IEE239I

Explanation
A CONFIG command requested that the system reconfigure
a CPU or core online or offline.
The system was unable to perform physical reconfiguration because
the service processor detected an error condition.
In the message
text:
SERVICE PROCESSOR BUSY
The service processor could not process the CONFIG command because
it is processing another request.
REQUIRED SYSTEM RESOURCE NOT AVAILABLE
The system could not process the CONFIG command because a software
resource needed by the service processor was in use.
SERVICE PROCESSOR FAILURE
The service processor could not process the CONFIG command because
of an internal service processor error.
SERVICE PROCESSOR ERROR
The service processor indicated that the central processor reconfiguration
hardware is not installed; however, the hardware indicators show that
the CPU or core reconfiguration hardware
is installed.
TARGET HARDWARE ERROR
One of the following occurred: An error occurred during a target equipment check that is associated
with the resource being configured or deconfigured.  The state of
the resource changed.  The error is not associated with the service-call
logical processor (SCLP).
An error occurred during a target equipment check that is associated
with the resource being configured or reconfigured.  The state of
the resource did not change.  The error is not associated with the
SCLP.

{CPU|CORE} ID NOT RECOGNIZED BY SERVICE PROCESSOR
The service processor did not recognize the CPU or core identifier;
however, the hardware indicators show that this identifier is valid.
{CPU|CORE} NOT AVAILABLE
The specified CPU or core is not a part of this
configuration.
{CPU|CORE} IS POWERED OFF
The specified CPU or core is powered off.
WOULD REMOVE LAST {CPU|CORE}
The standard CPU or core cannot be reconfigured
offline because it is the last standard
CPU or core.

System action
Depending on the value of text,
the system does the following: SERVICE PROCESSOR BUSY
REQUIRED SYSTEM RESOURCE NOT AVAILABLE
SERVICE PROCESSOR FAILURE
SERVICE PROCESSOR ERROR
{CPU|CORE} ID NOT RECOGNIZED BY SERVICE PROCESSOR
The system does not reconfigure the CPU or core online
or physically offline. If the request was OFFLINE, the system takes
the CPU or core logically offline.
{CPU|CORE} NOT AVAILABLE
The system does not reconfigure the CPU or core online
or physically offline.  If the request was OFFLINE, the CPU or core is already offline
in another configuration.
{CPU|CORE} IS POWERED OFF
The system does not reconfigure the CPU or core online.
WOULD REMOVE LAST {CPU|CORE}
The system does not reconfigure the CPU or core offline.
{CPU|CORE}(x) NOT ONLINE
The system does not reconfigure the CPU or core online.

Operator response
Do the following: Enter DISPLAY MATRIX=CPU to display the status
of CPUs (when LOADxx specifies PROCVIEW CPU) or DISPLAY MATRIX=CORE
to display the status of cores (when LOADxx specifies PROCVIEW CORE).
For more information on the DISPLAY command, see z/OS MVS System Commands. 
Depending on the value of text, do the following: SERVICE PROCESSOR BUSY
REQUIRED SYSTEM RESOURCE NOT AVAILABLE
SERVICE PROCESSOR FAILURE
Enter the CONFIG command again. If the problem recurs, contact
hardware support.
SERVICE PROCESSOR ERROR
{CPU|CORE} ID NOT RECOGNIZED BY SERVICE PROCESSOR
Contact hardware support.
{CPU|CORE} NOT AVAILABLE
Make the specified CPU or
core a part
of this configuration. Enter the CONFIG command again.
{CPU|CORE} IS POWERED OFF
Make sure the CPU or core is powered on. Enter
the CONFIG command again.
WOULD REMOVE LAST {CPU|CORE}
Check the status of the CPU
or core.
{CPU|CORE}(x) NOT ONLINE
Make sure the specified CPU
or core is
online. Enter the CONFIG command again.
