To activate an offline RAID 1 logical drive:

1. Click on the Logical Drive View icon in Tree View.

2. Click on the Logical Drive icon of the offline logical drive.

3. Click on the Activation tab in Management View.

4. Click the Activation button.

The logical drive converts to Critical status. You can now rebuild the logical

drive. See “Logical Drive Rebuild” on page 77.

Logical Drive Critical / Offline

A RAID 1 logical drive goes critical when a physical (disk) drive is removed or

fails. Due to the fault tolerance of the logical drive, the data is still available and

online. However, once the logical drive goes critical, it has lost its fault tolerance

and performance may be adversely affected.

If the fault was caused by a failed physical drive, the drive must be replaced by

another drive, either identical or larger, in order for the RAID system to rebuild

and restore optimal configuration.

A non-fault tolerant logical drive—RAID 0—goes offline when a physical drive is

removed or fails. Since the logical drive is not fault tolerant, the data stored in the

disk array is no longer accessible.

If one physical drive fails, all of the data on the logical drive is lost. You must

replace the failed drive. Then, if the logical drive had more than one disk drive,

delete the logical drive and re-create it. Restore the data from a backup source.
