Recovery actions for a locked keyboard

You may find that you cannot enter commands through a console that otherwise appears normal.

Note: Inhibited input, with or without keyboard locking, can also occur for the following system programming problems. See System programming problems.

The system enters a wait state.
The system is in a disabled loop.
A problem occurs in message processing in the operating system.

Look for software problems first, based on messages and logrec data set error records. Many software problems can inhibit console input.
If no software problems are found, try to restore the screen by performing a cancel action, which may be pressing the PA2 key.
Contact hardware support to fix the error in the failed console.
