Failed Disk Drive
Not
Protected by a Hot Spare
When a array is not protected by a hot spare, if a disk drive in that array
fails, remove and replace the failed disk drive. The controller detects the
new disk drive and begins to rebuild the array.
If the controller fails to rebuild the array, check that the cables, disk
drives, and controllers are properly installed and connected. Then, if
necessary, use Adaptec Storage Manager to rebuild the array. For
instructions, refer to the Adaptec Storage Manager User’s Guide or online
Help.
Failure in Multiple Arrays Simultaneously
If there’s a disk drive failure in more than one array at the same time
(one failure per array), and the arrays have hot spares protecting them,
the controller rebuilds the arrays with these limitations:
●
A hot spare must be of equal or greater size than the failed disk drive
it’s replacing.
●
Failed disk drives are replaced with hot spares in the order in which
they failed. (The array that includes the disk drive that failed first is
rebuilt first, assuming an appropriate hot spare is available—see
bullet above.)
If there are more disk drive failures than hot spares, see
Drive Not Protected by a Hot Spare on page 67
.
If copyback is enabled, data is moved back to its original location once
the controller detects that the failed drive has been replaced. (Copyback
is an enhanced feature. See
Disk Drive Failure in a RAID 0 Array
Because RAID 0 volumes do not include redundancy, if a disk drive fails
in a RAID 0 array, the data can’t be recovered.
Correct the cause of the failure or replace the failed disk drives. Then,
restore your data (if available).
