What is the Command Console LUN?
StorageWorks Command Console (SWCC) software communicates with the
HSG80 controllers through an existing storage unit, or logical unit number
(LUN). The dedicated LUN that SWCC uses is called the Command Console
LUN (CCL). The CCL serves as the communication device for the HS-Series
Agent and identifies itself to the host by a unique identification string. By default,
a CCL device is enabled within the HSG80 controller on host port 1. The HSG80
both SCSI-2 or SCSI-3 uses with your platform.
The CCL does the following:
■ Allows the RAID Array to be recognized by the host as soon as it is attached
to the SCSI bus and configured into the operating system.
■ Serves as a communications device for the HS-Series Agent. The CCL
identifies itself to the host by a unique identification string.
In dual-redundant controller configurations, the commands described in the
following sections alter the setting of the CCL on both controllers. The CCL is
enabled only on host port 1. At least one storage device of any type must be
configured on host port 2 before installing the Agent on a host connected to host
port 2.
Select a storageset that you plan to configure and that is not likely to change. This
storageset can be used by the Agent to communicate with the RAID Array.
Deleting this storageset (LUN) later breaks the connection between the Agent and
the RAID Array.
Determining the Address of the CCL
CCL is enabled by default. Its address can be determined by using the following
CLI command:
HSG80 > SHOW THIS_CONTROLLER
Enabling/Disabling the CCL in SCSI-2 Mode
Enabling the CCL
To enable the CCL in SCSI-2 mode, use the following CLI command:
HSG80 > SET THIS_CONTROLLER COMMAND_CONSOLE_LUN
