Re: lvm
After replacing the disk you need to run
vgcfgrestore -n vg01 /dev/rdsk/cxtxdx & then backup your data using mirror or any other source.
Thanks

SolutionOtherwise good. By removing the disk from the volume group you can add a larger disk up to max pv per pv to your volume group like removing a 2GB disk and then adding a 4 GB disk to the volume group.
You could also try
Add new disk to volume group
pvmove from old disk to new disk
vgreduce old disk
do screwdriver work
Assumptions above assume old disk is still somewhat operational.

Re: lvm
Add the disk in the volume group
Do the pvmove from disk to disk
Then remove the disk from the volume group.
#pvcreate newdisk
#vgextend vgname newdisk
#pvmove olddisk newdisk
#vgreduce vgname olddisk
Note that pvmove command will fail if LV is striped.
