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.
If you enter the disableCC command without specifying an option
CAUTION
number, it has the same effect as disableCC 1.
SNC4000 > disableCC
value = 0 = 0x0

enableCC
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.

envMonShow
The envMonShow command lists all of the environmental channel states and their current values. Use the
command envMonRangeShow to restrict output to a display of the ranges relevant to each state. The
following channels have been defined:
