Disk arrays are made up of physical drives. Logical drives are created on the disk array. When a disk array and
its logical drives go Offline, the data stored in the logical drives is no longer accessible.
RAID 0 logical drives go Offline when ONE physical drive is removed or fails.
RAID 1, 1E, 3, 5, 10, 30, and 50 logical drives go Offline when TWO physical drives are removed or fail.
RAID 6 and 60 logical drives go Offline when THREE physical drives are removed or fail.

If a logical drive based on a non-fault-tolerant disk array, RAID 0, goes offline, all of the data on the logical
drive is lost.
To recreate your logical drive:
1. Identify the failed physical drive.
See "Locating a Physical Drive".
2. Replace the failed drive.
3. See "Installing Physical Drives" on page 16.
4. If the disk array had more than one physical drive, delete the disk array and re-create it.
See "Deleting a Disk Array" and "Creating a Disk Array Manually".
5. Restore the data from your backup source.
