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 (below)
•
Viewing Logical Drive Information (page 128)
•
Viewing Logical Drive Statistics (page 129)
•
Making Logical Drive Settings (page 129)
•
Initializing a Logical Drive (page 129)
•
Running Redundancy Check (page 130)
•
Viewing the Logical Drive Check Table (page 131)
•
Making Logical Drive LUN Settings (page 132)
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

4.

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 302.
•
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
