4 Network boot Updating boot code with BCU commands Use the following procedure to update boot code using BCU commands. 1. Download the boot code image zip file (brocade_adapter_boot_fw_.zip) from the Brocade adapters website to a folder on your local drive using the following steps: a. Go to the adapters website at www.brocade.com/adapters. b. Navigate to the adapters Downloads page. c. Select your operating system from the Downloads list to display appropriate download files. d. Download the boot code image from the "Boot Code" area. 2. Extract the boot code image file. 3. Enter the following BCU command: bcu boot --update -a where: -a ID of the adapter (adapter) name of firmware image file Indicates that the boot code should be updated on all installed Brocade adapters found on the host. Note that the adapter identification (ad_id) should not be specified if the -a option is specified. Network boot The Network or the preboot eXecution environment (PXE) boot feature allows a host to boot its operating system from a system located somewhere on the Ethernet LAN instead of the host's local disk or over the SAN. Booting from a remote LAN location provides the obvious advantage of recovering quickly from a host or adapter malfunction. With PXE BIOS enabled on the adapter for a specific port ID (or a VLAN ID for a specified port), replacing an old host with a new one involves installing the adapter from the old host into the new one with the same configuration, then booting the new host. The host's operating system automatically boots from the remote LAN device. NOTE Enabling VLAN during network boot requires support from the operating system and has not been fully validated due to operating system limitations. Although fast recovery from a malfunction is a big advantage, following are considerations for the host and adapter, depending on the replacement situation: • Even though you install a similar host, the new host may require unique System BIOS options and other settings, or internal IDE drives may need to be disconnected or disabled to initiate a network boot. • If replacing the Brocade adapter in a host with a similar Brocade adapter, you will need to reconfigure the adapter to boot from the appropriate remote boot device. • If replacing a host with a different model, you may be prompted to install the adapter driver for the existing adapter. 120 Brocade Adapters Installation and Reference Manual 53-1002144-01
