.. versionchanged:: %s
It is sufficient to specify an FCP device bus ID if automatic LUN scanning
is available. Otherwise all three parameters are required.
``zfcp --devnum=<devnum> [--wwpn=<wwpn> --fcplun=<lun>]``
Automatic LUN scanning is available for FCP devices operating in NPIV mode
if it is not disabled through the `zfcp.allow_lun_scan` module parameter
(enabled by default). It provides access to all SCSI devices, that is, WWPNs
and FCP LUNs, found in the storage area network attached to the FCP device
with the specified bus ID.
