Introduction

Table 1-5 displays valid SCSI device specifiers. The second two

examples contain a default LUN number, and the last two

examples contain default channel and LUN numbers. You can

specify these defaults using the disk set default command

(see page 5-11).

free_space

Freespace (also known as available space) is specified by a SCSI

device and, optionally, a size. If you do not specify a size,

parentheses are optional.

Therefore, the following syntaxes are allowed for the free_space

parameter:

({scsi_device},{freespace_size})

({scsi_device})

{scsi_device}

If you do not specify the freespace_size parameter, it defaults

to the size of the first freespace area available on the specified SCSI

device. Note that offsets are not specified for freespace. The offset

used is the first offset that starts a freespace area large enough to fit

size bytes.

Example SCSI Channel Number, SCSI Device ID, SCSI Device LUN

(1,1,4) Channel 1, Device 1, LUN 4

(3,2,0) Channel 3, Device 2, LUN 0

(3,2) Channel 3, Device 2, LUN default

Set by the disk set default command.
