Chapter 1 Workflow
This chapter describes how to set up a multipath connection using MPxIO.
Refer to "Chapter 3 Setting Up MPxIO" (page 8) for more details.
When the CPU that is installed in the server is x64, the default setting values for MPxIO are
enabled.
Confirm that the default value for MPxIO is enabled in Step 2 of the following workflow.
Workflow
Disable MPxIO on paths not requiring it (/kernel/drv/fp.conf)
Specify any devices that will not form part of the multipath connection.

Chapter 2 Using MPxIO
When using MPxIO, read the following notes carefully.
•Before installing MPxIO, also check the usage conditions and list of supported environments
given in the relevant notes in the "Notes" section of the "ETERNUS Disk storage systems
Server Connection Guide (Fibre Channel) for Oracle Solaris" and the "Server Support Matrix".
•MPxIO is bundled with Solaris 10 OS from Update 1 onwards, so separate installation is not
required for these versions.
•Download and install the Sun StorEdge SAN (MPxIO) software from the following Oracle
web-site for Solaris 10 OS, Solaris 9 OS, and Solaris 8 OS. Refer to the Oracle web-site for
more details.
http://www.oracle.com/ (Oracle web-site)
Refer to "Sun StorEdge Traffic Manager Installation and Configuration Guide" on the Oracle
web-site (http://www.oracle.com/) for more detailed information.

Chapter 3 Setting Up MPxIO
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 Solaris 10 OS
3.1.1 Disabling MPxIO on Some Paths
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 "3.1.2 Enabling MPxIO" (page
9).
Procedure
1Use 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"
2Add the following line to the "/kernel/drv/fp.conf" file using the "vi" command.
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).
# 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
name="fp" parent="Physical path" port=0 mpxio-disable="yes";

3.1.2 Enabling MPxIO
Enable MPxIO.
Enable MPxIO by adding the following line to the "/kernel/drv/fp.conf" file.
3.1.3 Checking the Storage System Status
Use the "format" command to check the path status before multipathing is set up (example
output follows).
name="fp" parent="/pci@8,600000/SUNW,qlc@2" port=0 mpxio-disable="yes";
mpxio-disable="no";
# Global mpxio-disable property:

#
# To globally disable MPxIO on all fp ports set:

3.1.4 Editing the "/kernel/drv/scsi_vhci.conf" Settings
Edit the "/kernel/drv/scsi_vhci.conf" file to enable the auto-failback function.
Check that an "auto-failback="enable";" line exists, enabling the auto-failback function.
Otherwise, add this line or change its value to "enable".
3.1.5 Reconfiguring and Restarting the Server
Reconfigure and reboot the server to effect the new settings.
The ETERNUS Disk storage system can be reconfigured by creating the "/reconfigure" file and
rebooting the server.

3.3.2 Checking the Storage System Status
Use the "format" command to check the path status before multipathing is set up (example out-
put follows).
3.3.3 Editing the "/kernel/drv/scsi_vhci.conf" Settings
Edit the "/kernel/drv/scsi_vhci.conf" file.
Procedure
1Enable MPxIO.
Check that an "mpxio-disable="no";" line exists, enabling MPxIO.
Otherwise, add this line or change its value to "no".
2Enable the auto-failback function.
Check that an "auto-failback="enable";" line exists, enabling the auto-failback function.
Otherwise, add this line or change its value to "enable".
3Enable the Symmetric option.
Add the following line.
For the ETERNUS2000
For the ETERNUS4000
For the ETERNUS8000

3.3.4 Reconfiguring and Restarting the Server
Reconfigure and restart the server to effect the new settings.
The ETERNUS Disk storage system can be reconfigured by creating the "/reconfigure" file and
rebooting the server.

3.3.5 Checking MPxIO Multipath Status
Use the "format" command to check the MPxIO multipath status after multipathing is set up
(example output follows).
Example: ETERNUS8000
Use the "luxadm" command to check that each path in the multipath configuration is normal.
Example: ETERNUS8000
Refer to the "Sun StorEdge Traffic Manager Installation and Configuration Guide" on the Oracle
web-site (http://www.oracle.com/) for details.
