WD ARRAY MANAGEMENT SETUP
CHAPTER 5: RAID MONITORING AND MAINTENANCE WITH AMS - 50
USER MANUAL
Array Offline
When a disk drive fails on a non-fault-tolerant array (RAID 0) for any reason, the Array goes
Offline. The array cannot read or write data. All of the data on the array will be lost unless the
failed drive is restored to operation.
A fault-tolerant array (RAID 1) will go Offline if two disk drives fail.
An Array Offline 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 Disk View icon to expand it.
2. Click on the Array View icon to expand it.
3. Look for the drive that was part of this Array but is now missing. Observe and compare
the disk drives under the Controller with those under the Array.
In the example above, two disk drives attached to the WD SATA RAID Controller were
assigned to a RAID 0 array.
The disk drive on Channel 1 is present, but the second drive is not. The second is the
failed drive.
4. When you have identified the failed drive, check its connections and run the drive
manufacturer's diagnostic program in an effort to restore the drive to operation.
There is no Rebuild function for a non-fault-tolerant array.
