Seeing UNRESOLVED FAULT DETECTED alarms seen when using fanout model which was not happening on previous versions- Why is this happening and how can I correct this
 

Environment

Release: Spectrum 10.2.3 and below
Component:

Resolution

In 9.4.3 changes where added for fanout that each connection to it will be treated as a separate fault record, so in case if all the devices connected to fanout goes down for each fault record fault isolation will generate multiple unresolved alarms on FI model except for the fault record having an alarm already existing.


There was an issue with fanout as it can find root cause on any of the device in fault record which might not be appropriate if fault records are not separate. It led to above changes in Fanout.


On 10.2.3 patch Spectrum_10.02.03.D424 has been produced to resolve the issue of seeing UNRESOLVED FAULT DETECTED alarms seen when using fanout model.
