Managing Logical Drives; Viewing Information For All Logical Drives - Promise Technology VTRAK E310f Product Manual

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 127)
• Viewing Logical Drive Information (page 128)
• Viewing Logical Drive Statistics (page 129)
• Making Logical Drive Settings (page 129)
• Initializing a Logical Drive (page 130)
• 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
2. Click the Disk Arrays
3. Click the Disk Array
4. Click the Logical Drives
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.
