Wilie, You are correct.
Since the problem is with a PROCLIB, restoring it to the same Volume is not as relevant as restoring to the same TTRs. If it gets restored to the same volume, but not the same TTRs, then you will still need to open/close proclibs in-order to get JES2 to refresh its information. For any other type of dataset, it should work.
