MPxIO overview

The Oracle multipathing software (MPxIO) provides basic failover and load-balancing capability

to HP P6000, and EVA4x00/6x00/8x00 storage systems. MPxIO allows the merging of multiple

SCSI layer paths, such as an iSCSI device exposing the same LUN via several different iSCSI target

names. Because MPxIO is independent of transport, it can multipath a target that is visible on both

iSCSI and FC ports. This section describes only the iSCSI implementation of MPxIO with the iSCSI

or iSCSI/FCoE modules.

For more information about MPxIO, see the

Solaris Fibre Channel and Storage Multipathing

Administration Guide

Preparing the host system

To verify that MPxIO is enabled:

Enter the following command to verify that the MPIO setting is

cat kernel/drv/iscsi.conf

2. Verify

mpxio-disable=

”

If setting is

yes

change to

, and reboot:

Reboot -- -r

Example:

MPxIO on all iSCSI port settings in

/kernel/dev/iscsi.conf

# Use is subject to license terms.

#ident "@(#)iscsi.conf 1.2 06/06/12 SMI"

name="iscsi" parent="/" instance=0;

ddi-forceattach=1;

# I/O multipathing feature (MPxIO) can be enabled or disabled using

# mpxio-disable property. Setting mpxio-disable="no" will activate

# I/O multipathing; setting mpxio-disable="yes" disables the feature.

# Global mpxio-disable property:

# To globally enable MPxIO on all iscsi ports set:

# mpxio-disable="no";#

# To globally disable MPxIO on all iscsi ports set:

# mpxio-disable="yes";

mpxio-disable="no";

Enabling MPxIO for HP P6300/P6500 EVA

This section describes the steps necessary to configure a Solaris server to recognize an HP storage

array in an iSCSI multipath environment with the iSCSI or iSCSI/FCoE modules.

Edit the

scsi_vhci.conf

file

HP EVA storage arrays are supported with MPxIO:

•

As symmetric devices only

•

With no load balancing

•

With no failback

To configure MPxIO for HP storage devices, the appropriate information needs to be added in the

/kernel/drv/scsi_vhci.conf

file. To enable MPxIO for HP storage:

Use a text editor to change the configuration file. For example:

# vi /kernel/drv/scsi_vhci.conf
