NAME
     fp - Sun Fibre Channel port driver

DESCRIPTION
     The fp driver is a  Sun  fibre  channel  nexus  driver  that
     enables  fibre channel topology discovery, device discovery,
     fibre channel adapter port management and other capabilities
     through  well-defined  fibre  channel  adapter driver inter-
     faces.


     The fp driver requires the presence of a fabric name  server
     in fabric and public loop topologies to discover fibre chan-
     nel devices. In private loop topologies, the driver  discov-
     ers  devices  by  performing PLOGI to all valid ALPAs, pro-
     vided that devices do  not  participate  in  LIRP  and  LILP
     stages  of loop initialization. The fp driver also discovers
     devices in NPort point-to-point topologies.

CONFIGURATION
     The fp driver is configured by defining  properties  in  the
     fp.conf  file.  Note that you must reboot the system to have
     any changes you make to fp.conf take effect. The  fp  driver
     supports the following properties:

     mpxio-disable

         Solaris I/O multipathing is enabled or disabled on fibre
         channel  devices with the mpxio-disable property. Speci-
         fying  mpxio-disable="no"  activates  I/O  multipathing,
         while  mpxio-disable="yes" disables the feature. Solaris
         I/O multipathing may be enabled or  disabled  on  a  per
         port  basis.  Per port settings override the global set-
         ting for the  specified  ports.  The  following  example
         shows how to disable multipathing on port 0 whose parent
         is /pci@8,600000/SUNW,qlc@4:

           name="fp"    parent="/pci@8,600000/SUNW,qlc@4"    port=0
           mpxio-disable="yes";



     manualconfigurationonly

         Automatic configuration of SCSI devices in the fabric is
         enabled   by   default   and  thus  allows  all  devices
         discovered in the SAN zone to   be  enumerated   in  the
         kernel's      device     tree     automatically.     The
         manualconfigurationonly property may be configured  to
         disable the default behavior and force the manual confi-
         guration  of  the  devices  in   the   SAN.   Specifying
         manualconfigurationonly=1   disables   the   automatic

         configuration of devices.


     pwwn-lun-blacklist

         Allows you to specify target port WNs and  LUN  numbers
         you  do not want configured. LUN numbers are interpreted
         as decimals. White spaces and commas (',') can  be  used
         in the list of LUN numbers.

                #
                # To prevent LUNs 1 and 2 from being configured for target
                # port 510000f010fd92a1 and target port 510000e012079df1, set:

NOTES
     In NPort point-to-point topologies, FCP error recovery does
     not  work  across events such as link bounce/cable pull. I/O
     to devices with FCP-2/FCP-3 support (for  example,  FC  tape
     drives) will be disrupted by such events.
