Enabling MPxIO for an HP EVA storage array
This section explains how to configure a Solaris server to recognize an HP storage array in an iSCSI
multipath environment with the MPX200.
Editing the scsi_vhci.conf file
HP storage arrays are supported with MPxIO:
• As symmetric devices only
• With no load balancing
• With no failback
To configure MPxIO for HP storage arrays, you must add information to the /kernel/drv/
scsi_vhci.conf file.
1. Use a text editor to modify the configuration file. For example:
# vi /kernel/drv/scsi_vhci.conf
2. Change load balancing to none:
load-balance="none";
3. Change auto-failback to disable:
auto-failback="disable";
