•
Operational Status – The operating condition of a logical drive.
•
OK / Functional – This is the normal state of a logical drive. When a
logical drive is OK / 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 an 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
Critical 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.
•
Offline – This condition arises as the result of a second physical drive
failure. An Offline logical drive is not accessable but some or all of your
data may remain intact. You must determine the cause of the problem
and correct it.
•
Capacity – The data storage capacity of this logical drive.
•
Number of Used Physical Drives – The number of physical drives used by
this logical drive.
•
Stripe Size – The stipe block size of this logical drive specified at its
creation.
•
Disk Array ID – The disk array ID number to which this logical drive belongs.
•
SCSI Channel 1 TIDs – The Target IDs assigned to SCSI channel 1.
•
SCSI Channel 2 TIDs – The Target IDs assigned to SCSI channel 2.
