Reconfiguring and Restarting the Server

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

# Use is subject to license terms.

#pragma ident "@(#)scsi_vhci.conf 1.9 04/08/26 SMI"

name="scsi_vhci" class="root";

# Load balancing global configuration: setting load-balance="none" will cause

# all I/O to a given device (which supports multipath I/O) to occur via one

# path. Setting load-balance="round-robin" will cause each path to the device

# to be used in turn.

load-balance="round-robin";

# Automatic failback configuration

# possible values are auto-failback="enable" or auto-failback="disable"

auto-failback="enable";

# For enabling MPxIO support for 3rd party symmetric device need an

# entry similar to following in this file. Just replace the "SUN SENA"

# part with the Vendor ID/Product ID for the device, exactly as reported by

# Inquiry cmd.

# device-type-scsi-options-list =

# "SUN SENA", "symmetric-option";

# symmetric-option = 0x1000000;

Check that "round-robin" is set for (1).

Check that "enable" is set for (2).

Reconfiguring and Restarting the Server

Reconfigure and restart the server to effect the new settings.

# touch /reconfigure

# /usr/sbin/shutdown -y -g0 -i6

Use the "format" command to check the MPxIO multipath status after multipathing is set up.

Example: ETERNUS DX80
