Look at the DEVNO option of the MDISK statement in the directory. That lets you use the device address. If you think you don't need VM MDC for them, you could just dedicate them (and have the (dup) volser not attached to SYSTEM). If you want to be completely isolated, you should start the mini disks at cylinder 1 so CP is free to use volsers that work for the entire installation, where TPF can have its own (virtual) volser. But you may not be in a position anymore to pick that approach. Rob
