General adapter problems
Driver and operating system installation failure on boot LUN
Installation fails when installing drivers with the driver update disk (DUD) and an installing
operating system to a remote LUN being used for booting over SAN.
Possible Cause: The appropriate driver update disk (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: Download the appropriate DUD for your host platform from the Brocade adapters website
using the following steps.
1. Go to the adapters website at www.brocade.com/adapters.
2. Navigate to the adapters Downloads page.
3. Select your operating system from the Downloads list to display appropriate downloads.
4. Download the dud from the "Driver Update Disk (DUDs)" area.

"29" is the device handle, and will be different in most systems. More than one Brocade
adapter may display.
b. Use the EFI shell dh command to display additional information about each Brocade
adapter. This will include any attached Fibre Channel disk devices. For example, you would
enter the following for the HBA or Fabric Adapter port configured in HBA mode with device
handle 29:
Shell> dh -d 29
The following displays:
29: PciIo ScsiPassThruExt BusSpecificDriverOverride DevPath
(..P0A08,300)/Pci(0|0)/Pci(0|0))

Drv[26] : SCSI Bus Driver
...
Child Controllers
Child[70] : SCSI Disk Device
Child[71] : SCSI Disk Device
Child[72] : SCSI Disk Device
The SCSI Disk Devices under "Child Controllers" are the LUNs that the Fibre Channel
adapter can access.
c. If an expected Fibre Channel attached disk does not appear in the "dh -d" list for a
Brocade adapter, check the cabling, the adapter's link status LEDs, and the Fibre Channel
switch configuration.
NOTE
The Brocade adapter port may have been disabled with the EFI shell drvcfg command. Use the
drvcfg -s shell command to check the enabled status and configuration of the port, including
the requested speed. After entering drafted -s, select the appropriate adapter from the Adapter
List screen and press Enter to view and modify port properties.
