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 interfaces.

       The fp driver requires the presence of a fabric name server in fabric and public loop topologies to discover fibre channel devices. In pri-
       vate  loop  topologies,	the  driver discovers devices by performing PLOGI to all valid AL_PAs, provided that devices do not participate in
       LIRP and LILP stages of loop initialization. The fp driver also discovers devices in N_Port 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. Specifying 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 setting for the specified ports. The following example shows how to disable mul-
	   tipathing 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";

       manual_configuration_only

	   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 manual_configuration_only property may be configured  to disable the
	   default behavior and force the manual configuration of the devices in the  SAN.  Specifying	manual_configuration_only=1  disables  the
	   automatic configuration of devices.

       pwwn-lun-blacklist

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

		  #
		  # pwwn-lun-blacklist=
		  # "target-port-wwn,lun-list"
		  #
		  # To prevent LUNs 1 and 2 from being configured for target
		  # port 510000f010fd92a1 and target port 510000e012079df1, set:
		  #
		  # pwwn-lun-blacklist=
		  # "510000f010fd92a1,1,2",
		  # "510000e012079df1,1,2";
		  #

NOTES
       In N_Port 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.
