Ÿ
If the state of the logical drive is critical (CRT), you
must rebuild the defunct hard disk drive promptly.
Ÿ
The replacement hard disk drive must be the same
size or larger than the failed drive.
Ÿ
If the hard disk drive being rebuilt is part of a RAID
level 0 logical drive, the RAID level 0 drive is blocked
to external access during the rebuild process.
– If you use the ServeRAID Configuration program
to initiate the rebuild process, the program
unblocks the RAID level 0 logical drive when the
rebuild process completes. If the rebuild process
is interrupted, you must restart the server to
unblock the blocked RAID level 0 logical drive.
– If you use the Administration and Monitoring
Utility program to initiate the rebuild process, you
must unblock the RAID level 0 logical drive when
the rebuild process completes. (See “Unblocking
logical drives” on page 38 for more information.)
Ÿ
Data that was stored in a RAID level 0 logical drive is
lost during the rebuild process. If you backed up the
data before the drive failed, you can restore the data
to the new drive.

Ÿ
Select New Location to assign a hard disk drive
in a new location. Use the Up Arrow (

drive that you want to use for the rebuild
operation; then, press Enter.
Information and status messages about each stage of
the rebuild process appear on the screen.
