Bringing Up a Production System in a Virtual Machine
After you start any service virtual machines that need to be started, you are ready to bring up a production system in a virtual machine.
Although there are many ways to set up the consoles, this book
assumes that you have access to the following separate consoles:
- Processor complex's system console
- z/VM primary system console
- Console for the production system's virtual machine
- Production system's system console.
In the following explanation, bringing up the production system
requires these consoles:
- Console for the production system's virtual machine.
You use this console to control the production system's virtual machine. Log on the production system's virtual machine, set up its running environment, and enter an IPL command.
- Production system's system console.
This is the system console from which you control the production system. It is dedicated to the production system's virtual machine.
- z/VM system
console.
If you need to dedicate devices to the production system's virtual machine before you bring it up, you enter the appropriate CP commands from this console.
Note:
- To eliminate a console, your installation may configure the consoles so that the console for the production system's virtual machine and the production system's system console are the same physical display. You then operate the production system in full-screen mode. See the z/VM: Virtual Machine Operation for an explanation of how to enter commands in this environment.
- For Linux® guests, you might want to automate the loading of Linux whenever its virtual machine is logged on. See z/VM: Getting Started with Linux on IBM Z for more information.
To bring up the production system, follow these steps:
- Log on the production system's virtual machine.
- Load (IPL) the production system in its virtual machine.
- Finish bringing up the production system.
- Optionally, disconnect the production system's virtual machine.
These steps are described in the sections that follow.
