Just Another IT blog: RDM Disk corruption on Microsoft Failover Cluster
Recently I’ve been working on a fresh new vSphere 6 environment and we wanted to test a new functionality, vMotion of clustered guest VMs with RDM. We created and configured Windows Server Failover Cluster solution (WSFC) in accordanced with VMware’s Best Practices and then vMotion it to another hosts, as expected successfully !!! Then we decided to change the Multi Path Policy of the RDM disk to Round Robin, already supported since vSphere 5.5, when we vMotion the clustered guest VM ,in this specific scenario, we faced a disk corruption on the WSFC solution.
