Re: Timezone change.
On the z/OS side, we had some issues that we raised to IBM via an ETR. We ended up adding a line to CEECOPT (LE Options) that specified the month, week and time to change the clocks (US East Coast time was a default that we used (probably without even realizing it). Certainly, the C localtime calls that we do worked correctly with the added line to CEECOPT. An IBM APAR gave us some issues as we currently have some of our systems at different PTF levels. Is there a similar file to change under z/VM?

We patched all of our z/systems and when we rebooted some of them defaulted back to UTC and the time was showing off. I reset them via yast to reflect localtime and everything went well after IPL. The following (DST weekend) I patched all my systems, made sure they were reflecting localtime and now after IPL they are showing up on UTC time, but in yast their are showing up as localtime. Any ideas why some of my guests (across different lpars) boot in UTC even though they show localtime and why some of my guests never had a problem with this and always ipl into the correct hardware clock mode? Anyone else experience this problem? Could it have something to do with VM and how the guest is picking up its time on ipl?

can a max file size be set when using lvm
Good day, Back ground; Today on non z/Linux systems our install sets a max file size for / , /opt, /tmp, /var,/usr this is done at install time by setting the partition size and then the mount point to that partition. The minimum size real hard drive is 36g. The problem; On our z/Linux systems we have decided to go with only ECKD disks and all mod3's This gives us many 2.3g drives. If in the install I set say 10 2.3g disks into one lvm (giving me a 23g drive). Setting the Mount point to / Is there a way to set a limit size for say /var to only be able to grow as big as 4.0g or /tmp to a max of 2.0g ? other: If the best answer would be to set our ECKD disk to bigger than mod3 ( say mod27 or 54 ) so that the disk could be the right size and not do lvm any feedback that would support that would help But if it can be done using lvm that is the way we would like to go ..

Re: can a max file size be set when using lvm
The problem with a layout like this is the granularity. With the root being one large filesystem, and containing lots of other directories, you leave yourself open to possible failures that can be avoided if you use LVM and break up this filesystem. The /var and /tmp directories can consume space very quickly, leaving you with a root filesystem that is completely full without much notice. If these are broken off into their own filesystems, they're much more controlled, and can be more easily watched and problems diagnosed quicker. The /home filesystem has the same problem as the other two; A runaway task owned by some user can fill the filesystem quickly, leaving you... Surprised. Another problem comes if the guest needs to be re-imaged. Having /home in with the root filesystem means that you can't just scratch that filesystem and start over. You have to spend time moving data out, and then later back in. While you can allocate several smaller minidisks via zVM, you have to be able to maintain the structure. It's somewhat of a problem to expand a minidisk, while LVM allocations can be expanded and contracted very quickly, and additional minidisks can be added to the volume group to address future needs. Our current standard is to allocate two 3390 mod 9 equivalent minidisks to a new guest. The first becomes volume group vg_system, and is broken down into /tmp (500 mb), /var (2.5 gb), swap (1 gb) and the root directory (whatever's left). The second mod 9 becomes vg_local, and has /home (2 gb) and /opt (5.4 gb). We have most of our non-distribution software installed in the /opt path. If we need to move the users to another guest, we can move the second mod 9 to the other system, and they'd still have all their data and applications. If the users run out of room, it's fairly simple to add another volume to the volume group and expand the directory needing space. It's also fairly easy to create another logical volume in the group and add another path and filesystem when needed. We haven't really seen any crashes due to root being in LVM. Where we have had trouble, we'd have had the same problem with a flat filesystem as well. Logging in twice comes to mind... Note too that we set up our Intel-based Linux boxes in much the same way. In this way, we can walk up to any box and have some reasonable expectations. On logrotate: This tool does a great job... For what it works with. An example where if fails to fit is sar data and reports, which already have a timestamp in the name. logrotate doesn't handle files in that format, so you end up having to come up with another way to control them. The rmf collector is another one that has this problem, except in the /opt path. Printing and e-mail can fill /var if there is some problem with a task creating files in these spaces. /var can still fill up, despite your best efforts to control it. This layout has worked very well for us... Your mileage may vary. -- .~.Robert P.

Re: NIS on Linux
Don't forget to go back and start it again once you have things stablized. Without nscd, every request will cause a trip back to the server for data. Nscd's purpose is to shortcut these requests, speading up your system and cutting down on your network traffic. It is surprising just how much traffic is generated by shutting down nscd. -- .~.Robert P.

With the root being one large filesystem, and containing lots of other directories, you leave yourself open to possible failures that can be avoided if you use LVM and break up this filesystem. The /var and /tmp directories can consume space very quickly, leaving you with a root filesystem that is completely full without much notice. If these are broken off into their own filesystems, they're much more controlled, and can be more easily watched and problems diagnosed quicker. The /home filesystem has the same problem as the other two; A runaway task owned by some user can fill the filesystem quickly, leaving you... Surprised. Another problem comes if the guest needs to be re-imaged. Having /home in with the root filesystem means that you can't just scratch that filesystem and start over. You have to spend time moving data out, and then later back in. While you can allocate several smaller minidisks via zVM, you have to be able to maintain the structure. It's somewhat of a problem to expand a minidisk, while LVM allocations can be expanded and contracted very quickly, and additional minidisks can be added to the volume group to address future needs. Our current standard is to allocate two 3390 mod 9 equivalent minidisks to a new guest. The first becomes volume group vg_system, and is broken down into /tmp (500 mb), /var (2.5 gb), swap (1 gb) and the root directory (whatever's left). The second mod 9 becomes vg_local, and has /home (2 gb) and /opt (5.4 gb). We have most of our non-distribution software installed in the /opt path. If we need to move the users to another guest, we can move the second mod 9 to the other system, and they'd still have all their data and applications. If the users run out of room, it's fairly simple to add another volume to the volume group and expand the directory needing space. It's also fairly easy to create another logical volume in the group and add another path and filesystem when needed. We haven't really seen any crashes due to root being in LVM. Where we have had trouble, we'd have had the same problem with a flat filesystem as well. Logging in twice comes to mind... Note too that we set up our Intel-based Linux boxes in much the same way. In this way, we can walk up to any box and have some reasonable expectations. On logrotate: This tool does a great job... For what it works with. An example where if fails to fit is sar data and reports, which already have a timestamp in the name. logrotate doesn't handle files in that format, so you end up having to come up with another way to control them. The rmf collector is another one that has this problem, except in the /opt path. Printing and e-mail can fill /var if there is some problem with a task creating files in these spaces. /var can still fill up, despite your best efforts to control it. This layout has worked very well for us... Your mileage may vary. -- .~.Robert P.

