Scenario: Using system profiles

Situation

You are the system administrator for a business recovery service center with IBM^® eServer™ hardware. You use IBM eServer hardware primarily to test disaster-recovery strategies for your clients. Each of your clients has a different system configuration. This means that, each time a client comes in, you must change the system configuration of your managed system.

You decide to create and use system profiles to change the system configuration of your managed system. First, on each logical partition on your server, you create a partition profile for each client that uses the logical partition. Then, you create a system profile for each client. Each system profile contains the partition profiles that you want to activate for the client. When a client returns to the business recovery service center, you can reconfigure the managed system for that client simply by activating the system profile for that client.

You have just finished testing for Client 1. You must now reconfigure the managed system for Client 2, who comes in tomorrow.

Objectives

The objective of this scenario is to change the configuration of your managed system by using system profiles.

Details

Your managed system has eight processors and 12 GB of memory. You have created two system profiles on this managed system. Each system profile divides the resources of the managed system between two or three logical partitions.

Prerequisites and assumptions

This scenario assumes that the following prerequisite steps have been completed prior to beginning the configuration steps:

1. The Hardware Management Console (HMC) was set up.
   • The HMC was cabled.
   • You completed the planning process and you understand how you want to configure your HMC.
   • You used the Guided Setup wizard or the HMC configuration checklist to set up the HMC.
2. You understand the concepts for partitioning the server.
3. You completed the tasks recommended for logical partition planning.
4. You moved and assigned the physical hardware according to the LPAR Validation Tool (LVT) output.
5. You logged in to the HMC with one of the following user roles:
   • Super administrator
   • Service representative
   • Product engineer
6. You created the logical partitions, partition profiles, and system profiles described.
7. You activated the system profile for Client 1.

The following table lists the system profile that is currently active on the managed system.

Configuration steps

After shutting down the logical partitions, you can activate the system profile for Client 2. To do this, complete the following steps on your HMC:

1. In the navigation area, open Server and Partition.
2. Select Server Management.
3. In the contents area, open the server.
4. Open System Profiles.
5. Right-click the Client 2 system profile and select Activate.
6. Select the activation settings you want to use and click Continue.

After activating the system profile, the managed system is configured according to the needs of Client 2. The following table lists the system profile that is currently active on the managed system.
