While this system was trying to join the sysplex it detected that it is running on the same CPC image as the active system sysname. It has attempted to initiate the partition of that system. It will wait for the partition to complete and attempt to join the sysplex again.

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.
