Silencing the Alarm
If your Adaptec RAID controller includes an alarm, the alarm will
sound when an error occurs. To silence the alarm, use Adaptec Storage
Manager (see
Managing Your Storage Space on page 60
.)
Recovering from a Disk Drive Failure
This section explains how to recover when a disk drive fails:
●
If the array was protected by a hot spare (see
●
If the array was not protected by a hot spare (see
).
●
If there is a disk drive failure in more than one array simultaneously
(see
●
●
If multiple disk drives fail within the same array (see
Note:
Adaptec Storage Manager uses the term arrays when referring to
Failed Disk Drive Protected by a Hot Spare
When an array is protected by a hot spare, if a disk drive in that array
fails the hot spare is automatically incorporated into the array and takes
over for the failed drive.
To recover from the failure:
1
Remove and replace the failed disk drive (following manufacturer’s
instructions).
2
If copyback is not enabled—In Adaptec Storage Manager, remove the
‘hot spare’ designation from the original hot spare (the disk drive
that was built into the array). Then, designate a new hot spare to
protect the arrays on that controller.
If copyback is enabled—Data is automatically moved back to its
original location once the controller detects that the failed drive has
been replaced. No action is required.
Note:
Copyback is an enhanced feature. See
