UNT002 VAT002
program, and HCPUNT to determine why this occurred.
The SNAPLIST data contains the VDEV, RDEV, and
CPTCA control blocks. It also contains the RCWBK
control block chain and the failing host CCW.
UNT002
Explanation: (soft abend) The HCPUNT module
determined the start address of the host channel
program is not valid. The address is either negative, or
it indicates the first CCW falls below the RCWBK
header in storage. Channel program untranslation is not
performed.
User Response: Examine the soft abend SNAPLIST
data, the host channel program, the guest channel
program, and HCPUNT to determine why this occurred.
The SNAPLIST data contains the VDEV, RDEV, and
CPTCA control blocks. It also contains the RCWBK
control block chain and the failing host CCW.
UNT003
Explanation: (soft abend) The HCPUNT module
determined the SCSW CCW interrupt address is not
valid, because it points to the first CCW in a RCWBK.
Channel program untranslation is not performed,
because this should not have occurred.
User Response: Examine the soft abend SNAPLIST
data, the host channel program, the guest channel
program, and HCPUNT to determine why this occurred.
The SNAPLIST data contains the VDEV, RDEV, and
CPTCA control blocks. It also contains the RCWBK
control block chain and the failing host CCW.
UNT004
Explanation: (soft abend) The HCPUNT module
determines the channel program translation is not
performed, or the CPTCA control block address is zero.
Channel program untranslation is not performed.
User Response: Examine the soft abend dump, the
host channel program, and the guest channel program
to determine why IORCCWTR or IORCPTCA is zero.
The flag IORCCWTR and field IORCPTCA are located
in the IORBK control block.
USP001
Explanation: (soft abend) The LGFTRMLK lock was
destroyed while the logoff process was waiting to
acquire it.
User Response: Use the information in the trace table
and storage dump to determine why the lock was
destroyed.
118 z/VM: System Messages and Codes — CP
UTR001
Explanation: When the function was reverse
translating an address, the internal ASIT passed as
input failed certification. It was found to be an internal
ASIT for a CP address space, which should always be
valid.
User Response: Examine the location that contains
the fixed internal ASIT for the CP address space. It is
likely that the internal ASIT has been overlaid or CP has
incorrectly manipulated the internal ASIT.
VAI009
Explanation: (SOFT) A failure occurred while trying to
enable queue I/O assist. CP encountered an
unexpected error from the hardware when enabling the
assist. The system will recover, but performance may be
affected because queue I/O assist will not be enabled
for QDIO capable subchannels.
User Response: Contact IBM support.
VAP001
Explanation: (SOFT) A failure occurred while
processing an adapter interruption with the queue I/O
assist. CP encountered an unexpected error from the
hardware when processing an adapter interruption for a
virtual machine. The system will recover, but virtual
machines with QDIO subchannels may experience
problems.
User Response: Contact IBM support. Tun off the
hardware assist with the CP command, SET QIOAssist
OFF ALL.
VAT001
Explanation: The guest translation format is incorrect
or not supported.
User Response: Examine the CP trace table and
storage dump to determine why the guest CR0, which
contains the guest translation format control bits, is set
with an incorrect value before the call to HCPVAT.
VAT002
Explanation: (soft abend) HCPVATRN was called to
translate a guest address without specifying a segment
table designation, and the guest PSW was in access
register mode. HCPVATRN supports translating guest
addresses while in access register mode only when a
segment table designation is specified.
User Response: Determine why the caller (R14) of
HCPVATRN requested a translation of an address, and
the guest PSW indicated the guest is in access register
mode. Also, determine why a segment table designation
for translation was not provided.
