Action: If you are installing the brocade_driver_linux_<versions>.tar.gz driver package, the driver
module compiles on the system during installation. If driver build errors result when you install the
package, verify that the appropriate distribution kernel development packages are installed on your
host system for the currently running kernel. These packages should include the gcc compiler and
the kernel sources. If these are not installed, you will need to install them through your Linux OS
Software Management tools or reinstall the operating system before you can continue the driver
installation. Be sure to “install everything” including the developer library options.
UEFI boot problems
This section describes problems that may occur when using the Brocade adapter and unified
extensible firmware interface (UEFI) for booting a host system from a remote storage device (boot
over SAN). Possible causes and recommended actions to help resolve the problems are provided.

On some IBM UEFI based systems, Hard Disk 0 is not present after Legacy Only option in boot
manager and system will not boot as local disk or over SAN.
Possible Cause: Hard Disk are not present in the boot manager list.
Action: Follow these steps:

2. Select Boot Manager and press Enter.
3. Select Add Boot Option and press Enter.
4. Select Legacy Only and press Enter.
5. Press Esc to return to Boot Manager.
6. Select Change Boot Order and press Enter.
7. Select the existing Boot Order and press Enter.
8. Select Legacy Only and press the + key to promote the boot order to a position above the local
device that contains the operating system (typically, this would be above Hard Disk 0). Press
Enter.
9. Confirm that Hard Disk ‘x’ is present in the list. If not, return to step 3 and add Hard Disks to
the boot order.
10. Select Commit Changes and press Enter.
