Our site used to get this too, assigning volumes from the wrong pool. Immediately after you get the error message see how many scratch tapes you have and how many in the various sub pools. You might be running faster than the VTS is scratching tapes. -- Mike A Schwab, Springfield IL USA Where do Forest Rangers go to get away from it all? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
