We recently setup 2 Dell PowerVault NX3000 running on the Windows Storage Server 2008 R2 Enterprise SP1 as a clustering. Let's say NAS1 and NAS2. We have 3 nodes, and 2 of the nodes setting as prefered owner NAS1 and 1 node set as NAS2. For some reason, the current owner on 1 node keeps changing and flipping over to the other node NAS1. We have reviewed our network engineeering and network setup and configuration are fine. Based on the testing we have so far, the only way to keep consistent on the current owner on that one node is both NAS01 and NAS02 connecting to one core switch (either A or B side), but this solution is only for temporary. If the core switch goes down, we need to physical move the cable to other working switch.
If anyone experiences this problem and know the the fix for this, can you kindly shed some lights for me. Also, in Windows Clustering, is there a such thing for tuning the sensisitivity/timing or some sort....
Much appreciated.
