Failover Recovery

[J Springer]

4.1.1-P1

I am working to recover a server in failover mode.

The DISCOVER is broadcast, the responsible server (#2 in this case, it's the 
server coming back on-line after an outage) handles the OFFER.

The REQUEST is sent to both servers with the server-identifier of the server 
providing the offer.

The ACKs are returned from both servers.  However, the server not responsible 
(#1) for the offer is sending its IP address as the server identifier even 
though that is not the IP address in the request.

This causes the modem to continually request until is receives the correct data 
in the ack, which only comes from the offering server, prior to receiving the 
incorrect data in the ack from the other server.

The server identifier is not in the configuration files nor is it used in any 
OMAPI calls.

Why would the [primary] server receive a server identifier with the IP of its 
partner in the request but send its own IP in the ack?  Is there another 
configuration option that might change the data in this field?

Looking back through the logs (no captures) prior to server #2 taken down, I see 
this behavior -- continual requests until the ack is sent from the offering 
server first.  The only difference between prior to the failure and after 
failover recovery is then we saw maybe 60-120 seconds for the correct ack to get 
sent first.  After recovery, it was in the hour+ range.
