z/VM: System Messages and Codes Š CP - z/VM - IBM

VAT003
Explanation: (soft abend) Dynamic Address
Translation (DAT) does not exist in XC mode virtual
machines.
User Response: Examine the dump to see if
VMDPSW in the VMDBK of the failing user to see if
PSWTRAN is set incorrectly.
VCB001
Explanation: A VCB code passed to the verifiable
control block free storage manager was not valid
(detected on obtain function only).
User Response: Contact your IBM support personnel.
VCB002
Explanation: The address passed to the verifiable
control block free storage manager was not valid
(detected on release function only) because of one of
these reasons:
v The block address exceeds real machine storage
size.
v The block is not contained in a verifiable control block
free storage frame.
v The address of the block is not properly aligned.
v The block already resides on a verifiable control
block free storage available block list.
User Response: Contact your IBM support personnel.
VCB003
Explanation: Verifiable control block free storage
internal damage occurred (detected on release function
only) because of one of these reasons:
v The FRMTE was damaged; the VCB code in the
FRMTE was destroyed.
v The FRMTE should be on the SUBBK FRMTE list,
but it is not.
User Response: Contact your IBM support personnel.
VCH001
Explanation: (soft abend) A nonzero return code was
received from HCPPTTMT. An internal programming
error caused HCPVCH to pass data in the PTTBK to
HCPPTTMT. That module rejected the data as incorrect.
User Response: Examine the SNAPDATA in the soft
abend. The SNAPDATA parameter list contains the
address of the HCPPTTBK that was passed to
HCPPTTMT. It also contains the address of the DSLBK
that HCPVCH was processing when it called
HCPPTTBK. When you obtain this information, contact
your IBM support personnel.
VCR001
Explanation: HCPVCR issues this abend if the
console task chain (RDEVCON) has been corrupted
after translating a read for a SNA CCS TTY user.
User Response: A trace table entry (code x’160C’)
has been written that lists the VMDBK executing at the
time of the ABEND. R1 contains the address of the
head of the console task chain (RDEVCON). R6
contains the address of the console task (COMBK) that
was built to initiate a read. If the read had not
completed successfully, R1 and R6 would be equal. If
the read had completed successfully, the COMCNTL bit
would have been set in the console task pointed to by
R1. Since neither of these conditions are true, the head
of the console task chain has been corrupted. Examine
the storage pointed to by R1 and ensure this is a valid
COMBK address. Examine the contents of these
registers and the information contained in the trace
table entry to determine why the console task chain has
been corrupted.
VCS001
Explanation: HCPVCS issues this abend if the
console task (COMBK) address it is processing does
not represent a write operation for a SNA CCS TTY
user.
User Response: R5 contains the address of the
console task that was found to not be a console write.
R8 contains the RDEV address for the console that is to
be written to. Examine these registers to determine
what type of console task was being processed.
VCS002
Explanation: HCPVCS issues this abend if there are
more than two console read tasks active or queued for
a SNA CCS TTY user.
User Response: R8 contains the address of the
RDEV for the SNA CCS TTY console. The RDEV in turn
points to the address of the SNABK that also represents
the console. Examine the SNABK to determine what
reads were queued. A maximum of two reads should
exist; one representing a CP read and the other
representing a virtual machine read.
VCX001
VAT003 VCX001
Explanation: (soft abend) HCPVCX issues this abend
if an inter-user communication vehicle (IUCV) path for
SNA console communication services (SNA CCS) is
found to be incorrect. A path is found to be incorrect if
HCPVCX receives a IUCV return code indicating an
incorrect IUCV path ID when issuing an IUCV function
specifying this path.
User Response: R1 contains the address of the
IPARML/IXBLK. The return code is contained in the
IPRCODE field of the IPARML. The path ID of the
Chapter 2. System Codes 119
