HCP9020W HCP9025W
HCP9020W SYSTEM LOAD FAILURE; PROGRAM
CHECK
Explanation: A program check occurred during the
IPL process. The module code in the message identifier
indicates the module executing when the program check
occurred.
System Action: The system enters a disabled wait
state (wait-state code = 9020).
If using the Stand-Alone Program Loader, all registers
will contain the values held at the time the wait state
was entered.
Operator Response: Take a stand-alone dump and
contact your system support personnel. Attempt a
FORCE start. If that fails, attempt a COLD start. If the
failure continues, contact your IBM Support Center
personnel for assistance.
HCP9021W SYSTEM LOAD FAILURE; MACHINE
CHECK
Explanation: A machine check occurred during the
IPL process. The module code in the message identifier
indicates the module executing when the machine
check occurred.
System Action: The system enters a disabled wait
state (wait-state code = 9021).
If using the Stand-Alone Program Loader, all registers
will contain the values held at the time the wait state
was entered.
Operator Response: IPL the system with a WARM
start. If that fails, attempt a FORCE start. If that is
unsuccessful, attempt a COLD start. If the failure
continues, contact your IBM Support Center personnel
for hardware support.
HCP9022W SYSTEM LOAD FAILURE; FATAL I/O
ERROR
Explanation: An irrecoverable input/output error
occurred on the system residence volume during the
IPL process. The module code in the message identifier
will show the module where the fatal I/O error occurred.
System Action: The system enters a disabled wait
state (wait-state code = 9022). The codes for this
message are as follows:
Code Explanation
R0 Contains the address of the device in error
R1–R3 Contains the extended status CSW in the
interrupt response block
R4–R11
Contains up to 32 bytes of sense information
R12 Base register if using the Stand-Alone Program
Loader
456 z/VM: System Messages and Codes — CP
R13 Work page address if using the Stand-Alone
Program Loader
R14–R15
Contains BBCCHHR if the device is a
CKD/ECKD or zero if using the Stand-Alone
Program Loader
R14 Contains the hexadecimal block number if the
device is an FBA or zero if using the
Stand-Alone Program Loader.
User Response: None.
HCP9023W SYSTEM TERMINATION FAILURE;
MULTIPLE INCIDENTS
Explanation: Multiple system incidents have occurred
on the same processor during the termination process.
System Action: The system enters a wait state
(wait-state code = 9023).
Operator Response: Use the IPL NOCLEAR
command to retry the checkpoint function. If the failure
persists, contact your IBM support center.
HCP9024W CONSOLE I/O ERROR
Explanation: An irrecoverable I/O error occurred while
the system was trying to write a message to the
operator’s console. This is often caused on a
second-level system by a console defined as something
other than a 3270.
System Action: The system enters a wait state
(wait-state code = 9024). No message is displayed.
Operator Response: Disable the console and attempt
to IPL to get an alternate console. If you are running
second level, make sure that your console is defined as
a 3270.
HCP9025W SYSTEM TERMINATION COMPLETE,
ENTERING WAIT STATE
Explanation: The system termination process has
completed. The system will not restart for one of the
following reasons:
1. An error was detected in the error recovery
hardware or software.
2. A machine check shows damage to a storage page
that the CP nucleus occupies.
3. There is severe I/O subsystem damage.
4. A hard abend occurred when dump conditions were
set to NOIPL.
5. The system has been successfully shut down and
has not been IPLed again. (This wait state will occur
if a system restart is attempted after the shutdown
command completed.)
6. An attempt was made to IPL an alias Parallel
Access Volume. An IIO002 abend will have occurred
