hpux 11.11 - Dump Lvol Bad disk

[cpdla]

Hi I have an L2000 running 11.11

VG00 has 4 disks

one of the disks c2t0d0 is only used by dump lvol and not mirrored

c2t0d0 is reporting errors and needs to be replaced.

My plan is:

#pvchange -a N /dev/dsk/c2t0d0 

SWAP THE DISK

#vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t0d0 

#pvchange -a y /dev/dsk/c2t0d0 

#vgchange -a y /dev/vg00

#lvlnboot -R

Thanks in advance for your help

After you swap the disk, I would do a 'ioscan -fnC disk' and a 'diskinfo /dev/rdsk/c2t0d0' to make sure the disk is visible and good.

Other than that, I think your steps look good.

Because the disk is not mirrored and not already dead, the system will likely crash if you remove the disk online.

I would shutdown, replace the disk, boot into LVM maintenance mode, do the vgcfgrestore and then boot again.
