How to recognize we have LVM OLR (Online)

Frank de Vries — Fri, 17 Aug 2007 06:20:37 GMT

We have HP-UX 11.00 and I would like
to see if we have Online LVM (LVM OLR).

The reason we want to know that is to see if we can do a pvchange -a N pv (and skip the lvreduce/vgreduce part)à

How can I see we have this component installed?

This feature is only available for 11.11 and newer.

See text excerpted out of "When Good Disks Go Bad" and checkout the URL:

http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad.pdf

LVM OLR is delivered in two patches, one patch for the kernel and one patch for the pvchange command. The patches introduce a new option, -a, to pvchange. The -a option disables or re-enables a specified path to an LVM disk. For more information on LVM OLR, refer to the white paper LVM Online Disk Replacement (LVM OLR). Both command and kernel components are required to enable LVM OLR:

- For HP-UX 11i version 1, install patches PHKL_31216 and PHCO_30698 or their superseding patches.

- For HP-UX 11i version 2, install patches PHKL_32095 and PHCO_31709 or their superseding patches.

Consider to upgrade to at least 11.11.

So you get a supported OS version and the OLR feature.

Frank,

Further, HPUX 11.00 is already end of support from HP, so LVM OLR is not available for 11.00
