bios
Enables the basic input/output system (BIOS) in preparation for Boot Over SAN. The BIOS is the
firmware code that, when first powered on, is a type of boot loader.
NOTE
Refer to the Brocade Adapters Installation and Reference Manual for more information about
configuring BIOS.
Synopsis bcu bios --query <port_id>
bcu bios --enable <port_id> [-s speed] [-o auto|flash|firstlun] [-p pos] {-b pwwn,lun}*
bcu bios --disable <port_id>
Description You must enable BIOS to support boot over SAN for a port. If disabled, the host system cannot boot
from Fibre Channel disk drives. BIOS must be enabled on only one adapter port per host in order to
boot from SAN. The default setting for the boot BIOS is enabled.
The port ID can be any of the following:
• Adapter ID
• Port ID
• Port WWN
• Port name
• Port hardware path
Operands --query Queries the boot-over-SAN configuration.
port_id Specifies the ID of the port for which you want to display information.
--enable Enables the boot over SAN configuration.
port_id Specifies the ID of the port for which you want to set the port’s boot from SAN
attributes.
s speed Specifies the port speed as auto-negotiate.
o auto|flash|firstlun
Specifies the following options for obtaining boot LUN information:
• auto - Enables auto-discovery. When enabled, the boot LUN identification
is provided by the fabric.
• flash - The adapter obtains the boot LUN information from flash memory.
Values are saved to flash when you configure them and save them
through the BIOS Configuration Utility, HCM, and BCU.
• firstlun - The host boots from the first LUN visible to the adapter that is
discovered in the fabric.
p pos Specifies the position for storing the boot LUN information in the -b pwwn, lun
operand. The range is 0-3. The LUN information specified in position 0 is used
first to boot from SAN, then information specified for positions 1, 2, and 3.
