The vendor of the pseudo tape unit has changed several things in the response during a Detach so that CP now issues only a single message, "HCPERP2215A TAPE 0670 REQUIRES OPERATOR INTERVENTION; MAKE DRIVE READY", which brings up a question. Why does CP care that the drive is not ready when it is detached? What will get mounted the next time the drive is attached is unknown, so he Ready/Not Ready state is not too important at the time of the detach. At the very least, this is not an item that requires immediate action.
