• 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.

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.
