That's not quite how I'd do it.
If you have a free SSA slot, my preferred mechanism would be...
lspv Note which disks you've got.
Insert new disk
cfgmgr -l ssar I don't care if the new disk is a different number.
lspv See what the new one is.
migratepv hdisk17 hdiskXX
reducevg oravg hdisk17
ssaxlate -l hdisk17 To get the pdisk...
rmdev -dl hdisk17
rmdev -dl pdiskNN
Remove the defective disk
This way, you maintain the mirror at all times. It also minimises the
amount of I/O if you have LVs spanning disks.
If you're desperate to keep the disk as hdisk17, or don't have a free slot
then do it your way, but don't forget to remove the pdisk as well as the
hdisk.
