timestamp I/O regardless of STP availability.  This
 option is meant only for vendor and testing purposes, and can only be
 specified for systems running within a virtual machine.


The following commands have been added by this APAR:

QUERY STP
 returns information regarding the current state of STP usage on the
 system.


The following commands have been modified by this APAR:

DEFINE TIMEZONE
 this command cannot be issued while STP_TIMEZone is in effect.

SET TIMEZONE
 this command cannot be issued while STP_TIMEZone is in effect.

QUERY TIMEZONE
 this command was updated to include STP timezone boundary information
 when STP_TIMEZone is in effect.

  HCP986I
  HCP987E
  HCP988I


The following publications have been modified:

putting in, or that an additional step was required to activate it.

I found a couple of references on the IBM site that said VM64814 and VM64816 
would add the function.  VM64816 is assigned to a programmer.  Does VM64814 
do anything without VM64816?  Will VM64816 provide the documentation?

zVM 6.1 requires a z10, so you can't go to 6.1 until you have a z10.

Re: Disaster Recovery TCPIP Address Issue

[O'Brien, Dennis L]

I use an exit in node DTCPARMS that checks the DR status using the CPU serial 
number, e.g.

.*---
.* Add user exit to stack startup
.*---
:nick.TCPIP:type.server  :class.stack
   :exit.DRCHECK 
 
.*---
.* Add user exit to MPROUTE startup  
.*---
:nick.MPROUTE  :type.server  :class.mproute  
   :exit.DRCHECK

The exit is specific to our environment, so I won't post it.  It calls another 
EXEC that determines whether we're in DR by checking the CPU serial number.  
The operator is also prompted at system startup to tell the system whether 
we're in a DR test or real disaster.  DR tests are conducted behind a firewall, 
so we use different OSA's for test and real DR.  For the stack, it copies a DR 
version of PROFILE TCPIP to TCPIP 191.  For MPROUTE, it returns :Config. with 
the name of the appropriate MPROUTE CONFIG file.  We don't use SYSTEM NETID or 
SYSTEM CONFIG to change the node name for DR, because we have things that are 
dependent on the node name.

* FTP the file to CBDSACT user id under VM.

* Import the file using the CBDIODSP 

 

At this point, she hits a snag because the import expects a reader file.
Is that solved simply by SPOOL PUN * followed by PUN fn ft fm (NOH or is

Subject: [IBMVM] Windows Enabler Appliance on System z Now Available

 

As discussed at WAVV:

 

Based on requests from a number of customers, we have assembled a
virtual machine appliance for System z and z/VM to permit running x86_64
based operating systems and applications on System z10 hardware in
virtual machines. The appliance has been tested with (and passed) the
Microsoft Windows Server Hardware Verification test, and Windows Server
2003 and 2008 virtual machines have been successfully deployed and run
applications such as Exchange 2007 and Sharepoint. 

 

What is the intended use?

 

The appliance is intended to provide a immediate way for Intel server
applications that perform mostly I/O intensive applications to run on
System z hardware, and is best suited for server applications such as
Exchange or Sharepoint hosting. The appliance does not include licenses
for any OS (eg Windows, etc)  or the applications to run within the
appliance.  

 

Based on what IBM has publically shared about System z hardware futures,
we see this as a roadmap item that will be expanded and optimized to
take advantage of new direct execution capabilities as they become
available. We are discussing how enhancements to speed up the emulation
could be done with IBM, and will share more as things evolve.

 

How's It Work? 

It's based on the research with dynamic instruction simulation done as
part of the OpenSolaris for System z work and a clean-room x86_64
instruction description. It is (by definition) not as efficient as real
iron, but it provides a way for x86_64 applications to be run without
adding additional hardware to the data center. 

 

What Do I need to Run it?

 

A z10 and z/VM 5.4 or greater. It may work on pre-z10 machines, but it
is likely to consume an unacceptable amount of overhead CPU.  Both IFL
and CPs are supported. 

 

How do I get a copy? 

 

The appliance is available according to a mutual assistance model based
on how many physical CECs you plan to deploy it on. You can contribute
money, people or resources to obtain a copy.

Has anyone set up the SSL server in z/VM 5.4?  There are a couple of BFS

They would be:

Re: Using HCD on an IFL-only Machine

We used to have z/VM-only machines here.  The IOCP was maintained by the

IOCP.  These were 2064's in basic mode, but I would imagine that the
process still works for newer machines.  I don't know a lot about the

managed with HCD by the z/OS folks. No worries!
 
