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veries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.
