Linux Multipathing
Physically connect HBA to disk array.
Create LUN on disk array (50 GB in this case).
Reboot server to see new LUN. Note 2 separate device files with same size. This is normal.
Reboot again and interrupt the boot process and enable BIOS on the HBA card by pressing Control-Q.
Find disk device names (select sdc and sde)