Now we are getting an IFL-only box and want to maintain this
organizational relationship. I am not familiar with HCD on z/VM but from
doc it looks like IODFs can be managed by z/OS, exported and imported
into z/VM, where a miracle occurs and the I/O config can be changed
dynamically.
 
Is anyone else doing this? Is there any simplifed doc available

Mike,
Yes, you have to download the (big honkin') files to a PC, unzip there, and 
upload to VM.  In my case, I upload to Linux and copy from there to VM.  Thus 
Chip's comment about using three operating systems to install one.  There's 
probably a way to use a Linux guest to download from IBM and unzip.  I haven't 
tried it, because the files are downloaded from a web page, not an FTP site, 
and I'm not sure how to do that on Linux.  I imagine that I'd either need to 
set up a GUI on a guest and control it from my desktop, or use some kind of 
command-line tool that can download a file from a URL.

I vaguely recall a PKZIP for VM product.  If you had such a thing, you might be 
able to unzip the files on VM.

It's been a long time since I used a 56k modem.  IIRC, they download at 56kbps

Re: First time DR excercise

Mike has a lot of good ideas here, but I'll comment on a couple of minor points.

1. We have multiple VM systems in our shop, so changing the node name during a 
disaster would cause more problems than it would solve.  We have too much code 
that does things like If node = 'VMSYS1' Then Do ... to be able to tolerate 
new node names for DR.  We update the logo file to change RUNNING in the 
lower right corner of the screen to DR SYS.  The node name stays the same.

2. The other thing I would never change during DR is the time zone.  Your users 
have scheduled jobs based on the normal time zone of the system.  If you change 
the time zone, those jobs will run early or late.  If the jobs run late, users 
will be late getting their reports, data feeds, or whatever.  If the jobs run 
early, they may run before feeds from other systems have arrived.  Either one 
is not good.

PRODVM: RECOVERY: CP_Owned   Slot  2   VMSP02 OWN 
PRODVM: RECOVERY: CP_Owned   Slot  3   VMSP03 OWN 
  CP_Owned   Slot  4   RESERVED 
... and more RESERVED slots for future SPOOL growth as needed... 
3) or in the very last slots (i.e. ending with SLOT 255 backing up from 
there with plenty of RESERVED slots above),

... and more RESERVED slots above for future SPOOL growth as needed...  
  CP_Owned   Slot  252 RESERVED 
PRODVM: RECOVERY: CP_Owned   Slot  253  VMSP03 OWN
PRODVM: RECOVERY: CP_Owned   Slot  254  VMSP02 OWN 
PRODVM: RECOVERY: CP_Owned   Slot  255  VMSP01 OWN 
  4) Regardless of their top or bottom location, include flashing 
red-neon comments (that's just a point of emphasis, don't search IBM doc 
for flashing red-neon comments), warning you and your sysprog heirs to 
NEVER CHANGE SPOOL VOLUME SLOT NUMBERS WITHOUT A CURRENT SPXTAPE BACKUP 
(and a thorough plan already tested on a 2nd level system, and ... an 
off-site copy of your resume)!

Now, about that SYSTEM CONFIG file.

Let's presume that your normal product system runs on  an ancient, creaky

And that your employer has a number of shiny newer boxes with known serial

with z/VM 5.4.0.  I unzipped the install and RSU files, and put all the
CKD files in a directory on my PC.  I then used Samba to upload the
files to a Linux guest.  The nice thing about Samba is that I can use
Windows cut-and-paste to copy the files.  If the transfer gets
interrupted, it's easy to pick up where I left off.  I work from home,
so the upload takes about 16 hours.  I didn't have any interruptions
with 5.4.0, but I have had them when uploading earlier releases.  Once I
have the files on Linux, I either install from the Linux FTP server, or
use FTP to copy the files to a CMS minidisk.  For either approach, I
follow the instructions in the manual.

Subject: [IBMVM] z/VM 6.1 Install

 

I feel like a fish out of water. I ordered z/VM 6.1 to be delivered
electronically, which may have been a mistake. 

 

* I have downloaded to the PC, and uploaded to a VM disk, the
files pointed to by the notification letter. These were files that have
TERS file types. The recfm/blksize are F/1024.

* I DETERSEd the ones identified as the System DDR.  These files
are V/4095. 

 

Now what?  I find conflicting instructions. Depending on where I look, I
see (1) no DETERSE step, which cannot be right for these files, with
instructions that say that the files must be fixed/1028, which fits
neither the before nor after DETERSE lrecl, or (2) the DETERSE step is
included followed by a reference to a non-existent manual. 

