Verify your system is ready for a backup console
Recovering from the loss of a console depends on many factors, some of which include the model, the hardware resources available, the previous console type, and the intended console type.
Recovery might consist of repairing the currently failed console or temporarily replacing it with another console type. Most changes of a console type can be performed without the need for an initial program load (IPL), but there might be circumstances in which an IPL is necessary. Before you use the console service functions (65+21), verify the following:
- For systems that are not managed by an HMC, verify that the console hardware is installed and available.
- For systems managed by an HMC, verify that the appropriate console resources are tagged in the partition profile.
If you plan to use a local console on a network (for example, a LAN) as a backup for another console type, verify that a network adapter, or the Host Ethernet Adapter logical port, is available for console use. You can still configure the service tool server on an adapter. Then if you need the LAN console, you can just connect the Operation Console to the IP that is configured.
