Adapter firmware
A single, updatable boot code image, stored in the adapter option read-only memory (option ROM)
memory, contains all boot code for supported host platforms.
By default, BIOS and UEFI are enabled on adapter ports for boot over SAN.
All Brocade adapters installed on a host system must use the same boot code version.
To keep drivers and boot code synchronized, be sure to update your adapter with the latest boot
image after you install or update adapter driver packages. Be sure to update drivers before updating
the boot code.
Updating boot code through HCM is not supported on VMware ESXi servers. Use the BCU boot -
-update command instead.
View the BIOS that displays on your system screen during hardware reinitialization, just before you
are prompted to press Ctrl and B or Alt and B to enter the Brocade Configuration Utility.
Enter the bcu adapter --query command. The installed BIOS version displays in the Flash
Information section of the command output.
View the adapter Properties panel in HCM. To view the panel, select the adapter in the device tree,
and then click the Properties tab in the right pane.
Download the latest boot code from the "Boot Code" area on
Extract the boot code image file.
Enter the following BCU command:
bcu boot --update <ad_id> <image file> -a
where:
<ad_id>
ID of the adapter (adapter)
<image file>
Name of firmware image file
-a
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.
