I would remove the disk drive from ADSM, remove from the volume group,
remove the pdisk, replace the drive run cfgmgr to recreate the pdisk, add
the disk to the volume group, configure the drive on the LVM level, and add
to ADSM.

        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.
