(1)A TSO command can be executed to retrieve and display the current FC state of a drive. I believe there is also an operator command. (2) When the volume copy is complete, an unsolicted state change interrupt is sent by the control unit to all attached systems. Software in MVS (AOM - the Asynchronous Operations Manager) recognizes the state change interrupt, immediately queries the device to get its new full status, and updates appropriate MVS control blocks where the status is stored (at least the DCE - DASD Device Class Extension). A system event could be generated by this same software for the Event Notification Facility to intercept. Sounds like a good SHARE requirement to me. Bill Fairchild "Facts are the enemy of truth."
