Hi,
Follow this:
1.- First of all you should backup your VG and the structure (vgcfgbackup).
2.- Test your disk with diskinfo /dev/rdsk/cXtXdX and dd if=/dev/dsk/cXtXdX of=dev/null and ioscan -fnCdisk (if it is not answering then it is definitely failed)
3.- Shutdown your system
4.- Replace the disk
5.- Boot to single user
6.- Execute vgcfgrestore /dev/vgXX /dev/dsk/cXtXdX
7.- Activate the VG
8.- Probably, if you had information spread all along the disks you should restore the data.
I hope it helps.
Cristian.

Hi all,
I have encountered the issue with the hard disk, the disk is failed and need to replace by the new one.
As my understanding, this is just to take out the failed disk and insert the new ones, and that's all.

NAME
mkdevmaps - make device_maps entries
SYNOPSIS
/usr/sbin/mkdevmaps
DESCRIPTION
The mkdevmaps command writes to standard out a set of device_maps(4) entries describing the system's frame buffer, audio, and removable

tape /dev/rst*, /dev/nrst*, /dev/rmt/...
floppy /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
