Info

. Fill out the values for the tunable parameters. When you leave a value blank, it takes a default value. In this example, there are no Instance defaults, so all the PLM defaults, displayed on the right-hand side of the window, are used. In this example, we have changed the entitled capacity delta from 10 percent to 20 percent, so PLM will add or remove 20 percent of the current resources when performing a DR operation. We have reduced the number of notify intervals to just two; this means that after two notifications for low CPU, PLM will try to find resources to help the partition. We have reduced the CPU load maximum to 80 percent, which means that when CPU load average attains 80 percent, the agent will send a notification to the PLM server. We have also reduced the minimum entitlement per virtual processor to 0.4. Click on the OK button when you have finished and a summary of the group definition is shown (see Figure 6-11). Figure 6-11 PLM wizard group definition summary window 7. Having defined the group, we must now specify which partitions are included in the group. To do this task, click the Partitions tab in the Create Policy File window and then the Add button of the pop-up window, as shown in Figure 6-12 on page 401. 400 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
Figure 6-12 PLM wizard add managed partition window There is a pull-down menu for the group name, which is useful when you have created several groups. In the Partition name field, you type the host network name. This must be the same host name used when configuring RMC. If you used fully-qualified host names, this must fully qualified too. Attention: The Partition name field in the user interface is not for the name of the partition defined in the HMC but for the network name. Chapter 6. Partition Load Manager 401
