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 109
(WebPAM PROe) or page 148 (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.
