Summary: IBM® Systems Director is a platform management solution that is used to manage physical and virtual systems in a multisystem environment. It supports various virtualization technologies and multiple operating systems across IBM and non-IBM platforms. IBM Systems Director VMControl™ is an advanced manager of IBM Systems Director, a free-to-own set of platform management tools. This tutorial is part of a series on VMControl resource lifecycle management. This tutorial explains about server system pool lifecycle using the VMControl Representational State Transfer (REST) application programming interfaces (APIs).

About this series

The IBM Systems Director VMControl advanced manager simplifies the management of virtual environments across multiple virtualization technologies and hardware platforms. VMControl is a leading multi-platform virtualization management solution that is included with IBM Systems Director Editions. VMControl has the support for three types of interfaces (GUI, CLI and REST APIs). This series talks about the VMControl resources lifecycle through REST.

This series has the following lifecycles:

Virtual server lifecycle management through the VMControl REST APIs: This covers the lifecycle (create, view, edit, and delete) management of a virtual server. It highlights the capabilities of VMControl Express Edition, the free portion of VMControl.
Virtual appliance lifecycle management through the VMControl REST APIs: This covers the lifecycle management of a virtual appliance. A virtual appliance is an operating system image and metadata that is capable of being remotely installed (deployed) on a new or existing virtual server.
Image deployment through the VMControl REST APIs: This walks through a typical deploy process and the workload lifecycle management of the workload created using this deploy process.
Server system pool lifecycle management through the VMControl REST APIs: This covers the lifecycle management of a server system pool and its virtual server relocation capabilities. A server system pool is a grouping of similar physical servers (hosts) – VMControl version of a cloud. VMControl chooses which host to deploy to and allows for relocation of virtual servers within the server system pool.

This series will help all the VMControl users to understand the VMControl functionality through REST. It will also help to understand the detailed flow of the resource lifecycle.

About this tutorial

This tutorial illustrates the life cycle of server system pool resource using the VMControl REST APIs. The lifecycle of a server system pool has the following major functions:

Create a server system pool
List server system pool and its members
Modify a server system pool (modify properties and add/remove host)
Relocate a virtual server
Delete a server system pool

Figure 1 explains the server system pool lifecycle in detail with the sequence of different REST requests.

Objectives

The main objective of this tutorial is to help users understand the server system pool lifecycle using the VMControl REST APIs. This tutorial describes the complete lifecycle with the purview of using it with IBM System Director VMControl. Users with the basic knowledge on server system pool and IBM Systems Director VMControl can walk through the tutorial easily.

Prerequisites

You should have IBM Systems Director V6.x.x installed on your system before proceeding. This tutorial assumes that you are familiar with using IBM Systems Director. It also assumes that you have a reasonable understanding of JavaScript Object Notation (JSON) and how to make HTTP GET, POST, PUT, and DELETE calls using your favorite HTTP client.

System requirements

You should have the following components on your system.
