Disk array problems typically result from a physical drive failure. The most
common problem is a degraded disk array. The RAID controller can rebuild a
degraded disk array. See "Rebuilding a Disk Array" on page 112.
Disk Array Degraded/Logical Drive Critical
Disk arrays are made up of physical drives. Logical drives are created on the disk
array.
When one of the physical drives in a disk array fails:
•
The operational status of the disk array becomes Critical.
•
The operational status of the logical drives becomes Critical or Degraded.
•
The operational status of the physical drive becomes Dead or Offline.
The Promise Utility reports these conditions in the following places:
•
Dashboard icon – A yellow !
and physical drives under System Status.
•
Physical Drive icon – Physical drives are shown Dead or Offline and marked
with a red X
•
Logical Drive icon – Disk Array and Logical Drive are marked Critical with a
yellow !
RAID 6 logical drives are marked:
•
Degraded with a yellow !
•
