Troubleshooting HyperFabric
Running Diagnostics
Chapter 6136
Diagnostics can be run on many of the HyperFabric components by using
the clic_diag command. If the HyperFabric subsystem is still not
usable, contact your HP support representative with the diagnostics data
generated using the clic_diag command described below.
The clic_diag Command
Use the clic_diag command to run the following diagnostics:
• Probe a specific remote node.
• Dump and format trace data.
• Set the tracing level for the HyperFabric software and the firmware.
Two versions of the clic_diag command are available:
• The command line version. In this version, you specify the command
and the parameters you want to run (which are described below).
• The interactive version. To use this version, specify only the
command name (clic_diag). Then, you are prompted for the same
kinds of information you specify when you use the command line
version.
If you include /opt/clic/bin in your PATH statement, you can run the
command as it is shown below. Otherwise, you must include
/opt/clic/bin as part of the command name (that is,
/opt/clic/bin/clic_diag).
You must be logged in as root to run this command.
The command line syntax is as follows:
clic_diag [-r remote_node_name ] [-T trace_level ] [-D TCP_IP]
[-C TCP_IP] [-B
trace_buffer_size ]
[-F
trace_file_size ] [-d adapter_ID filename ] [-?]
Note that some of the lines in the above syntax are indented for
readability purposes only. When you actually type the command, you do
not indent anything.
The command parameters are as follows:
