We still use TMS to manage the virtual tapes. If something like this were to have happened to us, the tapes would have gone scratch. There is no operator intervention. We have a code gateway for passing scratch tape VOLSERs to the VTL. Any anomolies have to be caught in the code or the volumes go scratch. With tape, you can recover the data if the volume hasn't been overwritten. With the VTL, probably not. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
