P11 master key parts are loaded using smart cards only. You may
enter up to 20 master keys parts.
Note: - If your ICSF instance (single system or LPAR image) is
using multiple EP11 coprocessors, they must have the same master key.
Therefore, the new master key registers in all EP11 coprocessors must
contain the same value.
- If you are reentering master keys after they have been cleared,
use the same master key part values as when you originally entered
the keys.
