Replacing an Internal Disk Drive CRU

Stopping a Mirrored Disk Drive Using SCF
Follow these instructions to shut down both paths to a disk drive. In this example, the
$DATA17 mirror drive is being stopped to prepare it for replacement.
If the disk drive is currently in the STARTED state, use the SCF STOP DISK command
to shut down both paths to the disk drive. Then use the STATUS DISK command to
verify that the disk is in a STOPPED state, DOWN or HARDDOWN substate:
TACL>SCF STOP $DATA17-M
->STOP $DATA17-MB
->STATUS $DATA17-*
STORAGE - Status DISK \TOYS.$DATA17-*
