VTrak M-Class Product Manual
•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.
•Stripe – The stripe size of the logical drive.
•Sector
•Status
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.
•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.
