Enabling MPxIO
To enable MPxIO for HP storage devices, the appropriate information for
device-type-scsioptions-list
must 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
/dev/rdsk/c4t600508B400107271000060000C4A0000d0s2
