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

HCP6817E HCP6818E
System Action: The dynamic I/O support is not
enabled on the system.
User Response: Contact your system programmer.
System Programmer Response: Run the IOCP
source file through the IOCP utility provided on the
CMS disk specifying the DYN option. This will add
the correct configuration token to the IOCP file. Then
write the generated IOCDS to the PCE hard disk.
Shutdown and re-IPL the system.
v Dynamic I/O changes are being controlled by
HCD.
Explanation: A QUERY DYNAMIC_IO command
was issued to obtain dynamic I/O status to determine
if this VM system is enabled for dynamic I/O.
However, the system was IPLed with HCD enabled
for dynamic I/O and VM’s dynamic I/O command
interface is therefore unavailable for use while HCD
is enabled.
System Action: System operation continues.
User Response: Issue the QUERY HCD command
to obtain HCD dynamic I/O information. If you want
VM to control the dynamic I/O configuration instead
of HCD, then issue the DISABLE HCD command.
Note that the DISABLE HCD command disables
HCD’s control of the hardware and software I/O
configuration. HCD can be re-enabled only by
re-IPLing the system.
v Hot I/O rates are being controlled by HCD.
Explanation: A QUERY HOTIO command was
issued to obtain the hot I/O rates for devices in the
system. However, this system was IPLed with HCD
controlling the software I/O configuration. Therefore,
the SET HOTIO and QUERY HOTIO commands are
unavailable for use.
System Action: System operation continues.
User Response: To retrieve the hot I/O recovery rate
setting information, either use HCM or the HCD OS
device detail report. The hot I/O recovery rate
corresponds to the UIRATE device parameter. In
HCM, the ‘OS Configuration Parameters’ dialog
allows you to view/modify this setting. For more
information about HCM, see the z/OS and z/VM:
Hardware Configuration Manager User’s Guide. To
print the HCD OS device detail report, the REXX
utility CBDSREP can be used. For more information
about how to print HCD reports see z/VM: I/O
Configuration. If you want VM to control the I/O
configuration instead of HCD, issue the DISABLE
HCD command. Note that the DISABLE HCD
command disables HCD’s control of the hardware
and software I/O configuration. HCD can be
re-enabled only by re-IPLing the system.
v Dynamic I/O changes are not allowed for CSS nn
Explanation: The dynamic I/O command that was
issued failed because a channel-subsystem (CSS) ID
specified is for a channel subsystem that does not
support dynamic I/O changes.
System Action: System operation continues.
406 z/VM: System Messages and Codes — CP
User Response: Verify the dynamic change you are
trying to make and, if appropriate, re-issue the
command specifying a CSS ID for a channel
subsystem that supports dynamic changes.
HCP6817E You must specify an existing CP
command for this alias
Explanation: CP rejected the request to define a new
alias for an existing CP command because you did not
specify which existing CP command.
System Action: CP does not define a new alias;
system operation continues.
User Response: Define the alias again, and
remember to identify the existing CP command for
which you are creating the alias.
Important Note
If you did not use the CP DEFINE ALIAS
command or configuration file statement to define
a new alias, then an internal error has occurred.
Contact your IBM software support for
programming support.
HCP6818E The variations of this message are
explained below.
MESSAGES:
v Vary command failed. Channel path path is
logically online
Explanation: A user entered the VARY CHPID chpid
OFF command, but the specified path is logically
online to one or more devices.
System Action: The CHPID is not varied off.
User Response: Enter the VARY PATH OFF
command to vary the path off from all devices. Then
enter the command again.
v Delete command failed. Channel path path is
physically available
Explanation: A user entered the DELETE CHPID
chpid command, but the specified path is physically
available to the system.
System Action: The CHPID is not deleted.
User Response: Enter the VARY CHPID OFF
command to vary the CHPID off from the system.
Then enter the command again.
v Delete command failed. Device rdev is not
subchannel offline
Explanation: A user entered the DELETE DEVICE
command, but the device or devices were not varied
subchannel offline.
System Action: The device or devices are not
deleted.
