3.3.1 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
"3.3.2 Checking the Storage System Status" (page 17) .
Procedure
1
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"
2
Add the following line to the "/kernel/drv/fp.conf" file using the "vi" command.
Example:
End of procedure
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).
