Managing Logical Drives
The Logical Drive Management function deals with settings and functions of
existing logical drives. To create or delete a logical drive, see “Managing Disk
Arrays” on page 147. Logical drive management includes:
• Viewing Logical Drive Information (page 158)
• Setting an Alias for a Logical Drive (page 159)
• Setting Write Cache Policy (page 159)
• Setting Read Cache Policy (page 159)
• Initializing a Logical Drive (page 160)
• Running Redundancy Check (page 160)
• Locating a Logical Drive (page 161)
Viewing Logical Drive Information
To view logical drive information:
1. From the Main Menu, highlight Logical Drive Management and press Enter.
2. Highlight the logical drive you want and press Enter.
The information and settings screen appears.
3. Highlight any of the following and press Enter to view more information:
• Check Table – Read Check, Write Check, and Inconsistent Block Tables
• Logical Drive Statistics
Logical Drive 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
(Striping), 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 a logical drive is Synchronizing, it will function and your data is
available. However, access will be slower due to the synchronizing
operation.
• 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.
• Critical – 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.
