If you develop a problem with the current console, depending on
the type of problem, you might be able to recover access to the system by
changing the console type.
Note: The following information assumes that hardware to support a new console
type is available in the correct location or can be tagged without the need
to add or move hardware. Systems with an HMC require at least one tag change
prior to selecting a new console type. The tag change, unless performed using
the alternate method (commonly referred to as dynamic tagging), requires a
shutdown and activation to reflect a change in the partition profile. This
same restriction also applies when you are ready to return to the original
console type.
Before you start, observe the following:
- There are several console
service functions (65+21) that might be needed to recover or resolve
an Operations Console problem. These might work depending on the problem,
connectivity used for the current console, the target console type, and the
current state of the system.
- If you are unsure of any function or recovery action, contact your authorized
service provider for assistance.
Use one of the following methods to change the console type:
- If you are using a PC connected to a LAN for the console and have another
PC set up to be the console, you might be able to use the other PC for the
console until the problem with the first console is fixed.
- Use SST from another workstation.
- Use the console service functions (65+21) to
change or reset the console.
- Use the appropriate native macro from another workstation. Any hardware
allocations or configurations must be accomplished before connecting with
another connectivity. For example, you can use the alternative method for
tagging a different console to save an IPL instead of deactivating and activating
the partition to enable the change with just the partition profile. Some tasks
might require one or more IPLs to get the system into a state where you can
use the new console.

and terminals.
