Issue/Introduction

Symptoms:




SystemRedundancyAt Risk Alarms not are displayed in Smarts IP Availability Manager
Switch in the SystemRedundancyGroup of Smarts is powered down

Environment

VMware Smart Assurance - SMARTS

Resolution

This is expected behavior and the Smarts IP Availability Manager product is behaving as designed. For the SystemRedundancyAt Risk alarm to be generated the following must be met based on the following primary logic for AtRisk:

NumberOfComponents - NumberOfFaultyComponents <= AtRiskThreshold

As above condition does not hold true, an event is not generated.

The complete AtRisk logic checks for few other alarms and parameters as well before giving AtRisk as follows:

if (NumberOfComponents > 0)
check (!IsGroupPartOfSingleUnresponsiveSystem &&
IsAnyComponentDown &&
!IsEveryComponentDown &&
NumberOfComponents - NumberOfFaultyComponents <= AtRiskThreshold);
