Before you start configuring the server complexes, there are a
number of tasks you need to perform to ensure that the z/VM networking
properties are set up correctly.
Setting connection properties for Linux guest systems
Before you can set the network interfaces for server complexes,
you must set up the connection properties for guest LANs, OSAs, or VSWITCHes
in the z/VM. These will be used to route the Linux guest systems.
Reserving IP addresses
You can reserve a specific IP address by adding it to the Occupied
IP Addresses list in the Connection Properties window. This prevents others
from using that particular IP address.
Scanning for occupied IPs
You can run a scan for the occupied IPs of existing connections
in the z/VM. This action updates the list of IP addresses that are already
being used by managed systems known to the IBM Director server.
Saving the current networking properties
If you change the networking properties of connections in the z/VM,
you must save these changes. This is not done automatically when you click OK in
the Connection Properties window.
Resetting the connection properties
It is impossible to clear all the properties of a selected connection
by deleting the fields in the Connection Properties window. To clear these
properties, you need to reset the connection.
Refreshing networking properties from the z/VM
If you made changes to the networking properties in the Connection
Properties window, you will need to refresh the list in the z/VM
Networking Properties window so the correct details are displayed. You also
need to do this the first time you open the z/VM Networking Properties window.
