The Change Master Key (CHGMSTK) command displays the Change Master Key prompt. Using this prompt, you can change the host master key on the system. 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.

The values in the cross-domain key table are reencrypted under the new host master key value.

To use this command, the system must be in a restricted state; enter the End System (ENDSYS) command to get to a restricted state. Once the master key is installed, you can return your system to a normal state by restarting your subsystems.

There are no parameters for this command.
