Bios Boot Problems - Dell Brocade Adapters Troubleshooting Manual

Driver preinstallation problems
The following problems may occur when drivers are preinstalled to your Windows host system driver
store.
Preinstallation failed when attempted twice in a row without inserting adapters
Preinstallation of drivers fail when attempted twice in a row and adapters are not inserted in the
system.
Possible Cause: Windows restricts upgrading a preinstalled driver before installing the hardware.
Action: Remove the driver package that was preinstalled earlier, then retry preinstalling the new
driver package.
Preinstallation with adapter installed in system does not update the installed driver image
Preinstallation does not update the currently installed driver image when an adapter is already
present in the system.
Possible Cause: This is an expected behavior in Windows. You must install (instead of preinstall)
the driver to update the currently loaded driver if the hardware is already present on the system.
Action: Reinstall the driver using brocade_install.bat installer script command with the
FORCED_INSTALL=TRUE option.
Installing Windows 2008 R2 DUD on UEFI system results in offline disk
Installing the Windows 2008 DUD and operating system on a formatted UEFI system disk that you
are configuring as a bootable device results in an offline disk.
Possible Cause: This behavior is working as designed by Microsoft if the disk is formatted, as the
default SAN POLICY is OFFLINESHARED, which marks SAN disks as Read Only during setup to
ensure that no data center related data are accidentally overwritten.
Action: Use an unformatted "fresh" disk for DUD and operating system installation. Also refer to the
"How to Use Windows Setup to Install Windows with UEFI Support" section of the Microsoft UEFI
Guide.

BIOS boot problems

This section describes problems that may occur when using the Brocade adapter and Basic
Input/Output System (BIOS) for booting a host system from a remote storage device (boot over
SAN). Possible causes and recommended actions that may fix the problems are provided.
Driver and operating system installation failure on boot LUN
When installing drivers using the driver update disk (DUD) and an operating system to a remote
LUN being used for booting over SAN, the installation fails.
Possible Cause: The appropriate DUD may not have been used for the host operating system and
platform. For example, if the brocade_adapter_rhel53_x86_64 DUD is used during RHEL 5.3 x86
installation, installation will fail.
Action: Verify the DUD for your system using information in Chapter 1 of the Brocade Adapters
Installation and Reference Manual. Using the correct DUD, reinstall appropriate drivers and the
operating system as necessary.
