♦
If a spare drive exists in the same logical drive, the
controller will automatically mount the spare drive and
start data rebuilding in the background.
♦
Depending on the design of the system external to the
controller, it may be possible to remove a defective drive
and replace it with a new drive without shutting down the
system (hot-swapping). Alternatively, the system can be
shut down at a convenient time and the failed drive

to remove a defective drive and replace it with a new drive
without shutting down the system (hot-swapping).
Alternatively, the system can be shut down at a convenient
time and the failed drive replaced.
♦
If the replacement drive is installed on the same channel
and SCSI ID, you can then proceed with data rebuilding.
♦
If the replacement drive is installed on a different channel
or SCSI ID, you need to scan in the new drive first then
assign it as a spare drive of the logical drive. Data
rebuilding will have to be manually initiated.
IMPORTANT: Although the RAID system provides
uninterrupted disk access even after a disk failure, do not
leave a failed drive unattended to. Without replacement, the
system will not survive a failure of a second drive on the
