OK

– This is the normal state of a logical drive. When a logical drive is Functional, it is ready for immediate

use. For RAID Levels other than RAID 0 (Striping), the logical drive has full redundancy.

Synchronizing

– This condition is temporary. Synchronizing is a maintenance function that verifies the

integrity of data and redundancy in the logical drive. When a logical drive is Synchronizing, it functions and

your data is available. However, access is slower due to the synchronizing operation.

Critical/Degraded

– This condition arises as the result of a physical drive failure. A degraded logical

drive still functions and your data is still available. However, the logical drive has lost redundancy (fault

tolerance). You must determine the cause of the problem and correct it.

Rebuilding

– This condition is temporary. When a physical drive has been replaced, the logical drive

automatically begins rebuilding in order to restore redundancy (fault tolerance). When a logical drive is

rebuilding, it functions and your data is available. However, access is slower due to the rebuilding operation.

Transport Ready

– After you perform a successful Prepare for Transport operation, this condition

means you can remove the physical drives of this disk array and move them to another enclosure or

different drive slots. After you relocate the physical drives, the disk array status shows OK.
