Previous: Automated deployment of Hybrid Cloud NetApp Storage.

The sequence of steps are as follows:

  1. Define the workflow.

    • Create a short, user-friendly name for the workflow, such as Disaster Recovery Workflow.

  2. Define the workflow input. The inputs we take for this workflow include the following:

    • Volume options (volume name, mount path)

    • Volume capacity

    • Data center associated with the new datastore

    • Cluster on which the datastore is hosted

    • Name for the new datastore to create in vCenter

    • Type and version of the new datastore

    • Name of the Terraform organization

    • Terraform workspace

    • Description of the Terraform workspace

    • Variables (sensitive and nonsensitive) required to execute Terraform configuration

    • Reason for starting the plan

  3. Add the workflow tasks.

    The tasks related to operations in FlexPod include the following:

    • Create volume in FlexPod.

    • Add storage export policy to the created volume.

    • Map the newly created volume to a datastore in VMware vCenter.

      The tasks related to creating Cloud Volumes ONTAP cluster:

    • Add Terraform workspace

    • Add Terraform variables

    • Add Terraform sensitive variables

    • Start new Terraform plan

    • Confirm Terraform run
