Re: SLES 11 SP1 install can't find disks?
Hi Mike - I do recall running into this.. but it's been a few months. Have you retried the install now that the disks are formatted? IIRC, I was able to get through the install on my 2nd attempt. It could be that I ended up formatting the disks with CMS and then retrying - my memory is hazy. I suspected a bug but was in a hurry at the time and just trying to get through an install..

Re: SLES 11 SP1 install can't find disks?
Hi Doug - Yes, it does seem similar if CMS formatting was really the cure -- unfortunately, my memory isn't real reliable in this case. It could be that the experience we had with RHEL5 makes me try this as possibility now too ;-) What I'm trying to do by CMS formatting the disk is eliminating any possible Linux formatting that is already there.. I have found things like leftover LVM info (from another guest) can confuse things. Linux formatting the disk also works (e.g. using Sine Nomine's LXFMT instead of FORMAT) and avoids needing to format during the install. Most of the issues I've run into with both RH/Suse are with disks that weren't 'cleaned' and came from a previous guest. One nice solution I've implemented in the past is to have the DIRMAINT 'clean' exit issue LXFMT instead of FORMAT so that all DASD returned is already Linux formatted.. but it's usefulness depends on whether you use the same size minidisks for all guests. (I tend to use 1-END disks and not chop up volumes). Scott Rohling On Tue, May 17, 2011 at 7:07 AM, William Carroll carro...@nationwide.comwrote: Scott Doesn't this remind you of the issue we had with RHEL5 and it not recognizing the dasd during a kickstart? basically if we CMS formatted it worked but a dasdfmt didn't and we got a do you wish to format this volume or similar message. it was because RH changed the scripts method of checking the dasd for that issue as I recall. RH i think was trying to make the script more common between platforms. Not saying Suee is doing the same thing but sounds like a similar issue? Just sounds like a similar issue.

To clarify.. the vdisk is specified in number of 512 byte blocks.

Re: Mono and ASP
I too wish IBM would push Linux harder internally .. I've been running Ubuntu with the IBM 'layers' on my laptop and don't find anything I can't do. One difference is the AGN Dialer.. Windows still offers modem support and callin numbers last time I looked -- but on Linux - you strictly use the 'existing connection'. WebSphere Everyplace was abandoned as far as I know.. it was cool.. but it also had security issues - I remember suspending my laptop and still being connected when I resumed with a new IP address.. which sounds neat but isn't secure. I use Linux on all my personal and work machines.. and am very happy. I still do keep a Windows partition around and some Windows virtual machines for the rare times I have to use it.. which may be why the push to Linux within IBM isn't done with more force. If we're going to have an MS license for 'just in case' -- then there's no incentive to move off of it for most people. Staying compatible with our clients is definitely a factor too. shrug I do think it's great how IBM has allowed us to expand beyond the c4eb install (which was/is fedora based?). I like Debian and being able to use Ubuntu and point to IBM repositories for the extra stuff is great..

It's been awhile since any of the business apps (like travel) including externals has required IE.

If you're really talking about one lonely IFL - you'll likely want to dedicate it and let z/VM manage the sharing on a single LPAR.

Re: Cloning question for zLinux
It's not necessarily true that you don't need to wait until the copy completes... if the FLASHCOPY gets an RC0 - ok -- but if it gets a RC indicating for example - that there are already pending flashcopies for the device -- I'm not sure offhand if DATAMOVE tries again or fails the workunit.

Re: Defining second OSA port on the chpid on SLES10 SP3
Ok - I thought this was a distro specific issue -- RHEL and SLES use entirely different files to configure network devices ... I just thought the end result was supposed to be what is documented in Device Drivers (a resulting /sys setting...). I thought RHEL and SLES made up the configuration options used to get there? No? Scott Rohling p.s. To me - this is a configuration file -- and anything that might be in it should be documented shrug. Things like QDIO architecture are a different fruit.

Some things you just want people to use the documented interfaces for, and let the tools handle things.

