pvdisplay

Dear Admins,

I tried to execute the following command:

#pvdisplay -v /dev/dsk/c12t2d7

The following output is displayed:

pvdisplay: Warning: couldn't query physical volume "/dev/dsk/c12t2d7":
The specified path does not correspond to physical volume attached to
this volume group
pvdisplay: Warning: couldn't query physical volume "/dev/dsk/c12t3d0":

pvdisplay: Warning: couldn't query physical volume "/dev/dsk/c13t3d5":
The specified path does not correspond to physical volume attached to

pvdisplay: Warning: couldn't query all of the physical volumes.

My Question is, why it is looking for the other disks that are not queried?

But when I tried to execute pvdisplay on the other disk, it does not look for the other disks.

#pvdisplay -v /dev/dsk/c17t9d6

pvdisplay: Couldn't find the volume group to which
physical volume "/dev/dsk/c17t9d6" belongs.
pvdisplay: Cannot display physical volume "/dev/dsk/c17t9d6".

Thanks in advance.

Hi,

PDEV is offline. The solution to your problem is to reactivate
the already activated volume group by doing:

vgchange -a y /dev/vg04

Vthiru,

It seems C13 path is not working. vgchange -a y to verify if you could activate the volume group.

run 'ioscan -fnC disk' to confirm if all the disk devices listed are still detected by the system. if they don't, that would be the reason you are getting those messages.

is this server part of any cluster?

Was this disk is disassociated from a particular vg on one node and now part of another VG on another cluster partner....

Yes Santhosh, you are right...it is part of cluster and the volume group is activiated on the other node. Is there a way that we can ignore the vg's those are currently not activated, while issuing pvdisplay command.

Thanks,
Thiru

There is no option to skip this. See man page for pvdisplay - http://www.docs.hp.com/en/B2355-90692/pvdisplay.1M.html
