I am not sure whether your procedure will also work for expired save sets. I 
would do it with this sequence:

  - scan the media (scanner -m) to get the SS info into the MDB.
  - set the browse- and the retention time to a future timestamp.
  - scan the media (scanner -i) to get the CFI information or use "nsrck -L7 -t 
time" assuming the the NW server 'knows' this media already, especially if the 
index backups reside on a different volume.

This will work for sure. Unfortunately, if you must use scanner, you must run 
the program twice.
