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 chan‐
nel 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.
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 proper‐
ties:
mpxio-disable
Solaris I/O multipathing is enabled or disabled on fibre channel
devices with the mpxio-disable property. Specifying mpxio-dis‐
able="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 man‐
ual_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";
