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.
