LDC004
Explanation: (soft abend) This is an HCPLDCEF
process error; guest page zero cannot be acquired. A
call to HCPPZERO to acquire a specified virtual
machine’s guest page zero was not successful.
User Response: Determine the virtual machine
executing at this time and why the virtual machine’s
guest page zero could not be fetched.
LDD003
Explanation: (soft abend) This is an HCPLSMUU
output error; invalid return code from HCPLSMUU.
During logical device present processing, HCPLSMUU
returned an incorrect value in R15.
User Response: Examine the value in R15 (through
the trace table) and determine how HCPLSMUU arrived
at that value.
LDD007
Explanation: (soft abend) This is an HCPLSMUS
output error. During logical device status processing,
HCPLSMUS returned an incorrect value in R15.
User Response: Examine the value in R15 (using the
trace table) and determine how HCPLSMUS arrived at
that value.
LDD008
Explanation: (soft abend) This is an LDDBK
information error. Waiting for Read-Buffer and waiting
for Read-modified are both set. During logical device
present processing, the logical device was waiting for
both a read-buffer and a read-modified (LDDWTNG).
Present processing proceeded with read-buffer
processing if the present was for a read-buffer; present
processing proceeded with read-modified processing if
the present was for a read-modified. At completion of
this logical device present processing, the logical device
is not waiting for a read (buffer or modified).
User Response: Determine if a read-buffer or a
read-modified was attempted and if it was successful
(data was moved). Determine how both waiting for
read-buffer and waiting for read-modified were set.
Check for previous presents and/or reads to this device
which may have failed.
LDE002
Explanation: (soft abend) The system will soft abend
if HCPLSMUS returns with a return code that is not 0,
as this is the only valid return code.
User Response: Examine the return code given by
HCPLSMUS and determine why it issued that return
code.
LDE017
Explanation: The deferred execution counter,
VMDDFRWK in the VMDBK, was about to become
negative.
User Response: Examine the CP trace table and
storage dump to see why the VMDBK pointed to by R11
has a zero value for the VMDDFRWK field.
See the description of DFR017 for possible reasons
why this may have occurred.
LDF001
Explanation: Issued during a Diagnose x’2C0’ if the
requested file size exceeds the caller-specified buffer
size.
User Response: Contact your IBM support personnel.
LFC001
Explanation: HCPLFCRL is called to remove a
Multi-Path Lock Facility (MPLF) RPQ simulation
configuration. The guest is the last user attached to the
configuration. The configuration name must be removed
from the configuration name table that contains a list of
active configurations. However, the configuration name
cannot be found in the table.
User Response: This is most likely a software error.
Possible causes are:
v The configuration name table was corrupted.
v Another process removed the configuration name
without properly locking access to the table.
LFP001
LDC004 LFP001
Explanation: Issued by the HCPLFP module. This
module is distributed as object code only. Therefore, no
source program materials are available.
HCPLFPSF found a zero VMDBK address when
attempting to identify a connected Multi-Path Lock
Facility (MPLF) RPQ user.
User Response: Refer to the z/VM: Diagnosis Guide
for information on gathering the documentation you
need to assist IBM in diagnosing the problem, then
contact your IBM support personnel.
This is most likely a software error. Possible causes are:
v The subsystem connect table was corrupted.
v Another process removed the user from the
configuration without properly locking access to the
user’s configuration block.
