• Failed disk drives are replaced with hot spares in the order in which they failed.
(The pool that includes the disk drive that failed first is rebuilt first, assuming an
appropriate hot spare is available—see the previous bullet.)
If there are more disk drive failures than hot spares, see “Failed Disk Drive Not
Protected by a Hot Spare” on page 151.
Disk Drive Failure in a RAID 0 Pool
Because RAID 0 volumes do not include redundancy, if a disk drive fails in a RAID
0 pool, the data can’t be recovered.
Correct the cause of the failure or replace the failed disk drives. Then, restore your
data (if available).
Multiple Failures in the Same Pool
Except in RAID 6 pools, if more than one disk drive fails at the same time in the
same pool, the data can’t be recovered.
Correct the cause of the failure or replace the failed disk drives. Then, restore your
data (if available).
Note In some instances, RAID 10 and RAID 50 pools may survive multiple disk
drive failures, depending on which disk drives fail.
Removing a Failed Disk Drive’s Icon from Adaptec Storage Manager
Note You can only complete this task on disk drives that are not included in any
pool.
When a disk drive fails, it may still appear in Adaptec Storage Manager although it
is no longer available. To see an accurate representation of your IP SAN and make it
easier to monitor your disk drives, you can remove a failed disk drive from the
Physical Devices View.
In the Physical Devices View, right-click the failed disk drive, then select
Remove
failed drive
.
Rebuilding Pools
A hot-swap rebuild occurs when a controller detects that a failed disk drive in a pool
has been removed and then reinserted.
To start a hot-swap rebuild:
