The MPxIO set up procedure is common to all ETERNUS2000, ETERNUS4000, and

ETERNUS8000 Disk storage systems, but some settings vary depending on the Solaris OS ver-

sion.

Set up MPxIO according to the Solaris OS version being used.

3.1

3.1.1

When multipathing is not required for the specific LUN, use the following procedure to add phys-

ical paths for the relevant device to the "/kernel/drv/fp.conf" file in order to disable the multipath

function for the device.

Disabling the multipath function is not necessary when multipathing is to be set up for all the

LUNs that are recognized by the OS. In these cases, proceed to

9).

Setting Up MPxIO

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).

Procedure

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";
