The SNC 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.
