IXC231I

Explanation
This system has stopped waiting for system sysname to
be partitioned from the sysplex.  This system will not be able to
join the sysplex until system sysname has been
partitioned out of the sysplex.
Note that this message might
be issued if you have altered the TOD clock or sysplex timer to a
time earlier than the system previously was using. If either the TOD
clock or the sysplex timer has been regressed, you can avoid this
message by waiting the amount of regressed time before re-IPLing or
by reformatting the sysplex couple data set.
In the message
text: sysname
The system name of the system that was previously running on the
same CPC image as the current system.

System action
The system issues prompt IXC207A requesting that
you specify a new COUPLExx parmlib member to restart XCF initialization.
The system also issues IXC218I and IXC203I, which give additional
information about the system and the sysplex.

Operator response
Respond to message IXC207A, specifying the
new COUPLExx parmlib member.  IXC218I and IXC203I contain information
that can be used to respond to IXC207A.
