Transition
The Transition feature enables you to specify "permanent" spare drives for your
VessRAID subsystem. Transition is the process of replacing a revertible spare
drive that is currently part of a disk array with an unconfigured physical drive or a
non-revertible spare. The revertible spare drive returns to its original status.
Transition happens automatically when the following sequence of events takes
place:
•
You create a revertible spare drive.
See page 176 (WebPAM PROe) or page 241 (CLU).
•
A physical drive assigned to your disk array fails and the array goes critical
or degraded.
•
VessRAID automatically rebuilds your array to the revertible spare drive and
the array becomes functional again.
•
You replace the failed physical drive with a new physical drive of equal or
greater capacity.
•
VessRAID automatically transitions (moves) the data from the revertible
spare to the new physical drive.
•
The new physical drive becomes part of the array and the revertible spare
drive returns to its original spare status.
Transition happens manually when you specify a different unconfigured physical
drive to transition (move) the data from the revertible spare drive.
See the example below.
VessRAID supports disk drive hot-swapping. To avoid hand
contact with an electrical hazard, do not remove more than one
drive carrier a time.
