Chapter 9

Setting the Multipaths

For the iSCSI LAN (used to transfer data), do not set multipath configuration with IP Network Multipathing

(IPMP).

When configuring the multipath, use MPxIO in the same way as FC-SAN is used for configuration.

9.1

Enabling MPxIO

Enable MPxIO.

Check the [mpxio-disable="no"] line in the "/kernel/drv/iscsi.conf" file.

Change the parameter to "no" when "yes" is set.

Example for changing the "/kernel/drv/iscsi.conf" file:

# 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";

Check whether "no" is set for the underlined portion.

9.2

Editing "/kernel/drv/scsi_vhci.conf"

Edit the "/kernel/drv/scsi_vhci.conf" file.

Specify the multipath control method.

Check that a "load-balance="round-robin";" line exists.

Otherwise, add this line or change its value to "enable".

Enable the auto-failback function.

Check that an "auto-failback="enable";" line exists.
