The following sections provide more information on the columns

that the disk show space command displays.

The Scsi C:ID:L Column

The Scsi C:ID:L column displays the SCSI channel number, the SCSI

device ID, and the SCSI device logical unit number for each disk on

the currently opened controller. (The display shows only one disk if

you specified a particular disk.)

In the first example, the command displays the SCSI channel

number, the SCSI device ID, and the SCSI device logical unit

number for the six disks on the open controller. In the second

example, the command displays information for the specified SCSI

device (0:02:0).

The Usage Column

The Usage column displays the type of partition or some

characteristic related to disk space usage. Specifically, the command

can display the values listed in Table 7-6.
