Oracle has implemented a ROM BIOS extension for its HCA cards. This extension, called XgBoot, enables you to use Oracle virtual I/O resources as boot devices for the server. You configure the system BIOS to include XgBoot in the boot order, and configure the Oracle Fabric Interconnect to make sure virtual resources are bootable.
Whatever remote booting process you select, you use the following high-level steps:
Set up the boot volume.
You need the boot image to be available on the network.
Configure bootable I/O resources on the Oracle Fabric Interconnect.
For SAN booting, this is a VHBA configured as bootable. For PXE boot, you use a bootable VNIC. Either resource must be assigned to a server profile that is bound to the server that boots remotely.
Configure the server.
HCAs on the server must have compatible firmware, and their option ROM must be enabled.
Connect the server profile on the Oracle Fabric Interconnect to the server.
Set the server profile to SAN boot (sanboot=).
You can choose any one of the following boot methods:
