HPC Cluster Manager may indicate that one or more nodes cannot reach the Active Directory ___domain. For example, the Domain Connectivity diagnostic may report a warning or a failure for one or more nodes. When you attempt to provision a compute node, provisioning may fail because a ___domain controller cannot be contacted. However, your Active Directory environment may contain one or more active ___domain controllers.
Cause
HPC Cluster Manager cannot contact the “preferred” ___domain controller for cluster operations. The preferred ___domain controller is identified internally for the cluster when you provide the credentials of a ___domain account in the Installation Credentials dialog box. These credentials, and the preferred ___domain controller, are used when installing the operating system, installing applications, and when adding nodes to the Active Directory ___domain.
Resolution
If you have a single ___domain controller in your Active Directory ___domain, check the network connections and make sure that the ___domain controller is started and is responding.
If you have more than one ___domain controller in your Active Directory ___domain, you can reset the preferred ___domain controller for the cluster. To do this, enter credentials again in the Installation Credentials dialog box. When you enter the credentials, the ___domain controller that responds is identified internally as the preferred ___domain controller. For more information about entering credentials, see Provide Installation Credentials.
