If you realize that you made an error when entering a key part, you can restart the process of entering the new master key. For example, if the verification pattern or the hash pattern that was calculated does not match the one that you calculated, you may want to restart the process. Restarting the key entry process clears the new master key register, which erases all the new master key parts you entered previously.

To restart the key entry process, follow these steps:

1. On the Master Key Entry panel, enter the master key type in the Key Type field.

   In this example, we are resetting a new DES-MK master key.

2. Enter RESET in the Part field.

     Press ENTER to process.
     Press END   to exit to the previous menu.

3. Press ENTER.

   The Restart Key Entry Process panel appears. See Figure 94. This panel confirms your request to restart the key entry process.

   Figure 94. Confirm Restart Request Panel

    CSFDKE80 -------------- ICSF - Restart Key Entry Process -------------
    COMMAND ===>
   
    ARE YOU SURE YOU WISH TO RESTART THE KEY ENTRY PROCESS?
   
   
      Restarting the process will clear the DES-MK master key register.
   
   
      
   
   
   
    Press ENTER to confirm restart request
    Press END   to cancel restart request
    

4. If you want to restart the key entry process, press ENTER.

   The restart request automatically empties the master key register.

5. If you do not want to restart, press END.

   When you make a choice, you return to the Master Key Entry panel. If you selected to continue with the restart process, the new master key register status field is reset to EMPTY, as shown in Figure 95. This indicates that the register has been cleared.

6. Either begin the key entry process again or press END to return to the ICSF primary menu panel.
