PHKL_24268

[Randy_9]

HP sent out a notice recalling PHKL_24646 and
recommended installing/using PHKL_24268 (a
previous version). I did so and my system is hung. If I do a "swlist" of this patch, it shows up as:
"pv_curxfs, lv_resyncpv cumulative patch"
BUT SHOULD BE:
"LVM cumulative patch"
Even after un-sharing it PHKL_24268 the description for it shows it as "LVM cumulative patch", but if you run "strings" on the
PHKL_24268.depot" the description is
"pv_curxfs, lv_resyncpv cumulative patch".

Is this a case of the wrong patch being mis-identified?. My system is hung and I cannot swremove the patch (the system in single user
mode), the system justs sits there?
What is going here?

Thanks,
Randy

Did you remove patch PHKL_24646 first, before installing PHKL_24268 ?

Also, xfs in "pv_curxfs" is LVM and "lv_resyncpv" is LVM also.

Have you rebooted your machine?

Hi randy,

please read the warning from HP:
01/10/06 - This Critical Warning has been issued by HP.
- PHKL_24646 introduced behavior whereby LVM commands may hang. In most cases a reboot will clear the hang. However, in some cases, most notably with volume group activation, the hang will re-occur after the reboot.
- This behavior is also exhibited with superseding patch PHKL_25118.
- If you are already successfully using these patches then it should be safe to continue to do so (see item on Volume Group Importing below).
- If these patches have not yet been installed, before installing the patches it is recommended to perform the following check:
1. Discover the name of any boot disk for the system:
# lvlnboot -v vg00 | grep -i "Boot Disk"
/dev/dsk/c0t6d0 (52.6.0) -- Boot Disk
2. Run the following xd(1) command on any one of the boot disks:
# xd -An -tx -j0x218000 -N4 /dev/dsk/c0t6d0
3b39e3a8
If the number returned by xd(1) (0x3b39e3a8 in the above example) is 0x70000000 or greater then do NOT apply the patches.
- Volume group importing:
If you vgimport(1M) volume groups from other systems, then perform the above check on those systems as well. If the other systems fail this check then either do not apply these
patches, remove the patches from the importing system or do not vgimport(1m) their volume groups until the patches are replaced by a patch that addresses this behavior.
- If the above described check fails and an affected volume group must be imported, HP recommends removing PHKL_24646 and PHKL_25118 from all systems that exhibit this problem.
The patch should also be removed from software depots used to install patches on these systems.
- The previous LVM patch, PHKL_24268, does not exhibit this same behavior and is being re-released until a replacement patch is available. To ensure as many known issues as possible are ddressed, HP recommends that PHKL_24268 be installed after PHKL_24646 and PHKL_25118 are removed. If PHKL_24268 was installed prior to PHKL_24646 or PHKL_25118, it will automatically be restored when they are removed and it will not need to be reinstalled.

Hope that helps
