MPIO in Server 2012 R2. Second connection keeps dropping.
Posted on 2015-01-29
I have several R720 servers with dual port Broadcom BCM57810 10Gb NICS. They all have Windows Server 2012 R2 Datacenter installed with the Hyper-V role. I am trying to make iSCSI connections to a Dell/Equallogic PS6110. I have HIT 7.1 installed on the servers. I can make a single connection to the storage ok, but when I make the second connection (MPIO) , it drops shortly thereafter. I believe the issue is on the server side because we have other Dell servers that were configured by Dell and have MPIO (2 connections) working fine. Any advice on how to get the second connection to stay up? I want to cluster these nodes, but the cluster validation test keeps failing on MPIO, stating there's only a single connection to the storage.
