76 Service Port Command Reference
The SNC 4000 is addressable as a SCSI target device for command and control support. On a FC 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.

value = 0 = 0x0

To restore the capability to send commands to the command and control interface (LUN 0), use the
enableCC
command. The command is typically used to re-enable the interface after it was disabled by the
disableCC
command.
