Logical drives derive from disk arrays. In the tree view, you can see the icons for the logical

drives that belong to each array. You can access the logical drive list in the tree view by

expanding the disk array, and clicking the logical drive icon for any existing disk array, or

simply clicking the subsystem's Logical Drive Summary icon.

Click on any logical drive (LD) in the list to view information and statistics, to change settings

(Alias, Read Policy, Write Policy), to start background activities (Initialization, Redundancy

Check), or to view the LD checklist.

Bosch Security Systems B.V.

OK - This is the normal state of the logical drive. When the logical drive is operating

properly, 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 the logical drive is

synchronizing, it keeps operating and the data is available. However, access is slower due

to the synchronizing operation.

Critical / Degraded - This condition occurs due to the failure of the physical drive. The

degraded logical drive keeps operating and the data is still available. However, the logical

drive has lost redundancy (fault tolerance). You shall identify the cause of the problem

and correct it.

Rebuilding - This condition is temporary. When the physical drive has been replaced, the

logical drive automatically starts rebuilding in order to restore redundancy (fault

tolerance). When the logical drive is rebuilding, it keeps operating and the data is

available. However, access is slower due to the rebuilding operation.
