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.
In this example, we are resetting a new DES-MK master key.
CSFDKE50 -------------- ICSF - Master Key Entry ---------
COMMAND ===>
AES new master key register : EMPTY
DES new master key register : PART FULL
ECC new master key register : EMPTY
RSA new master key register : EMPTY
Specify information below
Key Type ===> DES-MK (AES-MK, DES-MK, ECC-MK, RSA-MK)
Part ===> RESET_ (RESET, FIRST, MIDDLE, FINAL)
Checksum ===> 40
Key Value ===> 51ED9CFA90716CFB
===> 58403BFA02BD13E8
===> 0000000000000000 (AES-MK, ECC-MK and RSA-MK only)
===> 0000000000000000 (AES-MK, ECC-MK only)
Press ENTER to process.
Press END to exit to the previous menu.
The Restart Key Entry Process panel appears. See Figure 2. This panel confirms your request to restart the key entry process.
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
The restart request automatically empties the master key register.
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 3. This indicates that the register has been cleared.
