Error description
You are restarting many of your CMASs simultaneously after running the EYU9XDUT utility against their EYUDREP data sets. You receive messages indicating the repository resync process has failed, and that one or more of your CMASs are being isolated. Some of the messages in the CMAS job output related to this event may include the following (not all messages in each CMAS) EYUCP0033I cmasname Disconnect requested for CMAS cmasname2. Reason: CMAS isolated. EYUCP0207E CICSplex plexname on CMAS cmasname cannot be redefined as MASes are active on CMAS cmasname EYUCP0205S plexname Repository Synchronization with CMAS cmasname failed. EYUCP0011E cmasname Repository synchronization failed for one or more CICSplexes. This CMAS is being isolated at the request of CMAS (cmasname).
Local fix
Simply restarting the isolated CMAS may bring it back into the CICSplex network

These can be * * done in any order. * **************************************************************** When multiple CMASs connect to the Maintenance Point (MP) CMAS at the same time, and one of its CMASs has had its EYUDREP upgraded using the EYU9XDUT utility, then it is possible for other CMASs, that have MASs active, to be isolated. This problem is due to timing between the multiple CMASs connecting, including one where the data repository has been updated in the described manner. It could also occur if no definitional updates have been made to the CICSPlex SM data repository for at least two week prior to the CMAS restart. Method CPLT (EYU0CPLT) reread the CICSplex level, CPLXCMAS_SYNCDATA, just before it was used so it knew about the latest changes. However it didn't know about MPSYNCCR record additions in some cases, leading to delete/define of the remote CICSplex definition and possible CMAS isolations as the new data was propagated.
Problem conclusion
This APAR rereads the MPSYNCCR records available info, CPLXCMAS_FSYNC, just before it uses it so it knows if it can do an incremental upgrade of the CICSplex rather than a delete/define, which can be more disruptive.
