There is no spare drive at this moment. Even if physical drive 5 is of adequate

capacity, it has not been designated as a spare, therefore the controller cannot

use it as a spare.

Automatic Transition

At this juncture, you would replace the failed drive in slot 3 with a new one of the

same or greater capacity.

When the VessRAID controller detects the new drive in slot 3, it will:

• Automatically transition the data on drive 6 to drive 3

• Return drive 6 to spare status

When the Automatic Transition is finished, physical drives 1, 2, 3, and 4 belong to

the disk array and physical drive 6 is a revertible spare drive. The original

configuration is restored.

Manual Transition

If you wanted to use the drive in slot 5 as a member of the disk array, rather than

the drive in slot 3, you would run the Transition function manually. See page 116

(WebPAM PROe) or page 156 (CLU).

When the Manual Transition is finished, physical drives 1, 2, 4, and 5 belong to

the disk array and physical drive 6 is a revertible spare drive.

At this point, you would replace the drive in slot 3. The new drive in slot 3 will be

unconfigured until you assign it to a disk array or as a spare.
