Given that you're using TSM mirroring and hot-swap disk, you should not have
to shut down your server to recover. See the Admin Guide, chapter 21 topic
"Restoring Your Server Using Mirrored Volumes" - which is actually mistitled,
as it's for recovering from the failure of a mirrored volume while the server
continues running.  That is, a failure of a mirrored volume will likely cause
the mirror to "break", meaning that you'll be running with a single image.
You prep a replacement volume and then Vary it online to resume mirrored
operation.
