Procedure

  1. Invoke the Network Topology Tool to display the TCP/IP address of Interface eth0.
    1. From the navigation area, click HMC Management.
    2. In the right work area, go to the Operations section and click View Network Topology.
    3. Wait several minutes for the tool to gather and present the results.

      A window appears with the current network topology (port connections) listed at the top and the saved network topology listed at the bottom. See Figure 1.

    4. In the area labeled Current Topology, click an Interface eth0 LPAR. The details of that node are displayed in the right pane. Note the IP address. In Figure 1 it is 172.16.0.1, the default address range in Table 2.

  2. Determine the address range for the LPAR IP address that you recorded in step 1. For LIC bundles at or below 64.xx.xx.xx (Release 4), use Table 1.For LIC bundles at or above 65.xx.xx.xx (Release 5), use Table 2.
    Table 1. Address ranges of the storage facility private network (LIC bundles 64.xx.xx.xx and prior)
