Disk Array 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.

• Forced Offline – This drive was forced offline by the user.

• Forced Online – This drive was forced online by the user.

• Transition Running – A Transition is running that involves this physical drive.

• PDM Running – PDM is running on this physical drive.

• Media Patrol Running – Media Patrol is running on this physical drive.

• Stale – The physical drive contains obsolete disk array information. Click on

the Clear tab.

• PFA – The physical drive has errors resulting in a prediction of failure. Click

on the Clear tab.

• 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.

• Dead – The physical drive has failed.
