MEMO MOVINGON
Just a quick note to let everyone here know that I've had a job change, but not a career change. After 15 years with Sirius (ok, combined time with VM Assist, Sytek Services, DSG, SESG, and finally Sirius), I've taken a VM system programmer job with Visa here in the Denver area. I'll still be doing VM, and encouraging more Linux on Z, but no more TSA gropings.

Re: Hipersockets broke Ethernet?
RHEL has an error where if you use system-config-network on a layer 2 interface it forgets that it was layer 2. Reported a year ago as Bug 809534 - system-config-network ignores option field. No fix.

SLES11 SP1 - Have you seen this?
Hi... I have a customer running SLES11 SP1 and a layer 2 Vswitch. When we did the initial install, all went well, and all the clones behaved as expected. They did another from scratch install the other day and it seemed to go well. But when they cloned it, they started to have network trouble, and it ended up that they couldn't have their new master Linux and a clone of that up at the same time -- even though they had different IPs. The problem turned out to be that for some reason the new master (and therefore it's clone) had a hardcoded MAC address (LLADDR=) in the network definition. So even though they had different IPs, they were trying to use the same MAC address. Removing the LLADDR= fixed the problem and both were assigned dynamic MAC addresses by the Vswitch. But the question was posed -- Why was it different than the first install? I wasn't there for the 2nd install, but they say they followed the same steps and chose the same options. And there was no LAYER2=1 in the network setup files. Anyone have any thoughts on what they might have done differently to cause the MAC address to become fixed on the Linux side? Thanks for any thoughts..

With cio_ignore you can modify the device blacklist. The reason you have to remove a device from the blacklist before you can use it is that you have added the device to the blacklist in the first place. So either you did a cio_ignore --add earlier or you have set the cio_ignore kernel parameter (most likely the latter). If you want linux to use all available device simply remove the cio_ignore kernel parameter.

OSI Layer 2/3 mismatch?
Hi all I must be missing something... Customer has a VM 6.1 system (RSU 1101 + z114 PTFs) and SLES11 SP1 guests. Initially the guest was on a Layer3 Vswitch - no problem. They needed to change to go to Layer2 so they could have guests on different VLANs - but still have the Linuxes be Layer3. We: - Updated the IP info on the Llnuxes and shut them down and logged off. - Deleted (DETach) the old Layer3 Vswitch. - Networking changed the real switch port to trunk mode - We changed the TCPIP stack to Layer2 and it's VLAN - all ok.. - We redefined the Vswitch as: DEFINE VSWITCH VSWITCH2 RDEV E203 ETH VLAN 999 NAT 999 (Default PORTTYPE ACCESS) - Regranted the user as: SET VSWITCH VSWITCH2 GRANT LXTECH VLAN 301 All looks good in the queries But when we boot the Linux, we can see qeth try to register layer3, but we get: The qeth device is not configured for the OSI layer required by z/VM We've double checked our definitions and even bounced the system.

Re: Limited AD Login Authentication

To find the group's SID from the linux system that has already joined the domain, type wbinfo --name-to-sid='AD\it technical support' (where the AD\is the AD domain name) which will produce something that looks like: S-1-5-21-908518461-770907536-2395883247-1125 Domain Group (2) 3) Edit /etc/pam.d./common-auth (really a link to /etc/pam.d/common-auth-pc) 4) Add require_membership_of=AD\\linuxadmins (if group's name has no spaces) or require_membership_of=S-1-5-21-908518461-770907536-2395883247-1125 (if group's name has spaces) to the end of authrequired pam_winbind.so use_first_pass (Again the AD\ is the name of the AD domain.) 5) Save /etc/pam.d./common-auth 6) rcwinbind restart (not sure if this is needed but it does not hurt) That should allow any user in the selected group to login to the Linux system, but deny all other AD users.

Limited AD Login Authentication

Re: RH 5.5 Local TOD...
Yes, but if you select that the system/hardware clock is on LOCAL time, (install time or later) RH seems to ignore that still uses the timezone offset for whatever timezone you specified.

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* .

