HSC needs to avoid marking the tapes as non-scratch in this situation, HSC/SMC get involved at allocation so they are out of the picture at that point. All HSC knows is a tape was mounted so it marks it non-scratch in the CDS to preserve integrity. HSC would probably need to add hooks into the system like other tape management software does to do more. > >Has anyone developed or seen a solution for this, or even things which >would help? Write procedures so you don't forget. Put a note in the TAPEREQ member to remind you to check TMONSMxx when you make changes. I've never run into this but I haven't worked at a shop that used TMONSMxx in a long time. I just let TAPEREQ control what type of media (virtual, physical 3490, physical 9840 etc.).
