NSM DB Replication can time-out if two NSM Servers are connected over WAN link.

Solution:

NSM 2007.2 and above performs a real time replication of NSM DB to secondary server. The initial replication starts once the second server is connected to the primary server. The replication might timeout if the heartbeat between the servers fails.  For slow connections you can change the heartbeat, see example below.

  1. Edit the file haSvr.cfg - vi /usr/netscreen/HaSvr/var/haSvr.cfg

  2. Change the heartbeat timeout and threshold 
    highAvail.heartbeatInterval                   30 (default is 15 seconds)
    highAvail.timeoutHeartbeats                   10 (default is 4)

  3. Restart HA Services on both primary and secondary NSM Servers for new values to take affect.

To check the replication status, run the script /usr/netscree/HaSvr/utis/haStatus. This will show the status of each Server and the sync status.
