5.6.3.2
IB fabric Items that are also checked during healthcheck
Based on
iba_report -o errors -o slowlinks
:
❥
PMA error counters on all IB ports (HCA, switch external and switch internal)
checked against configurable thresholds.
❑
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).
❥
Link active speed/width as compared to Enabled speed.
❑
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.
❥
Side effect is the verification of SA health.
