3. Use the BCU commands, HCM features, and host operating system commands described in
Chapter 3, “Tools for Collecting Data” to gather data for resolving problems.These tools include
event logs, operating statistics, and diagnostics.
4. Consider these factors when isolating and resolving the problem:
•
Can the issue be resolved using the latest supported combination of host system BIOS,
operating system, operating system updates, or adapter drivers?
•
Refer to “Software installation and driver packages” and “Operating system support” in
Chapter 1 of the
Adapters Installation and Reference Manual for details on driver
packages and operating system support. Also download the latest release notes from the
Brocade adapters website using the following steps:
a. Go to the adapters website at www.brocade.com/adapters .
b. Navigate to the adapters Downloads page.
c. Select your operating system from the Downloads list to display appropriate
downloads.
d. Download the release notes from the “Documentation” section.

Does the issue persist when the adapter is installed in a different platform or blade server
or connected to a different switch port?
•
Does the problem persist if using a different SFP or cable (stand-up adapters)?
•
Can this problem be reproduced on one or more adapters, ports, or host system? Can you
identify specific steps that consistently reproduce this problem on one or more hosts?
•
Is the problem documented in release notes for the adapter, operating system, or host
system BIOS?
•
Is the problem documented in release notes for the switch and target storage system?
•
Is unexpected behavior intermittent or always present?
If the problem is in a Fibre Channel or FCoE switch, storage device, or in connectivity between
these components, refer to the documentation, help systems, or service providers for that
equipment.
5. If you cannot resolve the problem, gather and provide problem information to your adapter
support provider for resolution.
NOTE
If troubleshooting information in this manual does not resolve problems, check the installed version
of the adapter (chip revision) and driver (firmware version) using the BCU adapter --query command.
To use this command, refer to
“Using BCU commands” on page 65. Also download the latest release
notes from the Brocade adapters website at www.brocade.com/adapters and look for known
problems relating to the adapter and driver versions. On the adapter website, navigate to the adapters
Downloads page, and then select your operating system from the Downloads list to display
appropriate downloads or download the ISO image.
