To create your own OVF template for adding new worker instances, you will need:
- An existing system that has either one or three master instances.
For information on setting up a system, see Installing HCI.
- An HCI OVF template. This can be either:
- The Hitachi Vantara-provided OVF template contained in the Hitachi Content Intelligence-OVF-EXAMPLE-<version-number>.tgz file.
- An HCI OVF template that you created yourself. For information, see Creating a production HCI OVF template.
Additionally, to let a new worker instance automatically join an existing system, you need to configure DHCP in your environment to automatically assign IP addresses to your newly-created instances.
Note: Your system needs the IP address of each instance to stay the same. Though an instance's IP address can initially be set dynamically, you need to configure that IP address to remain static. For more information, see Set a static IP for the new instance.
The following are the steps needed to create your own OVF template:
- Create a list of the master instances
- Deploy a new virtual machine for each instance
- Modify the virtual machine to suit your environment
- Edit the cluster.config file
- Enable the HCI.service file
- Configure NTP
- Export the OVF template
- Use the OVF template to add a new instance
- Set a static IP for the new instance