 

I see no reason to DETERSE the other files until I have, as Paul Harvey
used to say, the rest of the story. That will only give me more files
that I will probably have to erase when I must try some different
download.  

 

I opened an ETR after running around in circles until I was dizzy on the
support web site pointed to by the notification letter. I have no idea
when I will get a response. The list is usually faster. Please Help!!!

Different PROFILE TCPIP for DR

[O'Brien, Dennis L]

I'm setting up a DR process for a new system.  I need to use a different 
PROFILE TCPIP when the system is up in the DR site.  I know that the easy and 
wrong way is to update TCPIP's PROFILE EXEC to copy the correct PROFILE TCPIP 
to the A-disk.  I'm trying to do it the right way, by using a server exit to 
pass the name of the profile to the stack.  I can't figure out what to pass to 
get the stack to use a different profile.  I've tried

Return ':Command.TCPIP DRTEST TCPIP *

and

Return ':Parms.DRTEST TCPIP *

Both yield:
DTCRUN1011I Running server command: TCPIP
DTCRUN1011I Parameters in use:
DTCRUN1011I  DRTEST TCPIP *

The problem is that the parameters don't seem to influence which file gets 
used.  I don't have userid or node TCPIP files, so the stack reads PROFILE 
TCPIP.  The userid and node name don't change during DR, so using those files 
wouldn't help.  Is there a way to tell the stack what file to use, or should I 
just use the exit to copy the correct file to the A-disk as PROFILE TCPIP?

FCP Redbooks

[O'Brien, Dennis L]

Our storage architect asked me about using FCP channels for Linux on z/VM.  Are 
there any good Redbooks or other documentation that's recent?  He couldn't find 
anything that mentioned z10.  He's particularly interested in limits 
(guests/LUN's/device addresses per channel, etc).  CP Planning and 
Administration discusses configuration, but doesn't mention limits.  I did find 
a discussion of limits in the Introducing N_Port Identifier Virtualization for 
IBM System z9 Redbook paper.  That paper is from 2006.  Has anything changed 
since then?  I also found Steve Wilkins' presentation Using z/VM in a SCSI 
Environment.  It has some good recommendations.

more devices means more concurrent I/O's.  Has anyone actually tried changing 
from 3390-3's to one-third as many 3390-9's?  If you have, was there a 
measurable difference in performance?

because z/VM doesn't timestamp its I/O but Linux does.  I'm being told that HUR 
doesn't support Linux timestamps.  Is that true?  Allegedly, this lack of 
support means that a z/VM replication environment would need to be separate 
from our z/OS replication environment, including a separate z/OS LPAR to 
control the replication.

Performance Toolkit setup

[O'Brien, Dennis L]

I'm setting up Performance Toolkit according to the instructions in
Getting Started with Linux on System z for z/VM 5.4.0.  This is just
for a proof of concept, so I'm starting with the defaults.  The PROFILE
EXEC for MONWRITE on page 144 contains the following MONITOR EVENT
commands:

'CP MONITOR EVENT ENABLE ALL'
'CP MONITOR EVENT DISABLE SEEKS ALL'
'CP MONITOR EVENT DISABLE USER ALL'
'CP MONITOR EVENT DISABLE SCHEDULER ALL'

The PROFILE EXEC for PERFSVM on page 145 contains the following
commands:

'CP MONITOR EVENT DISABLE ALL'
'CP MONITOR EVENT ENABLE STORAGE'
'CP MONITOR EVENT ENABLE I/O ALL'

The settings of MONITOR EVENT APPLDATA, MONITOR EVENT NETWORK, and
MONITOR EVENT PROCESSOR depend on which PROFILE EXEC is executed last.
Are these events important?  I don't expect to have applications
generating events, so I don't think I care about APPLDATA.  Varying
processors on or off would be extremely rare.  That leaves EVENT
NETWORK.  Are events such as virtual guest adapter initialization or
termination valuable in performance analysis or problem diagnosis?

z/VM 5.2.0 is out of support from IBM, so it doesn’t officially “support”

Re: some RACF and CP questions

[O'Brien, Dennis L]

5-1. The ESM hook into CP is configured by replacing the HCPRPx stubs in
CP.  It's not in a configuration file.  There might be a Product record
in your SYSTEM CONFIG file to enable RACF, like there is for RSCS, but
that doesn't prove that RACF is active.

 

5-2. The Journaling statement in SYSTEM CONFIG controls this.

 

5-3. Features Enable Clear_Tdisk in SYSTEM CONFIG sets T-disk to be
cleared on system IPL and when detached by a user.  This is better than
requiring a format upon allocation, because there's no sensitive data
sitting on unallocated T-disk areas.  It's cleared as soon as the
previous user is done with it.

