    I also have implemented a few HA setups with 5508, the one's with V7.6.110.0 & V.7.6.130.0

    both sometimes generate the error: 

    RF failure notification ErrorType: 32 Reason :Error: Config Sync failed on Standby for the usmdb:HA_send_usmDbMsAddToBlackList

     

    In the above post i do not see a fix or BugID for this specific message ?

    Also is this just a cosmetic message or is there a real issue with the configuration not being in sync in the HA pair.

    Redundancy Failure Event trap triggered by Controller  for the reason 'Error: Config Sync failed on Standby for the usmdb:HA_send_usmDbMsAddToBlackList,' ; this is in 7.6.130 which we just upgrade to this morning but we also saw this in 7.6.110. 

     

    Any idea when this will be fixed or can it be filtered out.  Sounds like it's a bug not a legit error.  Please advise. 

     

     

    it's interesting ... update to this post ... upgraded to CPI version 2.2.0.0.158 .. not seeing the error now.  weird. controller is at 7.6.130.

    Hi @ all,

    i have the same issue here with 5508 controller and version 7.6.120.0

     

    Seems to match bug :

    CSCun67484

    Synchronization failed on standby for the usmdb:HA_send_usmDbMsAddToBlackList task

    Anybody an idea if this problem is causing errors - or is it only cosmetical ?
