IXC412I

Explanation
This system tried to IPL with one of the following
sysplex configurations specified: XCF-local
MONOPLEX
Multisystem

This configuration is not compatible with the
system configuration, or the sysplex that is defined by the COUPLE
system parameter, because of one of the following: The PLEXCFG system parameter is not compatible with
the sysplex configuration for one of the following reasons:PLEXCFG does not allow XCFLOCAL, and COUPLExx does not have a
PCOUPLE statement (or COUPLE=** is used).
PLEXCFG only allows XCFLOCAL, but COUPLExx has a PCOUPLE statement.
PLEXCFG only allows MONOPLEX, but at least one system is active
in the sysplex.
PLEXCFG does not allow MONOPLEX, but the system is in the local
timing mode.

Another system component has imposed restrictions on the sysplex
configuration that is allowed because of other system parameters. For
example, If GRS=NONE is specified in the system parameters, the system
cannot IPL in multisystem mode.

System action
The system issues other messages
explaining the incompatibility and prompts the operator with IXC420D
or IXC207A to allow the sysplex to be re-initialized or a new COUPLE
system parameter to be specified.

Operator response
Notify the system programmer.  At the request
of the system programmer, do one of the following: Specify a different COUPLE system parameter to allow
this system to join the sysplex with the current system configuration
Have the system programmer change the system parameters of this
system to allow the desired configuration.  Then re-IPL the system

System programmer response
See the system programmer response
for any accompanying messages.  Do one of the following: Have the operator respecify the COUPLE system
parameter.  For example, when a system is trying to IPL in a
multisystem mode, but the COUPLE system parameter in
use does not provide a couple data set, specify another COUPLE
system parameter for a parmlib member that does define a couple
data set.
Change this system's system parameters to match the sysplex the
system is trying to join. Then have the operator reIPL the system.