 

5-4.  This isn't controlled by CP.  VM:Secure and VM:Director can be
configured to always format old minidisks when they're deleted.  I
suspect DIRMAINT can, too, but we don't use DIRMAINT here.

What security problems in T-Disk?  If you enable Clear_TDisk, there's no

If you have the page space to support it, you can get by without TDSK space by 
using V-disk. It is always cleared very quickly, by CP, before it is used and 
does not pose the security problems that you find in T-disk. A large V-disk is 
also faster to format than is a T-disk of equal capacity.

Re: TDISK and SYSTEM CONFIG question.

Stephen,

If you Enable the Clear_Tdisk feature, all system T-disk space is
cleared at IPL time the entire T-disk is cleared when it's detached, and
if you attach a new T-disk volume to SYSTEM, all space on that volume is
cleared.  Turn on the feature, IPL, then detach one of your T-disk
volumes from SYSTEM and reattach it.  Immediately enter Q ALLOC TDISK
and you'll see that all space is in use.  Issue it a few times over the
next minute or two, and you'll see the space free up as it's cleared.

There is an option in the SYSTEM CONFIG file to clear the T-DISK.  It is
in the FEATURES list and CLEAR_TDISK can be either ENABLED or DISABLED.


The manual states that it clears only cylinder 0 (zero) or the first
eight blocks on the temporary minidisk when it detaches the minidisk. Do
they mean the minidisk that is created with the DEFINE statement or is
it the T-DISK area that gets cylinder 0 or first 8 blocks cleared?

Further, and in the same manual,  it states that you can clear each
T-DISK before it is reassigned.  It depends on your point of view but
this seems contradictory. Clear, in my opinion, means the T-DISK created

I'm not trying to point out discrepancies in the manual, I'm curious as
to why it was originally needed and when does it actually get cleared.

(An external auditor is really hung up on this area not being cleared.)

Subject: [IBMVM] VM lockup due to storage typo

Does anyone have an idea of how we might have gotten out of this without 
an IPL?

VM LPAR has 175G of memory and a flock of Linux Oracle guests... 
Several guests needed more memory added so the directory was updated and 
one by one the guests shutdown, logged off and back on.  So far, so good.

But... In changing the memory for many guests, and it being late at 
night after a long day, while meaning to set a guest's memory to 9728M, 
it got set to 9728G.  When that guest was cycled we see the message on 
the console that it's memory was limited to 8TB (HCPLGN093E), then the 
VM system appeared to freeze.

We couldn't get in via TCP/IP, or the HMC Operating System Messages 
screen, or the HMC Integrated 3270.

Finally had to IPL.   Even that was wierd as I'd have expected the Load 
Normal to shutdown, it just IPLed.   We did NoAutolog, fixed the typo 
and all came back up ok...

I suspect CP was scrambling paging everything in the world out as Linux 
tried to initialize that 8TB of memory...   But I'm surprised I couldn't 
even get into the HMC consoles (to kill just that one guest as opposed 
to all of them)..

Any thoughts?

The statement, Since TDISK are in your CP_Owned list, they can't be brought 
offline on a running system is incorrect.  There's no restriction on detaching 
CP Owned volumes from system, as long as no space is in use.  Frank stated that 
as one of his assumptions.  Once it's detached, you can vary it offline if you 
want to, but that's not necessary.  CP will read the new allocation map when

Well, once again it depends...  you can adjust it (use CPFMTXA to change 
the cylinders allocated to TEMP) on the fly.
But CP only reads the allocation but map when the DASD is brought online. 

Since TDISK are in your CP_Owned list, they can't be brought offline on a 
running system.  So CP cannot re-read the allocation bit map to find the 
added or removed TEMP cylinders. 

(Note: CP does update bits in the allocation bits to indicate usage of the 
previously defined areas - so changing the use of previously allocated 
areas will end up with CP re-writing them anyway - not a good idea). 

You can add a while new volume for some purpose (temp disk, page, spool, 
etc.) on the fly, and CP can read that new DASD's bitmap when it comes 
online.

You can issue the mount command from another LPAR.  If the other LPAR is

recover your main system.  Normally, you would maintain the small system
as a guest of your main system, but you would configure it so that it
can also be IPLed first level.  If you have to recover your main system
in its usual datacenter, just IPL the small system and start your
restores.  For disaster recovery, you could backup and restore the small
system using full volume dumps from z/OS.  Note that this works for
restores, but not standalone dump. For standalone dump, you need to have
another LPAR available to IPL the small system.  If you IPL it in the
LPAR that you want to dump, the IPL will destroy the data that you want
to dump.

