Managing Logical Drives

Logical drives are made from disk arrays. In the Tree, you can see a graphic representation of the logical drives that belong to each array. You can see a summary of all logical drives in the subsystem under Logical Drive Summary.

Logical drive management includes the following functions:

•Viewing Information for All Logical Drives (page 166)

•Locating a Logical Drive (page 167)

•Viewing Logical Drive Information (page 167)

•Viewing Logical Drive Statistics (page 168)

•Changing Logical Drive Settings (page 168)

•Initializing a Logical Drive (page 169)

•Running Redundancy Check (page 170)

•Viewing the Logical Drive Check Table (page 170)

Viewing Information for All Logical Drives

To view information about all logical drives in a disk array:

1.Click the Subsystem icon in Tree View.

2.Click the Disk Arrays icon.

3.Click the Disk Array icon.

4.Click the Logical Drives icon

Logical Drive Status

•OK – This is the normal state of a logical drive. When a logical drive is OK, it is ready for immediate use. For RAID Levels other than RAID 0 (Striping), the logical drive has fault tolerance.

•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. Or, one of the physical drives was accidently or intentionally disconnected or pulled from its enclosure. A critical or degraded logical drive will still function and your data is still available. However, the logical drive has lost its fault tolerance.

•Rebuilding – This condition is temporary. When a physical drive has been replaced, the logical drive automatically begins rebuilding in order to restore
