Network Subnet discovery using the Discovery quick start throws error "Failed to get 'subnet_discovery_queue' recordfor MID Server 'xxx' and router IP 'xxx' Description Network Subnet discovery using the Discovery quick start throws error "Failed to get 'subnet_discovery_queue' recordfor MID Server 'xxx' and router IP 'xxx'

Steps to Reproduce

0 → Create a MID server cluster with two MID Servers 1 → Navigate to "Discovery → Home". 2 → Click on "Discovery Quick Start" UI link. 3 → Add only one MID server from the MID cluster 4 → Complete the steps for creating the "Subnet Discovery" schedule and run 5 → In the discovery logs for the status see the error "Failed to get 'subnet_discovery_queue' record for MID Server 'xxx' and router IP 'xxx'"

Workaround 1. Go to "MIDClusterManagementUtil" business rule

2. Inside checkPrecondition function, add the following code at the top:

function isNotSubnetDiscovery() { return (discover != 'Subnet'); } var discover; var discoveryStatusGlideRecord = new GlideRecord('discovery_status'); if (discoveryStatusGlideRecord.get('sys_id', current.agent_correlator + '')) discover = discoveryStatusGlideRecord.discover + '';

3. Add the following to the end of the "return" statement: "&& isNotSubnetDiscovery()"
