• 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.
• Offline – This condition arises as the result of a second physical drive failure.
An Offline logical drive is not accessible but some or all of your data may
remain intact. You must determine the cause of the problem and correct it.
• 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.
To create a logical drive, see “Creating a Logical Drive” on page 111.
To delete a logical drive, see “Deleting a Logical Drive” on page 113.
For a Degraded or Offline logical drive, see “Critical & Offline Disk Arrays” on
