chassis_analysis

(Switch): The chassis_analysis command has the following usage:
chassis_analysis [-b|-e] [-s] [-d dir] [-F chassisfile] [-H
'chassis']
-b - baseline mode. The default is the compare/check mode.
-e - evaluate health only, default is the compare/check mode.
-s - a save history of failures (errors/differences).
-d dir - the top level directory for saving baseline and history of failed checks.
The default is /var/opt/iba/analysis.
-F chassisfile - the file with the chassis in the cluster. The default is
/etc/sysconfig/iba/chassis.
-H chassis - a list of chassis on which to execute the command.
For example:
chassis_analysis
The chassis analysis tool checks the following for SilverStorm IB chassis:
Chassis configuration (as reported by the chassis commands specified in
❥
FF_CHASSIS_CMDS in fastfabric.conf).
Chassis health (as reported by the chassis command specified in
❥
FF_CHASSIS_HEALTH in fastfabric.conf).
5-76
Counters are cleared each time a healthcheck is run, each healthcheck
reflects a counter delta since last healthcheck.
Typically identifies potential fabric errors (symbol errors, etc).
May also identify transient congestion (depends upon counters monitored).
Identifies links whose active speed/width is < min(enabled speed/width on
each side of link).
This typically reflects bad cables or bad ports or poor connections.
