Enabling MPxIO

To enable MPxIO for HP storage devices, the appropriate information for device-type-
scsioptions-list

need to be added in the /kernel/drv/scsi_vhci.conf file.

To enable MPxIO for HP:

1.

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

# vi /kernel/drv/scsi_vhci.conf

2.

Add the following lines to cover the 4x00/6x00/8x00 HP arrays:

NOTE:

You must enter six spaces after ”HP”, as shown.

device-type-scsi-options-list =

“HP HSV“, “symmetric-option“;
symmetric-option = 0x1000000;

3.

To activate the changes, run a reconfiguration reboot:

# reboot -- -r

Verifying the MPxIO configuration

To verify that MPxIO is enabled, execute the following commands:

mpathadm list lu

mpathadm show lu

IMPORTANT:

LUN 0 must not be presented to the iSCSI Initiator. Failure to do so may result in a system panic when the
mpathadm

command is invoked. See

Set configuration settings

, page 117, or the

EVA iSCSI Connectivity

Option release notes

for the procedure to remove LUN 0 from the initiator.

Verifying the number of paths

To verify the number of paths, execute the mpathadm list lu command:

# mpathadm list lu
