Re: PV Status: unavailabe
The disk in question is most likely offline.
It may not be assigned to the World Wide Name(WWN) of your fiber card. In that case it would be insvisible. But it was assigned and a SAN admin changed it, that would explain it.
There could be a bad disk.
Take a look:
ioscan -fnC disk
If you don't see that device claimed, its probably one of the issues above.
if its a simple disk, replace it. If it's LUN configuration than deal with that issue.

Re: PV Status: unavailabe
Hi,
Even if the disk is OK , and if the LVM headers are corrupt then also the PV status wont be available.
try #pvdisplay on the disk.
if its a mirrordisk / alternate disk then you can do a vgcfgrestore on the disk.
With Regards,
Siva.

Re: PV Status: unavailabe
Have you enabled WWN to your FC card ? Hopefully, since you can see the disk and its unavailable, it could be a security problem with zoning.
Also, do # dd if=/dev/rdsk/c23t4d3 of=/dev/null bs=64k count=100

Re: PV Status: unavailabe
pvcahnge or vgchange will not cause any demage to data. You can try pvchange but vgchange will not do anything as the VG is allready active.
Also can you post "strings /etc/lvmtab"
As vgdisplay for the VG shows both volumes to be active and status shows unavailable. pvchange should be able to fix it. Also post "bdf" output.
What is the current status of 8 LVs in the VG?
HTH,
Devender

Re: PV Status: unavailabe
# pvchange -a y /dev/dsk/c23t4d4
It will change that PV to be available state.

Re: PV Status: unavailabe
LVM OLR should be available to use the pvchange -a Y command.
Both command and kernel components are required to enable LVM OLR: ├в ┬в For HP-UX 11i version 1, install patches PHKL_31216 and PHCO_30698 or their superseding patches. ├в ┬в For HP-UX 11i version 2, install patches PHKL_32095 and PHCO_31709 or their superseding patches.
Rgds,
Ajit
