Disabling MPxIO on Some Paths
When multipathing is not required for some devices, the procedure that follows should be used to
add the physical paths of these devices to the "/kernel/drv/fp.conf" file, in order to disable use of
the multipath function for these devices.
This is not necessary when multipathing is to be set up for all devices recognized by the OS, in
which case proceed to

If this setting is omitted, multipathing is set up for all LUNs recognized by
the OS.
MPxIO must be disabled for the paths of connected devices that MPxIO
does not support (such as a tape device).
Use the "cat" command (etc.) to check the "/etc/path_to_inst" file and identify the
physical pathname of the device for which multipathing is not required.
In this example, the physical path is "/pci@8,600000/SUNW,qlc@2"
# cat /etc/path_to_inst
"/pci@8,600000/SUNW,qlc@2" 0 "qlc"
"/pci@8,600000/SUNW,qlc@2/fp@0,0" 5 "fp"
"/pci@8,600000/SUNW,qlc@2/fp@0,0/ssd@w500000e0113ce2e1,0" 5 "ssd"
Physical path
Add the following line to the "/kernel/drv/fp.conf" file using the "vi" command.
name="fp" parent="Physical path" port=0 mpxio-disable="yes";
Example:
name="fp" parent="/pci@8,600000/SUNW,qlc@2" port=0 mpxio-disable="yes";
