 RAID level migration  Disk array transport Disk Array Degraded 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, a RAID 1, 5 and 10 volume will (or in the case of a RAID 6, two drives must fail):  The operational status of the disk array becomes Degraded.  The operational status of logical drives becomes Critical.  The operational status of physical drive becomes Dead or Offline. Disk Array Offline When a disk array and its logical drives go Offline, the data stored in the logical drives is no longer accessible.  Logical drives based on fault-tolerant disk arrays, RAID 1, 5, and 10, go Offline when two physical drives are removed or fail.  RAID 6 can continue to operate when two physical drives are removed or fail. It will fail when three physical drives are removed or fail.  Logical drives based on non-fault tolerant disk arrays, RAID 0, go Offline when a one physical drive is removed or fails. 3.7.4 Disk Array Management To view disk array information: 1. Click the Storage tab. 2. Click the Disk Array button. 3. Mouse-over the disk array you want to see and click the View button. Disk array information includes:  Disk Array ID - DA0, DA1, DA2, etc. 37
