The list of disk arrays appears.
3. Click the disk array you want, then click the View button.
Array information displays, including:
• ID – DA0, DA1, DA2, etc.
• Alias – If assigned
• Operational Status – OK is normal
• Media Patrol – Enabled or disabled on this array
• PDM – Enabled or disabled on this array
• Total Capacity – Data capacity of the array
• Configurable Capacity – Maximum usable capacity of the array
• Free Capacity –Unconfigured or unused capacity on the physical drives
• Number of Physical Drives – The number of physical drives in this
array
• Number of Logical Drives – The number of logical drives on this array
• Max Contiguous Free Capacity – Unconfigured or unused capacity in
contiguous sectors on the physical drives
• Available RAID Levels – RAID levels you can specify on this array
Disk Array Operational 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 functions and your
data is available. However, access is slower due to the synchronizing
operation.
• Critical/Degraded – This condition arises as the result of a physical drive
failure. A degraded logical drive still functions 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 functions
and your data is available. However, access is 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 shows OK.
