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:
