Replacing an Internal Disk Drive CRU

7 After successful installation, write the logical name of the disk drive on the
label near the top of the disk drive CRU faceplate.
8 Resume operations on the replacement mirrored disk drive:
a Revive, monitor, and check the status of the disk drive using OSM,
TSM, or SCF. The revive process is automatic and will create a label
for the replacement disk:
OSM: use Start Volume action and check disk attributes ●
TSM: use the Up action and check disk attributes●
SCF commands: RESET DISK, START DISK, and STATUS
DISK
●
System and application software does not need to be restarted; the
other half of the mirrored volume has been operational during the
replacement procedure.
See Notes for Replacing an Internal Mirrored Disk Drive CRU for a
description of the automatic STOPPED, HARDDOWN when
upgrading to a disk drive of a larger capacity.
Caution: Wait until the disk is fully revived before performing the
next step to test the disk paths. The revive operation might take quite
a while — the time required depends on how much data resides on
the disk. The revive operation can also slow system performance,
especially for users of that mirrored volume.
b Test the disk paths (using the SCF SWITCH DISK; SCF PRIMARY
DISK, FORCED; and SCF STATUS DISK commands).
9 Check for (and spare) bad sectors on the replacement disk, using the SCF
INFO DISK, BAD and SCF CONTROL DISK, SPARE commands.
Caution: If possible, stop all processing on the mirrored volume before
sparing any of its sectors. The CONTROL DISK, SPARE command can cause
inconsistent data if the volume is being used when you issue the command. For this
reason, SCF asks you to confirm the request before it spares a sector.