Re: Shared filesystem in redhat, MQ redundancy
Are you referring to XLINK? If you define XLINK volumes and systems in SYSTEM CONFIG - and XLINK FORMAT the volumes -- then you get 'LINK protection' across systems. From VM1 - attempt rw link to minidisk on VM2 that already has RW link ... your LINK will get a RC indicating the disk in in RW by 'VM2'.

Re: RH 5.5 Local TOD...
Are you talking about the UTC setting? You can select whether UTC is used or not at install..from a blurb on the web for RHEL5: To change your time zone configuration after you have completed the installation, use the *Time and Date Properties Tool* . Type the system-config-date command in a shell prompt to launch the *Time and Date Properties Tool* . If you are not root, it prompts you for the root password to continue.

Re: LVM, PAVs, and cloning
PAV can be defined at the minidisk level (any size minidisk) by adding a MINIOPT PAVALIAS statement after the MDISK statement... Example: MDISK 200 3390 2500 50 LX0001 MR MINIOPT PAVALIAS 1200 2200 3200 The virtual machine will now have a 200,1200,2200,3200 all pointing to the same physical disk and each of which can have a single pending i/o.

Re: Need a little help with a Linux script
I still code Rexx almost daily on z/VM, but have tried to use bash scripts on Linux, with the occasional call to awk and perl. There are a few reasons for this - but it's mostly because I want/need to write code that can run on any Linux system, without requiring an extra package that most probably don't have installed. There are too many great things about Rexx for me to ever give it up. I exploit the flexible array structures shamelessly and love the parse command. It's hard to beat for readability IMHO. I'll probably never be able to code things as quickly with other languages as I can with Rexx - but that's probably understandable after 25 years of almost daily use.

Re: Memory Allocation
I would ask why you don't allocate it all? Say 14G of cstor and 2G of xstor?Are you planning for a 2nd z/VM LPAR? 6GB would likely be very sufficient for z/VM and a single Linux DB2 Conn Server guest. I'll venture that much if it helps :-) And probably without even paging.. What it mostly depends on is the virtual memory size of your guests. As long as you have sufficient paging space - you can overcommit your memory. 2 or 3:1 is likely as far as you want to go unless you're willing to suffer performance degradation. That is - if you have 3 Linux guests using 4G of memory each -- you would be overcommited at a 2:1 (V:R) ratio. It also means that since you are overcommitted by 6GB - you'll want 12GB of paging space (6 3390-3). You want to have twice as much paging space because you want paging to stay at 50% or less.The paging requirements are based on 'worst case', though -- meaning that all 3 guests are using ALL of their memory and are all actively paging.

Re: HCPGIR450W and HCPGIR453W after editing user direct
An IPL of an OS in a virtual guest is not the same as 'destroying and recreating' the virtual environment the OS is running in. If you use a desktop virtualization solution (I use VirtualBox) -- it's much the same - there are certain changes to the virtual machine definition that require you to stop the virtual machine and start it again. (or you can't change the definition unless the virtual machine is stopped, unlike z/VM, where you can always change the guest directory definition running or not - but you may need to stop it and restart it to see those changes).

mon_fsstatd - filesystem monitor records
I am trying to use the mon_fsstatd driver (s390-tools) to generate monitor records with Linux fileystem stats. The guest has OPTION APPLMON and ability to write monitor records. Records 'do' seem to be generated - but it seems like it's only for a single filesystem (/dev/dasdd1, which happens to be the last listed if you do a df -h). According to the device drivers manual -- a record should be generated for each physical mounted filesystem. I'm only seeing one. As an aside - I am viewing the records on z/VM by linking to MONWRITE 191 and using some creative PIPEing to translate the ascii fields to ebcdic, etc... Basically getting all records with 'LNXAPPL' in ascii and parsing them. So pretty sure I'm not missing records that are being written for APPLDATA ...

