HP Array Controller HSG V8.7 Software - Manual (Page 281)

CLI Commands B–9
In transparent failover mode and normal mode, host connections on
controller port 1 have an offset of 0 and host connections on controller
port 2 have an offset of 100. These are the default offset values.
The relationship between LUN number, unit number, and offset is as
follows:
n LUN number = unit number - offset.
n Logical unit number or LUN number = the logical unit number
presented to the host connection.
n Unit number = the number assigned to the unit in the ADD UNIT
command. This is the number by which the unit is known
internally to the controllers.
Note If the SET controller SCSI_VERSION=SCSI-3, the command
console LUN (CCL) is presented as LUN 0 to every connection,
superceding any unit assignments. See “ADD UNIT,” page B–27, for
more information.
OPERATING_SYSTEM=OS_name
Specifies the operating system of the host. The choices are:
n DIGITAL_UNIX
n IBM
n SNI
n SUN
n VMS
n WINNT
Examples
This will add to the table of known connections, an entry for a
connection named George with the indicated host and adapter
worldwide names, on port 2 of “this controller.”
