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.
Complete the following
steps to edit the network
configuration domain:
- If it is not started already, start the Server Complexes
task for the z/VM system you want to work with.
- Select the server complex for which you want to define the network
interfaces.
- Click Action → Edit Properties to open the Server
Complex Properties window and click the Network tab to display the
Network page.
- Choose whether the configuration target is the whole server complex
or a specific tier.
- If you chose the Specific tier radio button, choose the
target tier.
- 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.
- (Optional) Repeat the process for the other network interfaces.
- 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.
- 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.
- In the Guest Selection window, choose the Linux
guest systems on which to apply the reconfiguration, and click Yes.
- 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.
