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). Table 1-5 SCSI Device Specifiers Example SCSI Channel Number, SCSI Device ID, SCSI Device LUN (1,1,4) Channel 1, Device 1, LUN 4 (3,2,0) (3,2) (0,1) (1) 1 Channel 3, Device 2, LUN 0 Channel 3, Device 2, LUN default1 Channel 0, Device 1, LUN default1 Channel default1, Device 1, LUN default1 Channel default1, Device 1, LUN default1 1 Set by the disk set default command. 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. 1-11
