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 VTrak controller detects the new drive in slot 3, the controller:
• Automatically transitions the data on drive 6 to drive 3
• Returns 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 “Running
a Transition on a Spare Drive” on page 144 or “Running Transition on a Disk
Array” on page 190.
