
If copyback is not enabled, replace the failed drive with a new drive and configure the new
drive as a hot spare drive.

If copyback is enabled, replace the failed the failed drive with a new drive.
•
If the failed drive is a member of a redundant RAID array and is not configured as a hot spare
drive, replace the failed drive with a new drive. Then, the RAID array will automatically rebuild
the data.
RAID array failure
The management tool displays the RAID array status information. When a RAID array fails, the
management tool displays the RAID array status as
Degraded or Failed .
•
If the RAID array status is Degraded , examine the status of member drives, and replace the
failed drives with new drives. For more information, see " Drive failure ."
•
If the RAID array status is Failed , select the failed RAID array, and use the Force Online
function to force the RAID array to come online.

If the operation succeeds, you can use the migration function to migrate the data in the
RAID array.

If the operation fails, you must reconfigure the RAID array.
IMPORTANT:
•
The Force Online operation might modify the data in the RAID array. Evaluate whether this
operation is necessary before performing it.
•
The Force Online function is called Re-enable on an UN-HBA-1000-M2-1 storage controller
in UEFI mode.
•
The embedded RSTe RAID controller does not support the Force Online function. If the
RAID array status is Failed , reconfigure the RAID array.

parameters are consistent before and after replacement:
•
Storage controller model.
•
BIOS boot mode.
•
Storage controller firmware version.
•
Storage controller operating mode.

storage controller.