There's been some discussion recently about an Anaconda bug that show up if you have only 1 processor defined or exactly 2GB of storage defined. What's your system look like? When installing to a z/VM guest or LPAR that is configured with 1 CPU and/or less than 2 GB storage (memory), the installer will prompt for the network configuration, regardless of whether these parameters appear in the PARM or CONF files. This is due to an unexpected side effect of a kernel change in RHEL 5.4, and will be fixed in the RHEL 5.5 installer. There are multiple ways to workaround this issue: First, define at least 2 CPUs to the LPAR or z/VM guest. Note that if running under z/VM, defining an additional CPU does not require an additional physical IFL. If an additional CPU cannot be defined, the second workaround is to define at least 2 GB storage (memory) to this guest or LPAR. Note that under z/VM, this does not require additional physical storage. If neither of these workarounds are possible, customers can contact Red Hat support to obtain an intermediate kernel fix before RHEL 5.5 is released. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- Lee Stewart, Senior SE Sirius Computer Solutions Phone: (303) 996-7122 Email: lee.stew...@siriuscom.com Web: www.siriuscom.com -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

It's divided into 6 file systems on 6 different volume groups. (Not a DB, but just files). We did adjust the boot time interval of fsck so that all 6 don't get fsck'd on the same startup. Takes about 10 minutes on a file system at boot time (and I don't know if that is because of the size or the number of files). I don't think 8TB would be a problem. I'm not sure I'd put it all in the same volume group though. There probably isn't much of a need to, though, with a DB. Marcy This message may contain confidential and/or privileged information.

Merge /opt/IBM1 and /opt/IBM2 into an LVM with all the space of the mod 9 + the mod 27, in the filetree as /opt/IBM1. At first look, it looks like they can be merged with no overlap. BUT, two of the directories in /opt/IBM2 (the one that's going away) are WebSphere instances, both with lots of hardcoded instances of /opt/IBM2... IF (big if) they will merge without overlap, can I put the new LVM online at /opt/IBM1 (where all the stuff that was on /opt/IBM1 will continue to run). And put a synlink in /opt as /opt/IBM2 that points to /opt/IBM1 (so all the stuff that was in /opt/IBM2 will also continue to run.

WWPNs and LUNs displayed in the Yast Zfcp panel after a GET_WWPNs or
GET_LUNs. As you mention, the zfcp_san_disc script runs san_disc and is
looking for Storage:
PORT_LIST=`san_disc -a $ADAPTER -V -c PORT_LIST`:
WWPN_LIST=`echo $PORT_LIST | awk '$6 ~ /Storage/ {print $2}' | sort -u`
While san_disc returns :
# san_disc -a 1 -V -c PORT_LIST

Linux FCP via an SVC...

Please respond to
Linux on 390 Port
linux-...@vm.mar
IST.EDU
Is anyone using Linux on Z accessing an FCP via an SVC (SAN Volume
Controller)? If so, do you see the WWPNs and LUNs displayed in the
Yast Zfcp panel after a GET_WWPNs or GET_LUNs?
As it trickles down it ends up in zfcp_san_disc. It skips any WWPN
that reports any type but Storage. Our SVC is returning a type of
Multi-function device, therefore the WWPNs aren't showing up in the
list and have to be entered manually..
Is it the SVC that should be saying Storage? Or is it zfcp_san_disc
that should also be accepting Multi-function device??
Thoughts?

LPAR (no VM) DASD migration
Hi all, We are migrating Linux CKD DASD to a new DS8100. We have two bare-metal (LPAR) linux server's running. (no z/VM). One is SLES8 and one is SLES10. For the SLES8, I plan to: 1. vi /etc/zipl.conf and change the DASD= to the new devices 2. zipl 3. mkinitrd 4. shutdown 5. migrate dasd 6. startup sles8 server (Does that look OK?) But for the SLES10 system, we are not using DASD= in zipl.conf How do I make the device numbering changes for SLES10 ? (I know that I can still use zipl.conf dasd= and I think it will use that...but not sure if that's the recommended way)...

Re: Striped LVM max size
I follow that logic. Since you can't choose 9 (in the SLES10 drop down), 5 works. Fewer than the as many stripes as you have volumes recommendation... But it still leaves my basic question -- how do you know or plan for what the max size you can use is? When we first set it up 45 mod 9s, 306GB, with 8 stripes we had to hunt and peck all the way down to 275GB...So 31GB went into the stripes. If I wanted a 300GB LVM, how do I know how much raw space I need? Thanks, Lee Mark Perry wrote: Lee Stewart wrote: SNIP For example, doing an LVM with 45 mod 9s. Round numbers math gives me 6.8GB/volume x 45 volumes = 306GB. That's close to what Max gives. But what's the number with 8 stripes? Hello Lee, The idea is to put each of the specified stripes on a different DASD. I have always used a number of stripes that was a factor of the number of DASD in the VG. So for your example of 45 DASD that would mean using a number of stripes of either 9 or 5. Also I have always added extra DASD to the VG pool in multiples of the number of stripes, in the above example that would mean adding either 9 or 5 DASD at a time. If you do not do as I suggest, then you can end up with more stripes on one or more DASD than on others. This would defeat the purpose of using stripes, which is to spread the I/O load evenly across multiple DASD. If you want to use a number of stripes of 8, then either put 48 DASD in your VG pool or reduce to 40. 48 has more factors, so with 48 DASD in the VG you could choose a number of stripes from 2,3,4,6,8,12,16,24. mark -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- Lee Stewart, Senior SE Sirius Computer Solutions Phone: (303) 798-2954 Fax: (720) 228-2321 Email: [EMAIL PROTECTED] Web: www.siriuscom.com -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Striped LVM max size
Hi all, When creating an striped LVM, how can you tell the max size you can create? If you have one stripe, there's the Max option on the LVM screen (SLES10) which will fill in the max size of the LVM. With more than one stripe, the max option goes away and some portion of the space is used in the striping. But how much? So far the best way I've found is to use Max to get a starting point, then blank out the space, set my stripes, and go back and fill in a little less each time till LVM will take it. For example, doing an LVM with 45 mod 9s. Round numbers math gives me 6.8GB/volume x 45 volumes = 306GB. That's close to what Max gives. But what's the number with 8 stripes? How can you tell ahead of time?

