Replace a failed mirrored data disk

balaji_vvv — Tue, 05 Nov 2013 21:22:03 GMT

I have data Volume group vg01 (NO OS) which has 6 disks and its mirrored. Now one of the disk in that logical volume (/dev/vg01/xx) is failed and I have to replace it. Do I need to unmirror before replacing the disk or it will be an easier process than this?

00018 /dev/dsk/c3t10d0 00018 current /dev/dsk/c6t8d0 00018 current

11803 /dev/dsk/c3t8d0 03122 current /dev/dsk/c6t9d0 03122 current

25942 /dev/dsk/c3t9d0 08580 stale /dev/dsk/c6t10d0 08580 current

I have disk c3t9d0 failed? What is the easy way of replacing disk c3t9d0?

Thanks

Do not unmirror, you may break it.

Just do

# pvchange -a n /dev/dsk/c3t9d0

to make the disk unavailable to LVM.