Subject: [IBMVM] Stand-alone IPL of a Virtual tape

 

We are starting to implement a virtual tape system in our VM system;
they are planning to get rid of our silos.  To us, it is a black box;
the zOS guys say just mount these volumes on these tape devices; treat
them like real cartridge on real 3490 drives and you're good to go.

 

I've tested the volumes  devices using RMSMASTR, VMTAPE, VMBACKUP, DDR
and for the most part, they work well. 

 

My question is:

 

Recovery process usually starts with a stand-alone program, like DSF or
DDR. If we have to IPL a stand-alone program like DDR that happens to be
in a virtual volume onto a bare LPAR, how is this done?

 

Thanks for any info.

Does it run on a PC in Windows, Linux…what?

 

Is Hercules a shell for z/VM and/or z/OS and if so where does one get legal 
copies of both?

 

Being that I’m still on the beach I’d like to know where I can find out more 
about Hercules and install it on my home PC.

 

Being out since the end of March … thanks to lay offs at the bank I worked for 
isn’t much fun and a mind is terrible thing to loose.

 

If I had something at home to fool around with, that would be great and perhaps 
keep some of my skill warm.

Re: z/VM 6.1 and Hercules on Z9

I don't think IBM would see you a new license for z/VM 6.1 on a z9, but if you 
have an existing z/VM version 5 license with Subscription and Support, you're 
entitled to version upgrades at no extra charge.  Read the fine print in your 
license agreement.  You shouldn't expect support for z/VM 6.1 on a z9, but you 
might be entitled to run it there.  Just don't expect it to run well.

Re: SFS - Moving File Pool Minidisks to Different Physical Devices

[O'Brien, Dennis L]

You can create a storage group 3, move your filespaces to it with
FILESERV MOVEUSER, then disable storage group 2 with FILEPOOL DISABLE
GROUP 2 EXCLUSIVE DETACH.  You can then replace the old storage group 2
minidisks with 1-cylinder minidisks.  This isn't completely transparent,
because FILESERV is a dedicated maintenance mode command, but it does
allow you to move users in batches, without requiring an outage long
enough to back up, format, and restore the entire pool.  I have code in
the SFS server PROFILE EXEC to look for a move list and process it at
system IPL time.

Re: Where is z/VM CSE

[O'Brien, Dennis L]

Sunny,

CSE itself is not a product.  It’s part of z/VM.  Chapter 10 of CP Planning and 
Administration describes the requirements and capabilities of CSE.  RSCS is 
required if you’re using DirMaint to maintain a single source directory for the 
cluster, and you don’t enable cross-system SPOOL.  PVM is required if you use 
cross-system SPOOL.  Chapter 5 of the Directory Maintenance Facility Tailoring 
and Administration Guide discusses directory sharing in more detail.

 

We use the XLINK feature of CSE, but not the other parts.  We have VM:Secure, 
so I wrote code to keep Linux guest directory entries in sync.  The rest of the 
directory is separate for each system.

confidential information, are you sure you just want to put your DASD 
backups on a physically-tiny thumb drive?  I lost my first 16G thumb drive 
within months even though I was pretty careful with it (having paid out of 
pocket for it a year ago). 

Most people don't have 3480, 3490, or 3590 tape drives sitting around to 
read company data.  Most people _do_ have PC's with USB ports, even though 
trying to figure out whatever format a 3390 dump might be in would be 
quite a challenge.  But it would still be a matter of getting your 
security officer to sign off on something s/he doesn't really understand.

If you still think it's a good idea (and it *does* have merit), do you 
want encryption with that order?:-)

Any other considerations to discuss before making recommendations to IBM?

Re: Using DVD to restore an existing z/VM?






I think what we really need is the ability of the HMC to use a USB as an
input device (e.g. be able to IPL a standalone program off of a USB
stick, and have a program like DDR use the USB stick as an input or
output device), and perhaps the ability of z/VM to read AND write to the
USB so that we can write iplable decks and DDR content there.

If a vendor (IBM or otherwise) wants to further exploit that capability
with products that make it easier, so much the better.  But the basic
ability to do I/O to the device via the HMC and OS are what I'd be
looking for.

That's true, but it goes even deeper.  Backup/Restore is vendor space,

including IBM's own offerings.   We can't do things in the base product
or 
give away things that would negatively affect the value of such
software. 
But that's all stuff that gets sorted out when the actual requirement is

analyzed by product planners and we understand what technology is needed

and how it is best delivered.
