Replace a failed mirrored data disk

Replace a failed mirrored data disk

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?

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

Re: Replace a failed mirrored data disk

Do not unmirror, you may break it.



Just do


# pvchange -a n /dev/dsk/c3t9d0


to make the disk unavailable to LVM.
