I really appreciate your help in this and it's good to know someone else has this style configuration working. There was very little to go on as most designs involve using two 10Gbe switches which look much easier to configure but didn't make sense to me as it was just another layer of failure and costs. So in your iSCSI Initiator Devices MPIO configuration, do you only have three paths for each target? ie, from Node 1 to Node 3, iSCSI target on Node 1, would be 0.0.0.0-127.0.0.1, 11.0.3.1-11.0.3.2 and 11.0.4.1-110.4.2?upgraders wrote:You are crossing traffic so two separate sync channels and iscsi... hum I dunno I think I'd like to hear Starwind chime in. I would think you would not want to mix traffic or what that would cause (caveats) ? but yes you are right since you have two sync and iscsi and one goes down in that configuration you would not lose, but I am not sure.. perhaps that's why you can't get MIPO working?? if you used nic teaming with one IP so that failover would happen automatically that may be an option. My configuration was drawn up by Starwind a few years back and ok'ed by Anatoly so I would think if there was a better configuration he would have done it that way. Ive been running with this setup for about a month now and I am very pleased.

Did Anatoly say anything about if your sync channel fails and your iSCSI is up would cause any issues? I'm just worried about causing any split brain type issues.