Re: can a max file size be set when using lvm
The problem with a layout like this is the granularity. OK, what Robert said. I am not in a position of having to maintain any real production servers. So I often just clone a new one when I need one. For the /home/ issue, I agree, if you have a set of users. In the latest two cookbooks we describe a traveling /home/ that uses NFS and automount. But again, I don't have it in production, so it's just a starting point. It's good to hear that you are finding LVM with a root file system stable. In the past, others on the list have reconsidered such an approach. If we need to move the users to another guest, we can move the second mod 9 to the other system, and they'd still have all their data and applications. That's pretty cool too - separating the system from the data.

A logical volume will not extend beyond its allocated size, even if there is free space in the volume group.

With the root being one large filesystem, and containing lots of other directories, you leave yourself open to possible failures that can be avoided if you use LVM and break up this filesystem. The /var and /tmp directories can consume space very quickly, leaving you with a root filesystem that is completely full without much notice. If these are broken off into their own filesystems, they're much more controlled, and can be more easily watched and problems diagnosed quicker. The /home filesystem has the same problem as the other two; A runaway task owned by some user can fill the filesystem quickly, leaving you... Surprised. Another problem comes if the guest needs to be re-imaged. Having /home in with the root filesystem means that you can't just scratch that filesystem and start over. You have to spend time moving data out, and then later back in. While you can allocate several smaller minidisks via zVM, you have to be able to maintain the structure. It's somewhat of a problem to expand a minidisk, while LVM allocations can be expanded and contracted very quickly, and additional minidisks can be added to the volume group to address future needs. Our current standard is to allocate two 3390 mod 9 equivalent minidisks to a new guest. The first becomes volume group vg_system, and is broken down into /tmp (500 mb), /var (2.5 gb), swap (1 gb) and the root directory (whatever's left). The second mod 9 becomes vg_local, and has /home (2 gb) and /opt (5.4 gb). We have most of our non-distribution software installed in the /opt path. If we need to move the users to another guest, we can move the second mod 9 to the other system, and they'd still have all their data and applications. If the users run out of room, it's fairly simple to add another volume to the volume group and expand the directory needing space. It's also fairly easy to create another logical volume in the group and add another path and filesystem when needed. We haven't really seen any crashes due to root being in LVM. Where we have had trouble, we'd have had the same problem with a flat filesystem as well. Logging in twice comes to mind... Note too that we set up our Intel-based Linux boxes in much the same way. In this way, we can walk up to any box and have some reasonable expectations. On logrotate: This tool does a great job... For what it works with. An example where if fails to fit is sar data and reports, which already have a timestamp in the name. logrotate doesn't handle files in that format, so you end up having to come up with another way to control them. The rmf collector is another one that has this problem, except in the /opt path. Printing and e-mail can fill /var if there is some problem with a task creating files in these spaces. /var can still fill up, despite your best efforts to control it. This layout has worked very well for us... Your mileage may vary. -- .~.Robert P.

vmcp commands Virtualization Cookbook
I am trying to work through the new revision of the Virtualization Cookbook and SLES 10 and have found that I'm having trouble with a couple of commands when invoking vmcp. On page 224 of the cookbook, it talks about four commands that are sent to z/VM; two of which don't appear to work correctly for me. Namely they are: vmcp query proc vmcp query nss all map All of which return: HCPCFC003E Invalid option - PROC Error: non-zero CP response for command 'Q PROC': #3 And: HCPCFC003E Invalid option - NSS Error: non-zero CP response for command 'QUERY NSS ALL MAP': #3 A third command, which doesn't return an error, vmcp query files, returns no data to speak of. It simply returns the headings of the output: FILES: NO RDR, NO PRT, NO PUN Does anyone know why this might be? It's odd that the command vmcp q cplevel returns exactly what I expected it to.

Indeed, the general strategy of CP commands is to hide the powerful commands and options and for general users to act like the command does not exist. This sometimes causes a problem when a general user works on a more-than-G userid (Why does DEF STOR not work for me?). It used to be easy to purge all spool files in the system while you meant to purge your own. The syntax now is such that most of us cannot get it right the first 3 times to purge their own... Some of us believe this is the proper privilege class for a Linux guest, and that VM systems administration should not be delegated (intended or not) to someone who happens to have root access on the Linux server. Especially because some commands just work differently when you have more than class G. See http://publib-b.boulder.ibm.com/abstracts/redp3870.html Many of the CP commands beyond class G have a global impact and you want someone to oversee the implications. Like when you create NSS files there may be implications for backup and restore, or disaster fallback. And if you happen to be a person having both roles, then you might still enjoy being able to do your VM work without the need to have a Linux system running (like in repair situation).
