How to use this manual for troubleshooting
An adapter, such as an HBA, CNA, or Fabric Adapter 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 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
a problem exists. Refer to “Gathering problem information” on page 3.
2. Isolate or resolve the problem by using information in Chapter 2, “Isolating Problems” .
Adapter problems are organized under the following categories:
Search through the list of problems in Table 2 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.
• “General adapter problems”
• “HBA problems”
• “Network interface problems (CNA or NIC)”
• “FCoE and Fibre Channel problems”
• “DCB network problems”
• “HCM and HCM Agent problems”
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
Chapter 3, “Tools for
Collecting Data” .
