I have 2 windows 2003 servers running in a cluster and i am attempting to increase the bandwidth to them. I recently purchased 2x Extreme Networks x450a core switches and stacked them. Until now i have had the 2 LAN Nic's on my cluster servers (each server has 2x INTEL PRO 1000 PM) teamed using ALB but i started testing out using LACP. I created the LACP on the switches and turned on link aggregation on the teams and everything seemed to run fine. But now i keep getting event logs showing that the secondary link on the server disconnected and then rejoins.
First i get notification that the cluster lost connection with my LAN on the opposite server, then i get Event logs for iANSMiniport ID: 13 and 14 indicating:
13: The Intel(R) PRO/1000 PM Network Connection has been deactivated from the team.
14: Secondary Adapter has rejoined the Team: Intel(R) PRO/1000 PM Network connection.
Each time it does this i get a momentary packet loss to the server. Eventually after about 24 hours. or so the server finally stops responding on its cluster IP and When i look at my team, one of the cards has entered Standby even though it should be active.
At first i thought it was a physical problem with 1 server in the cluster so i failed it over and as soon as i fail it to the backup server the same thing occurs on my backup. At this point I'm better off going back to ALB but i want to be able to resolve this issue to get more bandwidth to the server.
