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

HCP6852E HCP6857I
HCP6852E The variations of this message are
explained below.
MESSAGES:
v System is exiting configuration mode because
user userid is logging off. The I/O configuration is
no longer valid
Explanation: A user logged off while in configuration
mode. LOGOFF processing forced the system out of
configuration before allowing the user to logoff.
System Action: The system is taken out of
configuration mode and the configuration is left not
valid.
User Response: None.
System Programmer Response: Find out what
changes were made to the I/O configuration. If the
changes are consistent with the current IOCDS, enter
the SET CONFIGMODE ON RESET command to
reset the valid bit in the channel subsystem. Then
enter the SET CONFIGMODE OFF command to get
out of configuration mode.
v Logoff processing could not take user userid out
of configuration mode
Explanation: A user logged off while in configuration
mode. LOGOFF processing tried to get the system
out of configuration mode, but failed. The message
prior to this one will have the cause of the failure.
System Action: The system is not taken out of
configuration mode, but the user is logged off.
User Response: None.
System Programmer Response: Find out why the
system could not be taken out of configuration mode
from the error code in the previously issued
message. A re-IPL or POWER OFF and then ON of
the machine may be necessary to fix the problem.
HCP6853E CHPID chpid has been created but is in
definition error and will be unusable
when varied on
Explanation: A user entered the DEFINE CHPID
command, and the type specified for the CHPID does
not match the actual physical CHPID type.
System Action: CHPID is created, but is unusable
when varied on.
User Response: Delete the CHPID using the DELETE
CHPID command and enter the DEFINE CHPID
command again using the correct CHPID type.
HCP6854E CU cu has been created but is in
definition error. Devices on the CU are
not operational and cannot be varied
online.
Explanation: The DEFINE CU or MODIFY CU
command was entered with specified channel paths that

do not match the physical configuration or are otherwise
invalid for this CU.
For the S/390 ®
Multiprise ®
2000 Internal Disk, you
specified two channel paths that do not correspond to
the actual channel paths for the mirrored DASD.
System Action: CU is created, but the CU and its
devices are unusable.
User Response: Delete the CU using the DELETE
CU command, and enter the DEFINE CU command
using the proper channel paths. Alternatively, use the
MODIFY CU command to change the channel paths
associated with the CU.
HCP6855E Command cannot be processed for
device operand because the
subchannel cannot be modified
Explanation: You have entered an I/O related
command, such as SET SCMeasure. As part of the
command processing, CP must issue an MSCH to
modify the subchannel. If that I/O cannot be done, this
message is issued. This often indicates that the device
is actively doing some other I/O. There are some types
of devices that have a type protocol that makes CP
think they always have active I/O. Some examples
would be bisync devices, serial channel-to-channel
devices, and integrated adapters.
System Action: CP rejects the request; system
operation continues.
User Response: Select a different device, or change
the circumstances under which the current device is
being used.
HCP6856I Cannot measure subchannel for device
device
The subchannel cannot be modified
Explanation: During system initialization, an attempt is
made to enable subchannel measurements for the IPL
device. As part of that processing, CP must issue an
MSCH to modify the subchannel. If that I/O cannot be
done, then this message is issued. This often indicates
that the device is busy.
System Action: CP rejects the request. System
operation continues.
User Response: After the IPL completes, you can try
to enable the device for subchannel measurements by
using the SET SCMEASURE command.
HCP6857I System is {enabled|disabled} for
dynamic I/O changes
Explanation: The FEATURES ENABLE or DISABLE
DYNAMIC I/O statement was coded in the system
configuration file. This response indicates that the
