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”

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
