Replacing Internal Disk(s)
If an internal SCSI disk problem occurs, take the following steps to replace the
disk:

Execute [Remove half disk] of [=>RAID] of ftdiskadm to disconnect the
RAID of the disk to be specified with the slot number and disconnect the
disk from the system.
2.
Remove the disk from the system, and insert a new disk.
3.
