Setting network interfaces for a server complex

By setting the network properties, you can define up to four network interfaces to be configured on a Linux guest system contained in the server complex.

You can set each interface for configuration on an existing z/VM guest LAN or VSWITCH, or for direct attachment on an OSA card.
註: Before you can set the networking properties for server complexes, you must set up the connection properties that connections will use for routing the Linux guest systems. (See Setting connection properties for Linux guest systems)

Complete the following steps to edit the network configuration domain:

  1. If it is not started already, start the Server Complexes task for the z/VM system you want to work with.
  2. Select the server complex for which you want to define the network interfaces.
  3. Click ActionEdit Properties to open the Server Complex Properties window and click the Network tab to display the Network page.
  4. Choose whether the configuration target is the whole server complex or a specific tier.
  5. If you chose the Specific tier radio button, choose the target tier.
  6. In the Interface # 0 field, choose from the list of connections for which routing properties were entered. After you define an interface, the expected Linux interface name (e.g., eth0, hsi0) appears to the right of the selection list.
    • A guest LAN element is shown as LAN lan-name
    • A VSWITCH element is shown as VSWITCH vswitch-name
    • An OSA element is shown as OSA chpid min-rdev max-rdev where chpid is the channel path ID, and min-rdev and max-rdev are the lowest and highest real device numbers of the OSA.
  7. (Optional) Repeat the process for the other network interfaces.
  8. In the Default gateway field, choose the default gateway for configuring on the Linux guest system. The list includes the default gateways of the selected connections in the Interface# fields. You can also type in a different default gateway, which is not included in the list.
  9. Click OK to apply the modified settings to the Linux guest systems currently in the server complex. If you modified settings in any of the other domains (except for the Scripts domain), these are also applied to the Linux guest systems in the server complex.
  10. In the Guest Selection window, choose the Linux guest systems on which to apply the reconfiguration, and click Yes.
  11. Before applying the modified properties, the Server Complexes task runs a consistency check against the old properties. The Progress Indication window shows the progress of the action. If there is an inconsistency, you are given a choice whether to proceed or stop. Stopping saves the new properties but doesn't apply the configuration. After the operation is completed, click Close to close the Progress Indication window.
註: At any time, with or without changing the property values, you can open this page and click the Apply button to directly apply the properties of this domain to Linux guest systems in the server complex. For more information, see Directly applying server complex properties in a single domain.
