Chapter 4: Management with WebPAM PRO
91
When a disk drive fails, it disappears from the WebPAM interface. You can
identify the failed drive under Disk View, noting that there is no drive showing for
Channel 3. The failed drive displays a red Status LED.
The Promise RAID controller will automatically attempt to activate a hot spare
drive and rebuild it to become part of the logical drive (above). The drive in
Channel 4 is the hot spare drive in this example.
If the hot spare feature is deactivated or no hot spare drive is available, the
controller will attempt to rebuild the failed drive.
During rebuild, the alarm sounds a single short beep, repeated. The disk drive
being rebuilt displays an amber Status LED.
During rebuilding, you can still read and write data to the logical drive. However,
fault tolerance is lost until the logical drive is restored to Functional status.
Important
If the same disk drive repeatedly fails and makes the logical drive
go critical, replace the disk drive with one of the same capacity.
