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.
