BMC Discovery 12.0
When trying to test the Discovery to CMDB synchronization connection, the error appears:
"The connection test failed: ERROR (90): Cannot establish a network connection to the AR System server; Connection timed out "
The AR90 error occurs when the client (in this case, Discovery) cannot connect to AR Server. Unfortunately Discovery has no way to tell why it can't connect.
Please log into the Discovery appliance command line and try these commands:
ping [ip address of AR Server]
traceroute [ip address of AR Server]
Verify that there isn't a firewall that may be blocking the traffic.
The sync connection can be configured to use a specific port. Otherwise, a port should be assigned by the portmapper on the AR System side. Make sure the AR portmapper service is running. Even if it is, check the AR configuration to see if there is a port specified - if so, try using this in the Discovery synchronization configuration.
If the problem persists, gather the Discovery sync logs and AR/CMDB logs with API, Filter, SQL, Thread, and Plugin logs enabled. Open a support case with the CMDB support team and provide this information.
