07C

Explanation
During system initialization an error was detected
in the system configuration. The error needs to be corrected before
the system will properly initialize. A reason code in the
wait PSW explains the error: Code
Explanation
01
 A system was IPLed in a partition with a non-zero logical channel
subsystem identifier (CSSID).  The level of z/OS® installed on this system does not support
non-zero CSSIDs. System Action: Message IEA004W accompanies
the wait state.
System Programmer Response: Either IPL
the z/OS system in a logical
partition with a CSSID of 0 or modify your I/O configuration to define
this partition in CSS 0.  See z/OS HCD Planning or z/OS HCD User's Guide for
information on how to associate a logical partition with a logical
channel subsystem.

02
 A system  was IPLed in a partition with an logical partition
identifier greater than hex F.   The level of z/OS installed on this system does not support
logical partition identifiers greater than X'F'. System
Action:  Message IEA006W accompanies the wait state.
System
Programmer Response: Change the LPAR identifier assigned to the
partition in the LPAR image profile to a number in the range of X'0–F'.
 See PR/SM™ Planning Guide.

03
 More CPUs were defined for the partition than the level of z/OS installed supports. The system
encountered a CPU address space that is greater than the maximum allowed
by this level of z/OS. System
Programmer Response: Change the number of logical CPUs defined
for the partition in the LPAR image profile to a number less than
or equal to the number of CPUs supported by the current installed
level of z/OS.  See PR/SM Planning Guide.

04
The system contained the following mutually exclusive facilities:an Integrated Facility for Applications (IFA) ,and
a CPU with the Integrated Cryptographic Feature.
System Action:  The system enters a non-restartable
wait state.
Operator response:  Contact the system programmer.
System
Programmer Response: Contact hardware support.
