Automatic Rebuild
Starts and then
Fails
• You used a drive
of smaller capacity
to replace a failed
drive.
• The new drive may
be defective.
• Another drive in
the drive group
may have errors.
• Check to be sure that the re-
placement size is the proper
type/capacity for the drive group.
• If the replacement drive consis-
tently fails during the rebuild, it
may be defective. Try another
drive.
• Check drive error logs. Invoke the
utilities and select the Bad Block
option from the Tools menu to
check for bad blocks on the drive.
