• From Service Aids run diagnostics to all the
disk drives that are listed as rejected.
• Run the Certify service aid (see "Certify Disk
Service Aid" on page 120) to all the disk drives
that are listed as rejected.
If no problems occur on any disk drive, go to step
25. Otherwise, continue with this procedure.
• Go to "Disk Drive Assembly (HDA) Removal
and Replacement" on page 164 to exchange
the disk drive.
• Referring to the displayed instructions, select a
disk from the list of array candidate disk drives,
and add that disk drive to the array that is in
the Exposed state.
The array changes its state from the Exposed
state, and parity is rebuilt.
End of procedure

Go to step 45 to add the disk drives to the group of
disk drives that are available for use by the RAID
manager.

Does the current diagnostics or disk service aid
indicate an open loop
YES NO

Note: A disk drive that is listed as rejected is not
necessarily defective. For example, the array
might have rejected the disk drive because a
power problem, or an SSA link problem, caused
that drive to become temporarily unavailable.
Under such conditions, the disk drive can be
reused.
The dotted line (-----) in disk service aids indicates
that a link in one of the loops is broken.
