WD ARRAY MANAGEMENT SETUP
CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 49
USER MANUAL
Array Critical
When a disk drive fails on a fault-tolerant array (RAID 1) for any reason, the Array goes
Critical. The array can still read and write data but fault tolerance has been lost.
An Array Critical
icon displays in Tree View and the alarm (if enabled) beeps quickly to
call your attention to the condition.
Your first action is to identify which disk drive has failed.
1. Click on the Controller
icon to expand it.
2. Click on the Array Critical
icon to expand it.
3. Observe and compare the disk drives currently displayed with those originally assigned to
the Array.
In the example above, there are two disk drives attached to the WD SATA RAID Controller
and both are assigned to a RAID 1 array.
The disk drive on Channel 2 does not appear. This is the failed drive.
!
If you have a Hot Spare drive installed and enabled, the array will begin to Rebuild
automatically.
!
If you do not have a Hot Spare drive, you must replace the failed drive before a Rebuild of
the array can begin.
Refer to the WD SATA Controller User Manual for more information about replacing a failed
drive.
After you replace the failed drive, go on to “Rebuild an Array” on page 51.
