Configuration Guide
host port 1. The HSG80 uses both SCSI-2 and SCSI-3. CCL behaves differently for each
and Windows NT and Windows 2000 have specific requirements for CCL behavior. See
Chapter 3 for a more detailed explanation.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 entering the following CLI
command:
HSG80 > SHOW THIS_CONTROLLER
Enabling/Disabling the CCL in SCSI-2 Mode
Enabling the CCL
To enable the CCL, enter the following CLI command:
HSG80 > SET THIS_CONTROLLER COMMAND_CONSOLE_LUN
Disabling the CCL
To disable the CCL, enter the following CLI command:
HSG80 > SET THIS_CONTROLLER NOCOMMAND_CONSOLE_LUN
To see the state of the CCL, use the SHOW THIS CONTROLLER/ OTHER CONTROLLER command.
Because the CCL is not an actual LUN, the SHOW UNITS command will not display the CCL
location.
