/mcpStep 4 Click Images in the left pane, then select Add Image. Step 5 On the Add Images page, you can either choose the Image File and click + Add File to select the locally downloaded file to upload to the Nutanix cluster, or select the URL radio button to upload the bootable .iso image from a remote server by providing the NFS path in the Image URL field. Step 6 Click + Add URL and provide the authentication credentials to connect to the remote server. Step 7 Click Next and save the changes. Step 8 Check the status of the image upload on the Tasks page to confirm the successful upload of the .iso image to the Nutanix cluster. For example, a URL is the following: nfs://<Host IP>/<path>/Bootable_UCSInstall_UCOS_15.0.1.xxxxx-xx.sha512.iso. Power On the Virtual Machine After you have mounted your ISO image to your application VMs, run the touchless installation process. You can install all nodes simultaneously. Automated Installation using vApp properties and VMware OVF Tool This feature uses a skip-install Open Virtual Archive (OVA) file containing an application that is installed up to the “skip” configuration point, where the application is ready to accept the configuration and complete installation. The VMware OVF Tool is used to deploy and inject the Unified CM and IM and Presence Service configuration parameters into the virtual machines using skip-install OVA and vApp properties without using Answer File Generator or vFloppy images. Deployment vApp options are available for virtual machines that are deployed from VMware Open Virtualization Format Tool (OVF) Tool to the desktop or to the web server (Application available only on vcenter). For a virtual machine with vApp options enabled, the vApp options are preserved when you export the virtual machine as an OVF template. Without manual intervention from the administrators, you just need the skip-install OVA image to install the entire Unified CM clusters. Using the vApp parameters, you simply need to define a template and set the values of vApp Properties and inject all the details during deployment of the skip-install OVA using the VMware OVF Tool that results in automated installation. Fresh Install and Fresh Install with Data Import is supported using this method. You can deploy this installation in two ways: • Manual Installation Using vApp Options—Deploy the skip-install OVA on each node in the cluster manually by logging into the respective VMware Embedded Host Client or vCenter Server, where the Unified CM server configurations can be entered. • Touchless Installation Using VM Builder and VMware OVF Tools—Run the VM Builder tool (which is a VMware wrapper tool that is provided as part of the platform skip-install-ova rpm/tar) by passing the Unified CM configuration parameters, skip-install OVA, and VMware Embedded Host Client or vCenter Server details of each node in the cluster, which would perform the complete cluster installation without manual intervention.
