I think there is an error in the doc. The default level 2 behavior is (supposed to be) synchronous. DirMaint will poll, waiting until the flashcopy is complete before reporting "Done". Level 1 causes DirMaint to issue the CP FLASHCOPY command (without the new SYNCH option). The CP FLASHCOPY command is yours to play with, too, but you need class B. Please contact the Support Center so that we can get to the bottom of things. Alan Altmark z/VM Development IBM Endicott
