If your panel message returns NOT SUCCESSFUL or PPINIT fails to complete, try to:

1. Delete and reallocate the CKDS
2. Delete and reallocate the PKDS
3. Go to the ICSF Coprocessor Management Panel to list the coprocessors and their status:

4. Make sure that these registers are EMPTY (for C0 and C1): DES new master key register, the current signature master key register (SMK) and the PKA key management master key register (KMMK). On a z900, you should see this:

5. If the registers are not EMPTY, go to Entering master key parts. Reset the registers that are not EMPTY. Be sure to check both C0 and C1.
6. If you have one or more PCICCs, there is no checking to be done.
7. Rerun PPINIT.
