Thats not possible without some help... what I would do is use an external script to achieve this behaviour. A script that could be run from an admin job before your daily jobs start could do the following: Check how much space is left on the currently available disk (using df, probably). If it's less than a given amount or percentage, issue "purge volume=<label>" commant to bconsole. Check the output, create a readable report. I think I would even make sure the volume file has a minimum age, so that the most current jobs will not get overwritten.

Good reason, but how your volume changing is implemented depends on your usualy procedures and how the operator like to work... for simple "tape-changing grunts" I'd use something different than for the clever admin type of operators :-) (no offense to any operators - I know you've got lots of other stuff do do, typically.)
