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 about 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 X'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 X'0' – X'F'. See PR/SM Planning Guide.

03
More CPUs were defined for the partition than the installed level of z/OS supports. The system encountered a CPU address that exceeds the maximum allowed by this level of z/OS.

System programmer response: Reduce the number of logical CPUs defined for the partition in the LPAR image profile (see PR/SM Planning Guide) to a number less than or equal to the number of CPUs supported by the installed level of z/OS (see ECVT_MAX_HIGHESTCPUID in z/OS MVS Data Areas Volume 1 (ABE - IAR)).

04
The system contained the following mutually exclusive facilities:
  • An Integrated Facility for Applications (IFA)
  • 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.

06
Multithreading (MT) activation defined a CPU address that exceeds the maximum allowed by this level of z/OS.

System action: The system enters a non-restartable wait state.

Operator response: Contact the system programmer.

System programmer response: Reduce the number of logical CPUs defined for the partition in the LPAR image profile (see PR/SM Planning Guide) or deactivate MT (see the LOADxx member of parmlib in z/OS MVS Initialization and Tuning Reference) to a number less than or equal to the number of CPUs supported by the installed level of z/OS (see ECVT_MAX_HIGHESTCPUID in z/OS MVS Data Areas Volume 1 (ABE - IAR)).

07
MT activation encountered an unexpected error.

System action: The system enters a non-restartable wait state.

Operator response: Contact the system programmer.

System programmer response: Search problem reporting databases for a fix for the problem. If no fix exists, contact the IBM® Support Center.

08
The system was IPLed with an unsupported CPU or CORE type.

System Action: The system enters a non-restartable wait state.

Operator Response: Notify the system programmer.

System Programmer Response: Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM Support Center.
