Dell PowerVault MD3200i/MD3220i Important Info with Windows HA Clusters Owner's Manual, User Guide
Summary
Technical documentation for configuring IP addresses on Dell failover clusters using Microsoft Windows Server 2008 with direct-attached iSCSI storage arrays such as PowerVault MD3200i, MD3220i, MD3000i, and Dell|EMC AX/CX series. The guide explains that each host-to-storage iSCSI connection requires a different subnet address for successful Failover Cluster Validation. It provides correctly configured examples with four separate IPv4 subnets for four NICs across two cluster nodes, and illustrates misconfigured scenarios that cause validation test failures. Intended for IT administrators and system engineers deploying Dell storage clusters.

Dell Failover Clusters With Microsoft Windows Server 2008 Operating System—Important Information Configuring IP Addresses for Dell Failover Clusters with Direct-Attached i SCSI Storage Arrays To successfully validate Dell failover cluster configurations based on direct-attached i SCSI storage arrays (for example, Dell Power Vault MD3200i, Dell Power Vault MD3220i, Dell Power Vault MD3000i, Dell|EMC AX-Series, or Dell|EMC CX-Series), the failover cluster requires a different subnet address for each host-to-storage i SCSI connection. If the two IP addresses that are used for a host-to-storage i SCSI connection are configured on the same IP subnet, and if you run the Failover Cluster Validation wizard, the Validate Network Communication test fails. Figure 1 is an example of a Dell failover cluster configuration with four different IPv4 subnets for the four NICs. If you run the Validate Network Communication test on this cluster configuration, the test is successful.

Frequently Asked Questions
What is required for a successful failover cluster validation with direct-attached iSCSI storage?
Each host-to-storage iSCSI connection must use a different subnet address.
When does the 'one subnet per iSCSI connection' rule apply?
It applies to multi-node direct-attached configurations and those using IPv6 or single iSCSI connections per host.
How do I configure a volume mount point in a Dell Failover Cluster?
Initialize the logical disk, add it to the Available Storage pool via the Failover Cluster Management Console, create the partition/mount point, and then configure the cluster dependency.
