Logical Drive Status
•
OK – The normal state of a logical drive. For RAID Levels other than RAID 0
(Striping), the logical drive has full redundancy.
•
Synchronizing – When you first create a logical drive, the logical drive
synchronizes. During that time, your data is available. However, access will
be slower until synchronizing is done.
•
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). Your data is still available. However, access will
be slower until rebuilding is done.
•
Critical – This condition results from a physical drive failure. 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. See "Critical &
Offline Disk Arrays" on page 394.
•
Offline – This condition arises as the result of a second physical drive
failure. An Offline logical drive is not accessible but some or all of your data