The table headings are off by one - can't seem to cut and paste it

groupadd nje 2/dev/null; \
groupadd njeanon 2/dev/null; \
useradd njeanon -g njeanon; \

Similarly, when the RPM is being uninstalled I need to get rid of those
entries. Again, easily done with %postun:
%postun
rm -rf %{nobodyhome}
userdel njeanon 2/dev/null
groupdel njeanon 2/dev/null
groupdel nje 2/dev/null
However, if I am upgrading using -Uhv then I get the %pre and %postun
sections run as part of the upgrade. This means that the work done in %pre
gets undone by %postun. If I was simply doing a rpm --erase I would be
satisfied but doing -U then this is not what I want.
So my question is, how do I prevent -Uhv undoing the %pre work (to be
pedantique if it's doing an upgrade then the groupadds aren't issued
because
the check tells me the entries are already there).

Re: managing rhel disk space
Yep -- your answer is LVM ... for the Linux OS directories - I typically recommend: - Keep root as a single partition on a minidisk (not LVM) on it's own filesystem. /boot should stay in this partition or have one of it's own. - Create a 'system' volume group with one or more minidisks (1 to end - don't mess around with smaller ones unless you're using 3390-27 or bigger) - Create logical volumes (I just name them the same as the mount point - var,tmp,usr, etc) for each mount point you want separated: /var, /tmp, /opt, /usr, /home and give them the space 'required'. mkfs a file system on each logical volume and indicate they should be mounted in /etc/fstab (e.g./dev/system/usr/usr ext3 defaults 1 1) When more space is needed - just add another minidisk to the system volume group - divide up the new space to the logical volumes that need it -- resize the filesystems - done. For application data, database, etc -- make a different volume group (e.g. appdata) and 1 or more logical volumes within that -- then you can expand them the same same way.

Also, down the road, when they discover that they really should have asked for double that amount, you just add the space to the volume group, give it to the logical volume, and extend the filesystem.

Re: Full volume restore of an LVM DASD
As long as all of the right uuid/lvm identifiers are found on any online disks - LVM doesn't care about device addresses.

Re: Full volume restore of an LVM DASD
Something like this?: umount the filesystem(s) the LVM is being used by vgchange -an vgname (deactivate the volume group) chccwdev -d 2912 (deactivate 2912) chccwdev -e 372f (activate 372f) pvscan vgscan vgchange -ay vgname (activate the volume group) mount -a Note - I've never tried this... these are just the steps I would think would need to be taken.Also - to unmount things properly - you probably have to do an 'init 1' - that may be problematic, depending on terminal access.

My guess is that you are trying to flash to a minidisk for which the previous flashcopy has not yet physically completed.

A complete log-off and log-on is necessary to make the guest's runtime state reflect the changes made to the directory, unless you're using specific CP commands to perform these changes manually and just updating the directory to make sure the changes stick when the guest is logged off and on in the future. Or, for that matter, did you attach the disk without updating the guest's directory statement? Without updating the directory (either directly or through whatever tool you may be using), the disk you attached will only remain attached for as long as the guest is logged on - and won't be re-attached upon subsequent log-ons. ~ Chris On Thu, Jun 3, 2010 at 9:17 AM, LJ Mace ljmace1...@yahoo.com wrote: I do have notes and I thought all that had to be done was att to the guest then logon to the guest then yast would indeed see it.

Re: SWAPGEN
It's also nice to be able to stack a command that will be executed after the PROFILE EXEC finishes (as long as it 'does' finish and not IPL something): CP XAUTOLOG LINUX1#AUTOSTRT AUTOSTRT would be stacked when the guest is started -- and then (hopefully) executed. So we don't want anything in the PROFILE EXEC to mess with it. That's why 'well behaved' programs should always use MAKEBUF/DROPBUF or restore the stack contents if they do mess with it. The above is an example of how we automated a 'self cloning/configuring' process at one customer of mine. The common profile EXEC didn't rely on AUTOSTRT falling through though -- it noticed it was in the stack and so called AUTOSTRT EXEC itself -- or IPLed the Linux disk if it wasn't passed. Scott Rohling p.s. You need to do something like Address Command CP XAUTOLOG LINUX1#AUTOSTRT from an EXEC to not have the CP escape character get in your way on the command line.

