2. Select the check box AIX or Linux and enter a partition ID and partition name, as shown in Figure 3-30. Figure 3-30 Creating NIM_server partition 3. Repeat steps 4 to 15 of 3.2.1, “Defining the Virtual I/O Server partition” on page 124 with the following exceptions: a. Make a note of the Partition ID, as you will need this later. b. Use 256/512/768 MB for minimum/desired/maximum memory settings on step 6, or appropriate values for your configuration. c. Use 0.1/0.2/0.4 processing units for minimum/desired/maximum settings on step 8, or appropriate values for your configuration. d. Use 1/2/2 for minimum/desired/maximum virtual processor settings on step 9. We set the maximum to two since we use a system with two processors and the system cannot utilize more than the number of physical processors. 4. Skip step 10 by clicking Next instead of choosing to create a physical I/O component selection since we are not using physical adapters in our clients. 152 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
5. Create one virtual Ethernet adapter, as shown in 3.4.2, “Creating a Shared Ethernet Adapter” on page 149. Do not check the Access external network box. Note: We increased the maximum number of adapters to 100. Create the client and server SCSI adapters. We chose one SCSI adapter for disk and one SCSI adapter for the virtual optical device. Follow these steps to accomplish this: 1. Select the SCSI tab. You will see a window similar to Figure 3-31. Figure 3-31 Create client virtual SCSI adapter Chapter 3.
