Devices reachable from primary spectroserver but unreachable from the secondary spectroserver, on fault tolerance

Products

• CA Spectrum

Issue/Introduction

We have a primary/Secondary failover SS scenario. Devices are reachable from Primary OK but when failover occurs, some devices are not reachable by Secondary server location, and Lost Contact alarms generate. They clear when back on Primary and reachable. Can we poll devices from Secondary server while it is still inactive? 

 

 

 

Environment

Release : 20.2

Component : Spectrum Core / SpectroSERVER

Resolution

This would be an ER request. There is no such current mechanism to view polling results from Secondary server (even if secondary_polling=yes is active in .vnmrc) due to OneClick can only connect to one main server for polling results views. Once failed over to Secondary, then you can see polling results of the devices. For any devices unreachable the network team would want to assist in determine the reason they are not reachable and resolve alarms when Secondary is active. 

As an unsupported alternative, you can also try scripting the command "snmpget" and poll simple OID like "sysuptime" or "Sysdescr" on the device, just to verify its SNMP agent is responding. This would be done outside Spectrum environment in Command Line scripting.
