Compaq HSZ80 manual Configuring with the Command Console LUN, Enabling and Disabling the CCL

4–19

Configuring with the Command Console LUN

The Command Console LUN (CCL) acts as a type of access device in the form of a LUN for communicating between the host and the controller. You can access the CCL using either StorageWorks Command Console (SWCC) or CLI commands. When the CCL is enabled, you can communicate between the controller and the host without a maintenance port cable.

The most common tasks performed with the CCL include configuring storage units, preparing the subsystem for use, checking a failed set, checking performance by running VTDPY, and running FMU for troubleshooting. You should not use the CCL for maintenance using the following utilities and exercisers: HSUTIL, FRUTIL, and DILX. For these tasks, you would need to communicate with the controller through the maintenance port cable.

Enabling and Disabling the CCL

IMPORTANT: You cannot disable the CCL in SCSI-3 mode. It is always enabled.

If the CCL is not enabled automatically on your controller, use the following command:

SET THIS_CONTROLLER COMMAND_CONSOLE_LUN

To turn it off, use the following command:

CAUTION: Disabling the CCL while SWCC is running may result in loss of connection for the StorageWorks Command Console. Turn off SWCC before issuing the command.

SET THIS_CONTROLLER NOCOMMAND_CONSOLE_LUN
