If you would rather do it ahead of time, and not after the fact, then for SLES10: rug list-updates -t patch | sed -e 1,4d | while read channel pipe1 patch reset do echo $patch rug patch-info $patch done The output could be further processed to get rid of lines you don't want. For SLES11, you would use zypper instead of rug, but the parameters would be the same.

YaST Online Update Patch Descriptions - how to capture for change record
I have a quandary that I need help with. When creating change records for updates I can easily provide a list of the newly installed patches via a rpm query: rpm -qa --last | grep "16 Aug" > /tmp/patches However that does not provide the details of what that patch does I can find the patch files via a find query: find /var/lib -name patch* But there is no way to correlate the patch file to the installed rpm updates as the patch files appear to all have the current date. Can anyone provide a suggestion for capturing details of the patches that were just installed to a file for inclusion in a change record? Thanks Lionel B.

I would take a look at the Shutdown actions chapter in the "Device Drivers, Features, and Commands" manual. It provides the ability to specify multiple CP commands to be executed on halt, kernel panic, power off, and reboot.

Re: vmpoff and vmhalt
How about an alert from OPERATOR to MAINT to tell (or warn) MAINT that a linuxguest has logged off? You can trap the LOGOFF in PROP and write an action routine to issue the MSG to MAINT whenever this event happens. This will even alert MAINT when the linux guest logs off even when a shutdown has not been performed. Regards, Berry. Op 14-09-10 15:46, Offer Baruch schreef: > I am not tring to alert the operator.

Re: managing rhel disk space
Funny, that's about exactly the setup we use root at a single minidisk ext3, /boot at a single minidisk ext2, and LVM for the rest, only diff is that we have included /srv in the system_vg :) and we did put /tmp an a separate minidisk as well. Just an importtant tip: When formatting the disks, use: dasdfmt -d ldl (and you don't need to fun fdasd after that) This way you can use DIAG driver for effective I/O requests, and this is what you want.
