I need to find out the hard disk which has problems and the volume group in which it is located.

/dev/dsk/c1t3d0

[candlejack]

Please run the following as root and see if any disks are marked as "NOT CLAIMED"

ioscan -fnC disk

[Waqar Razi]

Can u give me details what was the problem because that disk seems to be CLAIMED in ioscan -funC disk.

[Tim Nelson]

The drive reset. Powered off then back on..

It is either failing, or has a bad connections.

Monitor. If it never fails again then it was just gas. If it fails again then replace it.

[OldSchool]

actually, Tim told you. If you note, the fault recovered, so all you can go on is the log

"Aug 11 14:48:17 WARRIOR vmunix: LVM: VG 1 : PV 2 (device 0x1f013000) is POWERFAILED

Hi,
I think Tim is right, but if you have some doubt, then you can use "dd" command to clarify it. . .

dd if=/dev/rdsk/c1t3d0 of=/dev/null bs=64k

Salam Waqar,

I think you are experiencing hardware errors on a disk.

Test the disk with dd command.

# dd if=/dev/dsk/cxtxdx of=/dev/null bs=64 count=1000

If successful, the results of this command will look similar to:

100+0 records in
100+0 records out

further you can check with diskinfo command.

#diskinfo /dev/rdsk/cxtxdx
check for errors.
