Cluster will not fail over when all paths to a disk fails on active node but not inactive node.
Posted on 2013-06-26
We are setting up a new Server 2008 R2 cluster with two nodes. Each node is presented two LUNs from our SAN, one for the Quorum drive and another for application data.
We were testing failover today and if we removed all paths to the application data LUN for ONLY the active node but not the inactive node, we expected the cluster to failover to the inactive node since it was still able to see the LUN. Instead, however, the cluster did not fail over to node 2 instead it stayed active on the first node but simply marked the application LUN as "failed" and would not failover to the inactive node.
Does anyone know if this is expected behavior and if not, how to fix?
