Disk Array and Logical Drive Problems
Disk array and logical drive problems include:
• Disk Array Degraded/Logical Drive Critical (page 400)
• Disk Array Offline/Logical Drive Offline (page 401)
• Repairing an Offline Disk Array or Logical Drive (page 402)
• Rebuilding a Disk Array (page 402)
• Incomplete Array (page 403)
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 402.
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.
WebPAM PROe reports these conditions in the following places:
• Dashboard tab
A yellow ! icon beside the disk arrays, logical drives, and physical drives
under System Status.
Major event for the logical drive under Event Information.
Warning event for the physical drive under Event Information.
