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

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Ofine.
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.
• Device tab
Front View – Physical drives are shown Dead or Ofine and marked with a red X icon, or Missing.
Physical Drive View – Physical drives are shown Dead or Ofine and marked with a red X icon, or Missing.
• Storage tab
Disk Array and Logical Drive are marked Critical with a yellow ! icon.
