Disk Array Operational Status
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, 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 will function and your data
is available. However, access will be slower due to the synchronizing operation.
Critical / Degraded – This condition arises as the result of a physical drive failure. A degraded logical drive
will still function 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 will function and your data is available. However, access will be slower due to the rebuilding operation.
