In Rhino VM automation, you can manage the life cycle of the VMs by using the SIMPL server. For example, you can upgrade or delete a VM.

Note Rhino VM automation currently doesn’t support the healing and the scaling in/out life-cycle management operations.

VM upgrade and rollback

The upgrade and rollback processes are similar. When you upgrade VMs, you replace them with a later version of the VMs. Whereas when you roll back VMs, you replace them with an earlier version of the VMs.

During the upgrade or rollback process, the SIMPL server replaces the VMs on the virtualization platform one by one. For each VM, the server performs the following tasks:

  1. Instructs the VM to permanently shut down services and leave the network.

  2. Waits for the VM to report that the above process is complete.

  3. Removes the VM.

  4. Creates a new VM instance.

  5. Waits for the VM to report its readiness status.

For detailed instructions on VM upgrading or rolling back, see the rolling upgrade information in the Custom VM Install Guide.

VM removal

When you no longer need a VM group or the entire deployment of the VMs, you can use the SIMPL server to delete the group of VMs or all the VMs deployed.

For detailed instructions on deleting VMs, see the SIMPL product documentation listed in the Related information section.
