Error messages

The Set Master Key (SETMSTK) command installs a new host master key on your system.

If an old master key exists, the values in the cross-domain key table are reencrypted under the new host master key value. You supply the values for two key parts, which are exclusive-ORed together to produce the new host master key. The new host master key must have odd parity in every byte.

To run this command, the system must be in a restricted state. (Enter the End System (ENDSYS) command to obtain a restricted state.) After installing the master key, return your system to a normal state by restarting your subsystems.

There are no parameters for this command.
