Description Installation Method Note This installation method is applicable for VMware vSphere ESXi, Nutanix AHV, and Cisco NFVIS-for-UC. A partially automated installation of one node or installation of clusterwide install of multiple nodes of Unified Communications Manager and IM and Presence Server. Use this method to get basic automation for one node, where you can fill out all the information initially, start the Install Wizard with that information, and complete the rest of the installation automatically using the Answer File. For clusterwide installations, use this method to generate pre-created Answer Files, that occurs in one seamless process with minimal intervention. To install a single node or a cluster using this method, follow the Touchless Installation steps for the hypervisor selected: 1. Create an Answer File for each node in the cluster using the Unified Communications Answer File Generator. 2. Place all those Answer Files in well-known locations. See Generate Answer Files for Touchless Install, on page 61. 3. Power on the node or all the cluster nodes simultaneously. In this method, no interaction with the native Install Wizard is required. The nodes will communicate with each other and each node will read its Answer File for instructions. You can use this method with any of the software media options available for Attended Install. Use this method to: • Get more automation—Unattended Install of the entire cluster + zero interaction with the native Install Wizard. • Faster installation—Cluster nodes undergo installation in parallel. This is especially useful if you have a large cluster with many nodes to install.
