Disk array and logical drive problems include:
• “Disk Array Degraded / Logical Drive Critical” (below)
• “Disk Array Offline / Logical Drive Offline” on page 633
• “Repairing an Offline Disk Array or Logical Drive” on page 634
• “Rebuilding a Disk Array” on page 635
• “Incomplete Array” on page 635
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 635.

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.
