Use the hp provided driver and enable multipath support by running /opt/hp/src/hp_qla2x00src/set_parm.

See the attached file.

Not sure that Oracle Linux is officially supported by HP

Access HP website & download the latest proliant support pack (v8.11 i think) this kit is a tar.gz pack ... unpack it onto a temp dir on your server...

# cd ./compaq/csp/linux
# ./install811.sh

A GUI installation application will display. This is the installation script to update/install a number of HP management tools including HP supported NIC drivers AND Qlogic HBA driver. During the configuration of the HBA driver ... ensure that you select the Failover option. Once the PSP kit is fully installed, allow a system reboot. The new QLA driver will be built into the initrd & a new grub entry added. This should get your system working as expected (assuming it will install on an Oracle Linux system :-) )

You can see a list of the servers certified with Oracle Linux at http://h18004.www1.hp.com/products/servers/linux/hpLinuxcert-oracle.html

http://h18004.www1.hp.com/products/servers/linux/hplinuxcert-oracle.html works better.
(The only difference is a lowercase vs uppercase "L".)

The mulitpath.conf file is usallly not present by default. If you can't start multipathd, you'll probably need to install the multipath-tools rpm package.

If you install the HP version of the QLogic driver you need to run the /opt/hp/src/qla2x00src/set_parm utility to setup failover.

Until you configure one or both of these options (if you setup multipathd and are using the HP QLogic driver disable driver failover) you will see multiple instances of the same LUNS
