A Troubleshooting Guide is provided to assist in debugging a specific issue. When possible, diagnostic tools are included in the document to assist in troubleshooting.

Troubleshooting Details

Examine Maintenance -> Logs -> Alerts in the BUI of the source system. There should be alerts similar to the following :

    2011-9-10 11:30:01  Began replicating 'HOMEtest' to appliance 's7120-ftlauder-a'.
    2011-9-10 11:30     Replication of 'HOMEtest' to 's7120-ftlauder-a' failed.

Click on the "information" symbol to the right of the "failed message" date. Does it specify a reason why the replication failed ?

Examine the Alert log on the target system, searching for the date and time that it failed.

If there was no alert generated, the possibility exists that the source never made contact with the target.

Here, we see that a successful replication did take place the day before.

2011-9-9 09:33:25    Finished replicating project 'HOMEtest' from appliance 's7420-ftlauder-a'.    Minor Alert
2011-9-9 09:33:08    Began replicating project 'HOMEtest' from appliance 's7420-ftlauder-a'.    Minor Alert

Was there work being performed on the network when the replication failed ? If that work has been completed, then attempt a manual replication to the target system.

Might the IP address of either the source or the target system have been changed since the last successful replication. The appliance IP addresses can not change. If done, the old replication package will need to be destroyed and a new one created.

Check for messages indicating no route to host in the system log. If those messages exist, from the CLI enter "traceroute <target ip address or hostname>"
