    So I have a corrupted hub.sds file and while looking thru the hub.log I noticed it was saying things like:

    Dec 3 12:55:37:647 [2548] 1 hub: nametoip - /NMS/OLDCLINETA/clientA_HUB/topology_agent failed rc=4(not found)
    Dec 3 12:55:37:647 [2548] 1 hub: nametoip - /NMS/OLDCLINETB/clientB_HUB/topology_agent failed rc=4(not found)

    These hubs have been gone for many months so wondering how do we clean this up? How do we remove all references to old hubs and the discovery_agents b/c as per the log from today its still trying to find these old entries. 

    I looked in the discovery_server probe utility list and don't see anything that allows to remove specifically 1 discovery agent.


    What is the right way to do this? 

    TIA...

    this could be caused by entries in the CM_DISCOVERY_AGENT table.
    Review the data in this table and delete any old entries there for discovery_agents.

    Also, make sure you do not have any old settings for tunnels or static mappings to these hubs.

    Hi Gene,
    So manually delete them via SQL queries to this table in the DB or are there any probe utilities that will do this for me?

    Okay I remember now. I had a case for this a long time ago. I can use the following:


    select * from CM_DISCOVERY_AGENT order by hub

    /* Find the da_id # in the table above and then enter it at the end of the line below to delete that discovery_agent
    exec P_CM_REMOVE_DISCOVERY_AGENT @da_id =

    exec P_CM_REMOVE_DISCOVERY_AGENT @da_id =56
    exec P_CM_REMOVE_DISCOVERY_AGENT @da_id =207

    Hopefully this is still the same method in 9.2.0's discovery server?
    BTW Could I stop discovery_server, drop this table and then start discovery_server? Would it get re-populated once all the discovery_agents 'check-in' again? 
    There are over 60 extra entries in this list today. Looking for easiest way to clean this up fully.

    BTW just FYI for the clean up I just ran the
    exec P_CM_REMOVE_DISCOVERY_AGENT @da_id =56
    command on all the ID's after stopping the discovery_server, discovery_agent and topology_agent on the primary hub. Then started it all back up and everything got re-created. So all good for now..
