Hello all,
I configured these 3 servers two for storage one a controller.  They worked fine here.  Move them to the data center and now can’t get the Secondary to sync.  If I push VM to the secondary it works.  But takes a long time because the secondary has no LV and has to create the disk and pull all data. Before I move it it was keep them both in sync and I could move without an issue.  

How do I fix this?  Do I need to assign the resource to the secondary?  it worked before not hot sure what I am missing. Yes I know ve3 is still connecting, changing the 10Gbe interface on that box right now, but it is not for storage anyway.

Thanks,
Jason