SLES9 Install Strangeness
Hi all... I've done this dozens (hundreds?) of times, and I've never seen this... Maybe I'm blurry-headed from looking at it too close, maybe I'm missing something obvious, but... This is the first Linux at a new site. Brand new VM (w/ a Vswitch)... Downloading the bootstrap files goes fine. IPLing them goes fine all the way through the install prompts to where it says to connect via ssh and run yast. And even logging on to the Putty/ssh session goes fine. But when I invoke yast on the Putty session to I get: Unpacked extension disk... umount: /y2update: not mounted umount: /var/adm/mount: not mounted inst-sys:~ # I never get the full screen curses menues, and when it drops back to the inst-sys prompt, I also get a Putty pop-up saying Server unexpectedly closed network connection. Over on the 3270 session I see: sshd 243: Received signal 15; terminating *** An error occurred during the installation. We initially had some network issues, so tonight I was over in the machine room to eliminate the questionable switch.. No change. Then I started looking at my virtual machine. Everything seems fine - 512M, NIC, MDISK, all just as I'd expect. And to be sure, I even tried running it with 1GB of storage... Same.. So I spent the time and downloaded new ISO images thinking some airport x-ray got too close. Same.. However the new ISOs included the updated SP3 CDs (...-CD1a.iso etc.). And they did kick out a little more info, though not much help... On the Putty session I now also see: /usr/lib/YaST2/bin/YaST2: line 373: 1357 Illegal instruction y2base $modulename $moduleargs qt $y2qt_args And on the 3270 it also shows: User process fault: interruption code 0x20001 Then shows the PSW, regs, etc... I did find one similar post on the web, but he was trying to use auto-yast and a large parm file. I have just the single record parmfile straight from the dist CDs. (And no one ever answered him.) And I'd like to say I can rule out the network, but... Is it something dumb I've overlooked being too familiar? Something anyone else has seen? Thanks for any thoughts...

Hi all... If I understand right, there is no way on SLES10 to do an install similar to SLES9's Minimal graphical system (without KDE) unless you do it manually, right? If so, has anyone produced a list of all those unneeded packages? Or is it up to each site to try it on their own? (Sure the first 5-10 are easy.

Re: LVM Stripes

The other has approximately 300 primary mail users and is part of a 3 server mail cluster. This particular server hangs approximately every 2 - 3 weeks. The server does not allow notes clients, notes admin or SSH connections during this time. The only way to regain control is to force the VM to restart.

Re: protocol converter?
Isn't the better/full answer to get IBM to support the Integrated ASCII Console on the HMC? Lee McKown, John wrote: I've read a lot here about people wanting to use vi or some other application which is full screen from the Linux console. The reply is always that the Linux console cannot be used in the manner. Now, back in the deep, dark past, I remember a product that we had on VM/370 (yes, that long ago!). This was a software protocol converter which allowed a start-stop or async terminal, such as a VT-100, to logon to a service machine (via NCP/NTO). This service machine would then use VM's LDC (?) to create a 3270 session and it would convert the 3270 control sequences to VT-100 control sequences. I'm curious if something similar could be done for Linux. That is, have the Linux console be defined as CONMODE 3270 in the guest's VM directory. Now, have a device driver which could do a reverse 3270 protocol conversion. That is, make the 3270 appear as a VT-100 (or subset). The application would use VT-100 escape sequences. The device driver would convert these to 3270. I will grant that emulating the full duplex ability of the VT-100 and control keys would make this difficult. But z/OS DIDOCS emulates a full duplex capability on a 3270, so it should be possible. Well, to those who are smart enuf (I'm not!).

