How to use this manual for troubleshooting
An adapter, such as an HBA or CNA, is one component of a larger network consisting of switches,
storage devices, host systems and the cabling and connections to these components. Although
there may be a problem in the adapter or an adapter component, the problem could also originate
in another network component or connections between these components. Before removing and
replacing adapters, launching adapter diagnostics, or even gathering statistics on adapter
operation, it is important that you perform the following tasks:
1. Fully describe the problem and gather complete information about the symptoms that suggest
“Gathering problem information”
2. Isolate or resolve the problem by first using information in
Chapter 2, “Isolating Problems”
.
Adapter problems are organized under the following categories:
•
“General HBA and CNA problems”
•
•
“Ethernet network interface problems (CNAs only)”
•
“FCoE and Fibre Channel problems”
•
“CEE network problems (CNAs only)”
Search through the list of problems in
on page 5. Problems are organized in the table
by problem title, category, and whether the problem is operating-system-specific. Click on a
problem to go to the chapter section containing details of possible causes and actions for
resolution.
Each problem section in Chapter 2 provides a complete description of the problem, possible
causes, and actions for resolution. Fixes and actions may reference BCU commands, HCM
features, and host operating system commands. These are described in
