Add Unit - Compaq StorageWorks HSZ80 Configuration And Cli Reference Manual

ADD UNIT

Creates a logical unit from a device, container, or partition. The controller maps all
requests from the host to the logical-unit number as requests to the container specified
in the ADD UNIT command.
If you add a newly created storageset or disk to your subsystem, you must initialize it
before it can be added as a logical unit. If you are adding a storageset or disk that has
data on it that you want to maintain, do not initialize it; it will be added as a logical
unit.
Syntax
ADD UNIT unit-number container-name
Parameters
unit-number
Assigns a number to the unit being created from a device, container, or partition in the
subsystem. The host uses this number to indicate the source or target for every I/O
request it sends to the controller. The unit-number is a host-addressable LUN. The
unit-number is assigned to one of the host ports.
Containers must have units that are on a single port. Do not split partitioned units
across ports.
container-name
Specifies the name of the container (disk drive, device, storageset, or partition) being
used to create the unit.
A maximum of 48 devices can make up one unit.
