You can setup a SPARC or an x86 server with the Oracle Solaris OS to boot from a FC disk device. On a SPARC server, the installer configures OBP automatically. On an x86 server, you must configure the HBA BIOS manually to boot the Oracle Solaris OS from an FC device.
You can install the HBA hardware by following the instructions in the related Oracle HBA installation guide available at SAS PCIe RAID HBA Hardware Installation and Removal.
