We had one at NVIP. I believe my first performance problem was related to slowness early on after the online came up. One of the files ended up on MSS and the first time through was delayed by waiting for back end staging to the 3350s, I believe we had 2 staging devices. Of course after staging things were, well, better. I still have one of those bullets laying around somewhere. I forget what process would run that would validate the bullets and make that wrapping noise. I had access to the hardware and was in the room when this kicked off. Kind of jumped the first time I heard it. Seems we had quite a variety and never thought to list it and IBM was on-site all the time. Miss those days a bit.Sorry for the traipse down lane but I've often wondered what the tape drive was called that had a front/top cover like a roll top desk. I think it was IBM.Sent from my Verizon, Samsung Galaxy smartphone-------- Original message --------From: Seymour J Metz <[email protected]> Date: 4/25/21 12:17 PM (GMT-05:00) To: [email protected] Subject: Re: Diagram of MVS Control Blocks IBM uses both the term Mass Storage Facility and the term Mass Storage System.
