IsUnresponsive flag is set to FALSE on an event of Domain Manager restart

Issue/Introduction

The device IsUnresponsive flag is set to FALSE on an event of Domain Manager restart.

Symptoms:

This issue specifically occurs on the dynamically modelled devices (with setting for Connectivity-Polling via External Poller) 

Environment

Smarts - 10.1.X

Cause

By Smarts design, the default value of the "IsUnresponsive" is always FALSE and this is set through the internal computation via the "IsUnresponsive_internal" and this computation happens through standard ICMP & SNMP monitoring.
Further, during the restoration of the domain (on an event of restart), there is a driver that sets IsUnresponsive from IsUnresponsive_internal is overwriting TRUE value to FALSE after the value (IsUnresponsive) is restored from the RPS.

Resolution

• If the Domain Manager topology is hosting dynamically modelled devices, and no devices monitored via ICMP-SNMP:
  • Please raise a case with Broadcom Support to disable the monitoring drivers to avoid this issue on an event of restart. 

 

• If the Domain Manager topology hosts both dynamically modelled devices and actual ICMP-SNMP monitored devices:
  • You may have to update these values with manual intervention (via API or dmctl commands) for dynamically modelled devices, and the ICMP-SNMP devices would get their respective values on subsequent polling cycles accordingly.
