Common Operations and Options
The Health Check and Baselining tools support the following options to select
the operations to be done by the tool:
-b - perform a baseline snapshot of the configuration
-e - perform an error check/health analysis only
If neither option is specified, the tool performs a snapshot of the present
configuration, compares it to the baseline and also perform an error check/health
analysis.
Use of both -b and -e on a given run is not permitted.
The typical use of the tools is to perform an initial error check by running the -e
option. Review the errors reported in the files indicated by the tools. Once all
the errors are corrected, perform a baseline of the configuration using the -b
option. The baseline configuration will be saved to files in
$FF_ANALYSIS_DIR/baseline (the default of
/var/opt/iba/analysis/baseline is set via
/etc/sysconfig/fastfabric.conf). This baseline configuration should
be carefully reviewed to make sure it matches the intended configuration of the
cluster. If it does not, the cluster should be corrected and a new baseline run.
For example:
fabric_analysis -e
errors reported could include links with high error rates, unexpected low speeds,
etc. Correct any such errors then rerun fabric_analysis -e to make sure
there is a good fabric.
fabric_analysis -b
The baseline configuration will be saved to $FF_ANALYSIS_DIR/baseline.
This will include files starting with links and comps. These will be the results
of iba_report -o links and iba_report -o comps reports respectively.
Review these files and make sure all the expected links and components are
present. For example, make sure all the switches and servers in the cluster are
