HBA problems

4. Possible Cause: There is a problem with the remote port.
Action: Verify that the remote target port (rport) is reporting itself online by comparing rport
online and rport offline statistics. Refer to “Remote port statistics” on page 59 for details on
displaying these statistics. The rport online counter should be one greater than the rport offline
counter. If not, clear the counters and try connecting to the remote port again. Verify the rport
online and rport offline statistics again.
LUN not visible from host
If the LUN from which the host system will boot is not visible from the host system, refer to the
following descriptions of possible causes and recommended actions to help resolve the problem.
1. Possible Cause: Missing or improper storage array LUN masking setting.
Action: Check LUN mapping and masking using storage array configuration tools.
2. Possible Cause: Adapter driver not loaded.
Action: The adapter driver may not be loaded. Refer to “Adapter driver installation verification”
on page 34 for methods to verify driver installation.
<CTL-B> option does not display when booting host
When booting the host, the CTL-B option does not display so that you can access the BIOS
Configuration menu.
1. Possible Cause: The adapter might not be loaded with the latest adapter boot image
(bfa_boot_fw).
Action: Download bfa_boot_fw from the HBA website (www.brocade.com/hba) and load to
option ROM on adapter using the BCU boot --upload command.
2. Possible Cause: Due to memory constraints system BIOS might not be able to execute the
Brocade adapter option ROM.
Action: Disable option ROM on several add-in cards installed in system.
No target devices found or link down! message displays in Brocade BIOS
Configuration menu
“No target devices found or link down” message displays on Brocade BIOS configuration menu
during boot device discovery.
1. Possible Cause: There is no fabric connectivity between the Brocade adapter and target, or the
target is not online.
Action: Execute the Fabric OS nsAllShow command on the attached switch to verify that the
target and the host are online in the fabric and registered in the name server.
2. Possible Cause: The target and the adapter port are not on the same zone.
Action: Execute the Fabric OS cfgActvShow command on the attached switch and verify that
the host and target are in the same zone by using either domain area members, port area
members, or port or node WWNs.
