RAID Level – The RAID level of this logical drive (It may differ from the disk
array).

•
Capacity – This is the data storage capacity available.
•
Disk Array ID – The ID number of the disk array from which this logical drive
was created.
was created.
•
Stripe – The stripe size of the logical drive.
•
Sector –The sector size of the logical drive.
•
Status –The operational status of the logical drive (see below).
Logical Drive Status
•
Functional/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.

•
Critical/Degraded – 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.

•
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.

Transport Ready – After you perform a successful Prepare for Transport
operation, this condition means you can remove the physical drives of this
disk array and move them to another enclosure or different drive slots. After
you relocate the physical drives, the disk array status will show OK.
