You must enable BIOS to support boot over SAN for a CEE port. If disabled, the host system cannot
boot from Fibre Channel disk drives. The default setting for the CNA boot BIOS is enabled. BIOS
must be enabled on only one adapter port per host in order to boot from SAN.
The port ID can be any of the following:
•
Adapter ID
•
Port ID
•
Port WWN
•
Port name
•
Port hardware path
