Pre-boot configuration

Any parameters flagged with pre-boot were configured using a blade system management 
application. You cannot use HCM to create or modify a pre-boot configuration. If the port has been 
pre-boot enabled:

•

The BIOS Enable option is disabled. 

•

The pre-boot configured LUNs in the LUN column are displayed as <LUN wwn> (Pre-boot), as 
shown in 

. The maximum number of user-configured LUNs supported is four, and the 

maximum number of pre-boot-configured LUNs is eight.

•

The configuration changes take affect after the next reset. 

Configuring fabric-based boot LUN discovery 

Use the following steps to configure fabric-based boot LUN discovery.

1. Set the adapter’s BIOS configuration to auto-discovery using one of the following interfaces:

•

Brocade BIOS Configuration Utility
Adapter Settings > Boot LUN > Auto Discover

•

HCM 
Refer to 

 on page 28 for instructions.

•

BCU
bios --enable <port_id> -o auto

2. Enter the following BCU command to provide the zone name and zone members to use as 

operands in the Fabric OS zonecreate command.

bcu boot --blunZone -c <cfg> -p <port_wwn> -r <rport_wwn> -l <lun_id | lun#>

Refer to 

 on page 133 for details about this command.

3. Configure the zone on the switch using the Fabric OS zoneCreate command. Refer to the
