Configuring G-SPEED Studio R
Media Type
(type of physical drive)
• Hard disk drive (HDD)
Requirements
The spare drive must have adequate capacity to replace the largest physical drive in
your disk arrays. Additionally, it must be the same media type as the physical drives in
your disk arrays. A revertible spare drive requires you to replace the failed physical drive
in the disk array and run the Transition function.
Transition
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, whereupon
the revertible spare drive will return to its original status. To run the Transition function,
the spare drive must be revertible.
In addition, you must specify an unconfigured physical drive of the same or larger
capacity and the same media type as the revertible spare drive.
Running a Transition
The Transition feature enables you to specify “permanent” spare drives for your
G-SPEED Studio R unit. 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 will return to its original status.
Transition happens automatically when the following sequence of events takes place:
• You create a revertible spare drive. See
Creating a Spare Drive Manually
.
• A physical drive assigned to your disk array fails and the array goes Critical or
Degraded.
