Restoring a logical file just restores the file. The access path

Unless the file was saved with ACCPTH(*YES), I think.
No. Access paths only get saved with, and only restored with, the
actual physical data. Necessarily so, because the access paths are
intrinsically tied-to the data; they in fact contain an identical copy
of the physical data for every key value along with correlation to the
specific row of physical data. Restore just the logical file, and the
system does not know what is the current data [and will not presume to
know that what is on the system is identical to what is on the media],
so the keyed Access Path (ACCPTH) *must* be rebuilt over the /new/ data.
