CLF001
Explanation: (Hard abend) R0 at entry to HCPCLFGT
was less than 1.
User Response: Investigate why the caller to
HCPCLF attempted to release 0 pages.
CLG001
Explanation: (Hard abend) An impossible internal
condition occurred. An error was returned from
HCPCFDAD. A request for HCPCFDAD to add an
external symbol to the CP external symbol table was
rejected, even though validation by HCPCLG indicated
that the add request should succeed. The return code
from HCPPTVAF is in register 15.
User Response: Use the return code in register 15 to
determine why HCPCFDAD rejected the request.
CLG002
Explanation: (Hard abend) Paging error. Error return
from HCPCFDAD. Request for HCPCFDAD to add an
external symbol to the CP external symbol table failed
due to a system paging error.
User Response: Contact IBM support personnel.
CLH001
Explanation: A problem was detected in an ESDBK
during CPXUNLOAD processing. The fields in this
ESDBK do not match what is expected. It should
represent a symbol that was added to the symbol table
when the CPXLOAD occurred. This abend indicates that
either the expected ICLBK pointer is zero, or there is a
problem deleting this external symbol from the symbol
table.
User Response: R14 contains the address within the
module where the problem is detected. Refer to the
z/VM: Diagnosis Guide to determine what data you will
need to provide IBM to assist you with diagnosing this
problem. Then contact your IBM support personnel.
CLH002
Explanation: A paging error occurred removing
external symbols from the external symbol map.
User Response: Refer to the z/VM: Diagnosis Guide
to determine what data you will need to provide IBM to
assist you with diagnosing this problem. Then contact
your IBM support personnel.
CLH003
Explanation: Interference occurred updating
ICLCPEBK. The ICLBK has information about external
symbols that reside in dynamically loaded modules.
Because you do not want to unload anything currently
in use, CPXUNLOAD processing appends one CPEBK
to each ICLBK in turn to wait for its usage count to
reach zero. This abend indicates that some other
process attempted to change ICLCPEBK when you
attempted to save the address of the CPEBK there.
This should never occur.
User Response: Refer to the z/VM: Diagnosis Guide
to determine what data you will need to provide IBM to
assist you with diagnosing this problem. Then contact
your IBM support personnel.
CLK002
Explanation: (soft abend) One of the following
occurred:
v One or more processors failed to process time-of-day
(TOD) clock synchronization during a TOD clock
synchronization check, which is an external interrupt.
v A processor being varied offline as a consequence of
such a failure failed to deconfigure, and as a result all
other processors except the master are varied offline.
v CP could not synchronize the TOD clocks because
you did not press the TOD enable set key. All
processors except the master are varied offline.
User Response: Message 9154E identifies the
processors varied offline. Determine if the processors
have a hardware problem. If so, contact your IBM
support personnel to diagnose and correct the hardware
problem.
CLK003
Explanation: A processor was handling a time-of-Day
(TOD) clock synchronization check, which is an external
interrupt. The TOD clock on this processor was not set.
The software will initiate a re-IPL of the system.
User Response: Resetting the processing units, which
occurs during the system IPL, may clear the TOD clock
error condition. If this does not correct the condition,
examine the trace table within the dump. The problem
could be in a hardware malfunction of the TOD clocks
of the system. Contact your IBM support personnel.
CNF001
CLF001 CNF001
Explanation: (soft abend) While processing a
DIAGNOSE code x’08’ instruction that requested a write
to buffer, CP received a request to write to a page that
is currently a read-only page. CP writes no data to the
guest’s storage.
User Response: Examine the trace table to determine
why the page was made read-only (for instance, a
read-only saved segment was loaded at the page that
contains the specified address). R1 contains the
address.
