Host not booting from remote LUN
If the host system where the adapter is installed does not boot from the remote boot LUN, refer to
the following descriptions of possible causes and recommended actions to help resolve the
problem.
Possible Cause: Boot over SAN is not configured correctly.
Action: If booting the host from a remote boot device, verify whether “boot over SAN” configuration
is complete and correct. For example, verify the following:
•
A zone is created on the attached switch that contains only the PWWN of the storage system
port for the boot LUN and the PWWN of the adapter port.
•
BIOS or EFI is enabled to support boot over SAN from a specific adapter port.
•
BIOS or EFI is configured to boot from a specific LUN.
•
The host’s operating system, adapter driver, and other necessary files are installed on the boot
LUN.
Boot devices not available in host’s Boot Manager menu
Fibre Channel attached boot devices do not appear in the EFI Boot Manager menu or a boot device
appears, but it is not functioning. Following are descriptions of possible causes and recommended
actions or fixes for the problem.
1. Possible Cause: The adapter is not seated properly in the host system.
Action: Select the EFI Shell from the EFI Boot Menu and use the devices command to
determine if EFI has detected the Brocade adapter.
A Brocade adapter will have “Brocade Fibre Channel” in the device name. A CNA will also have
“Brocade Ethernet Controller” in a device name.
If the adapter is not listed, perform the following steps:
•
Reseat the adapter.
•
Replace the adapter with an adapter in known working condition to determine whether
there is a host connector malfunction.
2. Possible Cause: Adapter connector problems in host.
Action: Perform the following steps.
a. Reseat the adapter.
b. Replace the adapter with an adapter in known working condition to determine whether
there is a host connector malfunction.
c. Reinstall the adapter in a different host connector.
