About the Command Console LUN (CCL)
The CCL is a preconfigured virtual LUN, located on controller A, LUN 0. Logical
unit numbers (LUNs) are unique identifiers used on a SCSI bus to distinguish
between devices that share the same bus. The host uses LUNs to access the
storageset.
SWCC sees the CCL as a virtual disk; however, the CCL cannot store
information. The CCL is used only as a communication path between the
controller and SWCC.
If you enable the CCL, the controller reserves one LUN address for Client or
Agent use. The reserved LUN address is stored under the Communications LUN
tab. The CCL does the following:
■ Allows the host to recognize the RAID Array as soon as it is attached to the
SCSI bus and configured on 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. This string,
HSG60CCL or HSG80CCL, is returned in response to the inquiry command.
The default state for the CCL is enabled. To determine the address of the CCL,
enter the following CLI command:
HSG60 > SHOW THIS_CONTROLLER
OR
HSG80 > SHOW THIS_CONTROLLER
