ICT1027 SYSTEM MASTER KEY PREVIOUSLY SET; INVALID KEY GENERATOR REQUEST

Explanation
An attempt was made to use the SETM function of
the key generator utility program to set host master key, but the
host master key has already been set. Any change to it must be requested
using the CHGM function of the utility program.

System action
Key generator utility processing ends.

Programmer response
If you want to change the host master key
and secondary key-encrypting keys, rerun the key generator utility
program specifying CHGM on the EXEC statement. If you want to change
secondary key-encrypting keys only, rerun the utility program specifying
CHGK on the EXEC statement.
