View Drive Assignments

From the Main Menu screen, press 1 to see the View Drive Assignments screen (below).

This screen reports disk drive assigments and provides the following information:

Channel: ID – Shows the FastTrak Controller channel ID (SX4300, 1 through 4; SX8300, 1 through 8) to which a particular disk drive is attached.

Drive Model – Identifies the manufacturer, model, and model number (if applicable) of each disk drive.

Capacity (MB) – Reflects the capacity in MB (megabytes) of the disk drive.

Assignment – This field identifies the logical drive to which the disk drive belongs. In the example above, there is one logical drive composed of three disk drives. LD 1-2 means logical drive 1, disk drive 2.

Unassigned drives are labeled free and are considered hot spares to provide fault tolerance. Unassigned drives may also be used to create a new logical drive at any time.

Extent – An extent is a portion of the disk drive. The FastTrak SX Series controller allows you to split the capacity of a disk drives between two logical drives. The portion of a disk drive available to be used in a logical drive is called an extent. The extent, or sum of two extents, is slightly smaller than the total capacity of the disk drive.

See “View Drive Assignments, Split Disk Drives” on page 20 for an example of two extents for each disk drive.