How can I do that in REXX in Linux?
For example I want to capture the output of the df -h command and the
only way I can do that now that I've figured out is to do something like
this:
'df -h /tmp/tmp.file'
call read '/tmp/tmp.file' /* a read subroutine that reads the file into
a stem
'rm /tmp/tmp.file'
process the stem
I'm using Regina REXX on SLES 10 SP2.

Re: intro, request for advice ...
I think the answer depends on whether this is simply a 'proof of concept' or if the result is supposed to be a supportable solution. I'm guessing that for now, it's proof of concept.. so as Ruddy suggested, CentOS might be a good choice since it's RH based. I'm sure RH and Novell provide 'trial' periods too. Ultimately, as others have said - you'll need to choose one of the supported Linux distros for DB2Connect if your goal is a vendor-supportable solution. And even if proof of concept -- it's a 'good thing' to try and start with supported solutions and not have to start over when you've proved your concept and now want to run with it.

I don't think that quite does what Dale wants, because it will move the files within /usr to /usrold on the root filesystem. What really needs to be done here is to remount the filesystems on the correct mount-points, not to rename file paths. So the right way to do it is with mount: mkdir /usrold mount --move /usr /usrold mount --move /usrnew /usr The --move option atomically moves the filesystem, so there is no point at which it is unmounted. Open files on that filesystem will remain open, so it is OK to do the above when the filesystem is busy and is not unmountable. However, there is still a small window between the two mount commands in which a process might try to access a file within /usr and fail because it does not exist. If you have a lot of programs starting frequently, this is likely to be a problem. If you have a set of stable apps running but not execing new programs, you should be OK. On a production system, it would be best to bring it down to single-user mode first. - MacK. - Edmund R.

Re: Backup procedure for Linux
As others have said - rsync.The advantage is that it will 'sync' rather than blindly back up everything, even if it's already backed up. Example: rsync -avx / /media/backup Everything in / is written to /media/backup, but it avoids mounted filesystems (-x says stay in 1 filesystem). Keeps you from backing up /media/backup :-) You can add the --delete option to the above to do a 'true' sync and erase files on /media/backup that are no longer in /.You can run the rsync over and over and only the new or changed files are written to the backup target. There are tools (rdiff comes to mind) built around rsync to provide various features and function related to backup. 'man rsync' gives some good examples of use up front. I use it on all my home systems to do backups, move filesystems around, etc. Excellent tool.

Re: WWBD - One large VM LPAR or multiple smaller ones?
It sounds like you already have more than one z/VM LPAR though... If so.. then there's probably some limit on how many z/VM systems you realistically want to manage. In this case, I wouldn't slice things up except to separate workload or provide some type of HA - period. I would be after the minimum number of z/VM systems to have to manage my workloads or separate them. I'm not sure resource usage would be a factor, PRSM is pretty minimal as I understand it -- the real factor is people hours -- the more zVM systems, typically the more people hours needed. There's lots of automation around to minimize that, but in my experience, more z/VM systems requires more time to support.

We're in the process of migrating Websphere workloads from AIX to zLinux and figure we will need to add additional IFLs and memory.

When I say large, I'm talking maybe a 300GB/15 IFL footprint for one of our VM LPARs. We'd split that into maybe 2 150GB or 3 100GB LPARs. We would also gain more operational freedom if we split the workloads correctly, so it's looking pretty good to us. But, we don't want to do it if there will be too much additional overhead in terms of resource usage.

Re: Getting Started with zLinux
Mike - In this case, it's more the platform and the purpose that encourages command line. There are things that can resemble ISPF and text driven displays (yast on SUSE comes to mind -- you can run it from the command line and get a fullscreen interaction).Since everything is going to be network driven in terms of displaying data on a z -- text is much preferred to graphics in terms of performance and resource usage. And as a server, you want cycles spent on your services (web, file/print, database, whatever) rather than processing graphics for a monitor that probably doesn't even exist (servers racks, blades, whatever). If you're just playing with this on Hercules, not really working to implement it on z, etc ... go ahead and install a desktop environment and get comfortable. Just don't carry this over to z if you implement there. It's all about resource usage and how many servers you can run on one box when talking 'real' virtualization.

I'm just not sure when it will get high enough on the priority list to get developer time for a release. For mainframes, there is little to no advantage having /boot be on a separate partition. The same is true of almost all modern midrange systems, but it tends to persist there from habit/tradition. I do _not_ put / into an LV. I've had enough problems trying to recover the system when something went wrong to keep punishing myself by doing that again. Note that you _will_ have a problem some day, it is just a matter of time. By having all the other file systems broken out of / I never have to worry about resizing it. Except for the contents of /root, it just doesn't grow, and I have complete control of what goes in /root. Unless things work out just so I usually wind up with a decent amount of unused space in the VG. This is a good thing to keep in reserve so that you can expand one or another of the LVs. So, what I do is take my first 3390-x volume, and put two partitions on it. The first is for /, and I make that about 500MB or so. You can decide how big you want it for your systems. The second is for LVM as a PV. All other DASD volumes I only put one partition on, and those are all for LVM PVs. Note that I am not talking about application/data storage space here. This is only for the operating system. The non-OS space comes from additional DASD (or SCSI) and that goes into a separate VG from the OS. Why? See above. I remember on one red book said put /boot on /dasda with the size 512 MB. then the rest put into LVM. Can't find that book anymore. Is that right? 512MB for /boot is way too large for any practical purpose. If you're going to put / into an LV, I would only make /boot around 50-100MB. But, as I said, I wouldn't have / in an LV.

Re: what is the recommand when we do partitions during installation
Do all these people you speak of just affect / ? I don't understand the argument.. Yeah - mistakes get made. The really important data is probably not under the / LVM at all... it's in those other filesystems that I guess people don't affect? ;-) The only argument I'm really hearing is that recovery is harder.. and well, maybe. I've had clobbered non-LVM / disks before... I brought up a recovery system to fix what I could. That's what I did for an LVM / as well.. and since we have hundreds of these buggers they are all set up exactly the same way from an OS point of view and I didn't need the config info to know where things are or which disks might be the issue. (That's why conventions like 100-1FF for Linux OS volumes are nice -- you always know which disks make up an LVM) Anyway - I still say humbug. There's nothing about a non-LVM / that will protect you from people...

Re: what is the recommand when we do partitions during installation
I have and I do.. although they were/are virtual servers - not physical. And we should actually be talking about shared/RO root for this many servers instead of hundreds of separate, breakable ones if we're trying to limit the people factor..

Re: Where does games come from?
When did Marcy indicate she didn't know the purpose of these accounts? I think we all get (how could we not by now) that you think it's a bad idea to remove 'system' ids. That's a valid approach -- but it's not helpful to Marcy - who obviously disagrees (as do I). I'm glad you wouldn't be disturbed by user/accounts that you, the sysprog, deleted and finding them magically restored. I am, Marcy is - and you are not helping.

Marcy was asking for help in deleting accounts she did not know the purpose of, /and/ the system /is/ the arbiter in that these system accounts own system files which are orphaned if the system accounts are deleted. In a worst-case scenario (that's what security planning is about, right?) 1. ftp system files are orphaned by deleting the account 2. a user account re-using the uid number for the vanished ftp account is accidentally created 3.

Re: Where does games come from?
Hi Marcy - Are you issuing userdel? or editing /etc/passwd? (your reference to it makes me ask)...been awhile since I played with things like this -- but I recall /etc/shadow maybe getting resolved by 'something' and putting entries in passwd. Do the entries show up at the end of passwd? Or 'back in place'? Just thinking of clues..

Right - let's compare the MAINT user (i.e. root) with 'games' on Linux... Since when is the 'default install' something that shouldn't be changed, Jack???

Re: Where does games come from?
So? How does this explain why they reappear if removed? If I had a NOLOG guest pop backup up on my zVM system after I removed it .. I'd consider it a bug, regardless - and a security violation to boot.

Hi Marcy -- back to reality here... how did you remove the accounts? Did any actions precipate them returning? Scott p.s.
