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 private 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 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";

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
spaces 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";
