De-registering an operating system instance

When you de-register an operating system instance, you remove all knowledge of it from z/VM Center.

De-registering does not de-install the operating system nor free the disks where the operating system instance and related data reside for redeployment. To free the resources you must delete the z/VM virtual server. You need to de-register an operating system instance before you can create or register a new operating system instance.

Complete these steps to de-register an operating system instance:

  1. If it is not started already, start the Virtual Server Deployment task for the z/VM System you want to work with.
  2. In the z/VM System resource tree, expand the z/VM Virtual Servers node to display a list of z/VM virtual servers.
  3. Expand the node for the z/VM virtual server with the operating system instance that you want to de-register; then expand the Operating Systems node below it.
  4. Select and right-click the operating system instance you want to de-register; then click De-Register Operating System. You are prompted to confirm that you want to de-register the operating system instance.
