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 refer to the latest release notes on
.
•
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?
•
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 of 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 (fw version) using the BCU adapter --query command. To use
this command, refer to
“Collecting adapter data using BCU commands”
on page 52. Also refer to
release notes posted on the Brocade adapter website for known problems relating to the adapter
and driver versions. The HBA website is
