Has anyone got a utility or a method of determining which physical files
have a logical over them that is stored in a different library?   Other than
checking each one! ;-)

There's a command in TAA Tools called Check Database Dependances (CHKDBD).

Obviously, the logicals won't restore if the physical isn't there.....
A good rule of thumb is to *NEVER put a logical into a different library, however if you must (sometimes there are business reasons), then to put the logical in a library higher in alphabetical order than the library of the physical.  In this case, the logical will restore, but the access path will have to be rebuilt (if there was one, which there typically is), even if you saved with ACCPTH(*YES).

BTW, you should never *ALWAYS save access paths by specifying ACCPTH(*YES) on the SAVLIB, SAVOBJ and SAVCHGOBJ command unless you are *SURE that the access path(s) won't restore (i.e.: physicals and logicals in different libraries).
