Others have made excellent points. The bottom line is that there is no good technical solution. Sharing DASD and catalogs brings problems like yours. Not sharing DASD brings business problems.
The 'best' technical solution is a totally isolated LPAR with only its DASD online. Many of us can't do that, so we live with the consequences. For your case, I'd suggest finding out what is causing the reserve and see if using GRS to convert the reserve to an enqueue is suitable for you. Sometimes full pack backups cause these kinds of problems. Consider routing those jobs to LPARS that can own a reserve and not hurt anything.
