disableCC [option number]

Disable the command and control interface (LUN 0) using the disableCC command. Specify one of two option parameters as follows.

	Option	Value
	Number	Value
	Number

1Hides the Command and Control interface and results in Inquiry data returning “device not available” for LUN 0.

2Completely disables all Command and Control functions

The SNC 5100 is addressable as a SCSI target device for command and control support. On a Fibre Channel Interface, this device will be seen as logical unit number 0, (LUN 0). The LUN 0 device returns a device type of 0Ch in an inquiry command, indicating it is a controller device. Controller devices are defined in the SCSI-3 Controller Commands specification (SCC).

In some cases, it may be desirable to disable this feature. If LUN 0 is disabled, then a device type of 2Ch will be returned in an inquiry to LUN 0, indicating that the device is not presently available at this LUN. LUN 0 will remain reserved for the Command and Control interface and will not be allocated to another target device.

Other commands are available for re-enabling the Command and Control interface or reassigning it to a different LUN rather than hiding or disabling it. See the enableCC command and the setSnaCCLun command for further information.

Caution

If you enter the disableCC command without specifying an option number, it has the same effect as disableCC 1
