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.
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:
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";
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.
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"; #

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.
