Brocade Communications Systems 804 manual Pre-boot configuration

3 Boot over SAN

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 Figure 9. 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 “Configuring Boot over SAN” 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 “boot” on page 133 for details about this command.

3.Configure the zone on the switch using the Fabric OS zoneCreate command. Refer to the Brocade Adapters Installation and Reference Manual or the Fabric OS Administrator’s Guide for more information about creating zones.
