ServerNet Cluster. This section also contains replacement procedures for the main
hardware components of a ServerNet cluster.
This section contains the following subsections:
Troubleshooting Procedures
See Table 7-1 and Table 7-2 for a list of problems and recovery actions for ServerNet
cluster components. For a general approach to troubleshooting, read the
Troubleshooting Tips on page 7-1.
This section does not include common troubleshooting information for NonStop
S-series servers. Instead, refer to the NonStop S-Series Hardware Support Guide or
the CSSI Web. (Click Start>Programs>Compaq TSM>Compaq S-Series Service

Troubleshooting Tips
As you troubleshoot ServerNet cluster problems, keep in mind:
•
Sometimes it can be difficult to determine if a problem is related to faulty hardware,
faulty software, or both. In general, check the software first.
•
Use the TSM Service Application as your first method for obtaining information
about a problem. In many cases, the TSM Service Application not only identifies
the problem component but can tell you how to fix it.
•
To troubleshoot effectively, use more than one tool. For example, you can use
TSM, SCF, and a guided procedure to check the status of an Expand-over-
ServerNet line. Using all three methods allows you to compare the information
returned by each method.
•
If possible, gather information about a problem from multiple perspectives. The
view of a ServerNet cluster can change significantly from one node to another, so
