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