Re: Linux as a hipersocket router...
Thanks to Alan, David and Mark... Our router is now working...David was right, to try the simpler method, and all we needed turned on was IP forwarding. And Mark hit another nail on the head when he pointed out some flawed addressing and routing. The biggest thing was the routing on the MVS side of the hipersocket was setup wrong. So even when the VM/Linux side was working right, MVS never answered because of the bad routing there. (And I apologize to all for some cut-n-paste in the original notes that muddied the water a bit.) Thanks again to all...

Re: Linux as a hipersocket router...
As David Boyes said, it should be simple. And it is if all is setup right... In a nutshell: - turn on IP forwarding in the router - add a route on z/OS to the guest LAN subnet via the router IP on the hipersocket - add a route on the Linux guests to the hipersocket subnet via the router IP on the guest LAN We had one subnet allotted to us for the hipersocket connections - 192.168.11.0. The normal subnet mask for that would be 255.255.255.0. But we really needed two networks - one using a hipersocket between z/OS and our Linux router, and a second network on a guest LAN connecting the Linux router to the Linux farm. So we logically split the 192.168.11.0 network into two - 192.168.11.0 and 192.168.11.128, both now using a subnet mask of 255.255.255.128 (or /25 if you use that notation). On z/OS: Home (for the hipersocket connection) 192.168.11.10 DEVICE IUTIQDE0 MPCIPA LINK HIPERLE0 IPAQIDIO IUTIQDE0 BEGINROUTES ;ROUTE Dest/Mask(#bits) Gateway Linkname MTU Pktsize ROUTE 10.0.0.0/8=OSD1 MTU 1492 ROUTE 10.0.0.0/8=OSD2 MTU 1492 ROUTE 192.168.11.0/25 =HIPERLE0 MTU 8192 ROUTE 192.168.11.128/25 192.168.11.2 HIPERLE0 MTU 8192 ROUTE DEFAULT 10.171.72.1 OSD1 MTU 1492 ENDROUTES On the Linux Router: eth0 - to the Vswitch for ssh access etc. eth1 (guest LAN) - 192.168.11.129 mask 255.255.255.128 hsi0 (hipersocket)- 192.168.11.2 mask 255.255.255.128 IP forwarding ON On the Linux Guests: eth0 - to the Vswitch for ssh access etc. eth1 (guest LAN) - 192.168.11.130 mask 255.255.255.128 add an extra route for 192.168.11.0 mask 255.255.255.128 gateway 192.168.11.129 Then it's just add Linux guests to the guest LAN and they all have z/OS access... Yes, the routing is a bit slower than a direct hipersocket connection, but it's lots faster than waiting for an IOCP change and POR... Our big killer that took forever to find was the z/OS routing. It was supposed to be right according to the z/OS guys. Once we got that fixed the rest flew... If that leaves more questions, drop me a note and I'll try to explain.

Re: Linux as a hipersocket router...
OK, I went back to the device drivers book only. (Same steps as the SHARE presentation).. I do have a layer3 QDIO guest LAN.. For a router or the Hipersocket Network Concentrator thhe book says to issue the following to the hipersocket device: echo primary_connector /sys/bus/ccwgroup/drivers/qeth/0.0.a1c0/route4 I do and I get (on the 3270 console): qeth: Error (0xe012) while setting routing type on hsi0. Type set to 'no router' The book also says to issue the following to the OSA (the QDIO guest LAN in my setup): echo multicast_router /sys/bus/ccwgroup/drivers/qeth/0.0.a1c4/route4 and I get: qeth: Error (0xe012) while setting routing type on hsi0. Type set to 'no router' In trying other things, the hsi0 won't accept primary or secondary router or connector, but it will accept multicast_router. And the eth1 guest LAN interface will accept primary_router. But that's backwards from what the book asks for... But still can't ping across the router, the same after the start_hsnc.sh Any further thoughts? Has anyone sucessfully done something similar, or even the Hipersocket Network Concentrator (since the qeth driver won't take the commands from the book)?

It has a hipersocket defined with IP address 192.168.11.10 and a mask of 255.255.255.0. We have the 192.168.11.0 subnet to use. And to split subnets across the router, we're using 192.168.11.2 for the z/OS hipersocket link with a mask of 255.255.255.128 (192.168.11.1-192.168.11.127). Then we have a qeth NIC attached to the guest LAN with an address of 192.168.11.129 and a mask of 255.255.255.128 (192.168.11.129-192.168.11.254). For this to work you will have to use the Linux HiperSocket Network Concentrator configuration (see the device driver book). That also means you will have to use a TYPE QDIO IP (layer 3) Guest LAN for the other side. Can anyone see what I've missed or where I've gone wrong? Thanks for any advice and counsel... Try again using the instructions in the device driver book (rather than the SHARE presentation) and see if that works better. The book also has example configurations.
