5.1.4 Removing memory dynamically The following steps provide a way to remove memory from a logical partition dynamically: 1. Right-click the logical partition where you want to initiate a dynamic LPAR operation. The first window in any dynamic LPAR operation will be similar to Figure 5-12. Figure 5-12 Initial dynamic LPAR window The memory settings before the operation are: # lsattr -El mem0 goodsize 512 Amount of usable physical memory in Mbytes False size 512 Total amount of physical memory in Mbytes False 268 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
Figure 5-13 shows the tab to decrease memory. Make the required changes, as indicated in the figure. Figure 5-13 Dynamic removal of 256 MB memory 2. Click OK when done. A status window is shown (Figure 5-14). Figure 5-14 Status window Chapter 5. System management 269
