Appendix B Troubleshooting B-9
B.3.4 Using the fmdump Command
The fmdump command displays the contents of any log files managed by the module
called Fault Manager.
This example assumes there is only one fault.
B.3.4.1 fmdump -V Command
You can obtain information in more detail with the -V option, as shown in the
following example.
At least three lines of new output are delivered by the -V option:
■ The first line is a summary of the information that you have seen before in the
console message, including the timestamp, UUID, and message ID.
■ The second line is a declaration of the certainty of the diagnosis. In this example,
there is a 100 percent probability that the failure is in the indicated ASIC. As
another example, if the diagnosis were to involve two components, you would
see two lines here with 50% on each line.
■ The "FRU" line declares the part that must be replaced to return the server to a
fully operational state.
■ The "rsrc" line identifies the component taken out of service as a result of this
fault.
