A colleague of mine on another computer system asked me to forward the following problem about magnetic tape ACPs under VMS V4.x. If anyone can help out, I would appreciate it. > In Version 3.x of the VMS operating system, if you wanted to write > (or read) a volume set of magnetic tapes, it was basically your respon- > sibility to initialize the volume set prior to it's use. For example, if > you wanted to write one large file out onto three tapes, those three tapes > must have been initialized as a volume set and mounted as a volume set. > If, after writing on the third tape, you realized it was going to take four > tapes, you were out of luck, VMS couldn't initialize the fourth tape with tape with > a pending write request. > > A new feature of VMS version 4.0 is that the magnetic tape ACP will > automatically ask the operator to mount a relative volume n+1 if it > hits the EOT mark and there is a pending write (or read) request. Thus, > you no longer have to create and mount a volume set, VMS will create it > for you as you go along. > > The problem I am encountering is that after the first tape is written, > an operator request goes to the console which says "Please mount relative > volume 2 (VOLNAM) on device x". At that point, no matter what tape is > mounted on the drive, it will not recognize it as relative volume 2. > I have tried a blank tape and the REPLY/BLANK_TAPE= reply, I have tried > a scratch tape and the REPLY/INITIALIZE= reply, and I have tried initializing > the volume myself to the label it is looking for and using the REPLY/TO= > reply, none of these approaches has worked. I will pass along any input I receive. Thanks in advance. Ron Tencati JPL-VLSI.ARPA

From: pyoung.pasa@Xerox.ARPA You will be able to mount continuation volumes without REPLY/INITIALIZE or REPLY/BLANK if you include /INITIALIZE=CONTINUATION with your original mount request. I experienced the same problems that you described, found this solution, but am left wondering why REPLY/INITIALIZE didn't work (it keeps on prompting for the next relative volume). Phil Young
