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:
- If it is not started already, start the Virtual Server
Deployment task for the z/VM System you want to work with.
- In the z/VM System resource tree, expand the z/VM Virtual Servers
node to display a list of z/VM virtual servers.
- 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.
- 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.
