/mcpDescription Installation Method Note This installation method is applicable only for VMware vSphere ESXi. Allows you to perform fully automated installation or direct migration of either a single node or an entire cluster, using the VMware OVF Tool. To install or direct migrate a cluster, follow the procedures at Automated Installation using vApp properties and VMware OVF Tool, on page 72: • Use the VMware OVF Tool to create a skip-install OVA for each cluster node (with OVA parameters filled in, instead of using Answer File Generator). • Deploy all cluster nodes skip-installed OVAs simultaneously. • Installation continues like Touchless Install of a Single Node or Cluster or Fresh Install with Data Import. It is best to use this method with skip-install OVAs, as that provides the shortest duration and highest level of automation. Use this method when you require a programmatic install or direct migration method on top of any of the factors that drive consideration of Touchless Install of Cluster or Fresh Install with Data Import.
