You can run "scanner -m" on multiple tapes at once, but "scanner -i" has 
to be run in the sequence that the tapes were written to.

IOW, if you have 4 tapes #1, #2, #, #4, you can run "scanner -m" on all 4 
at the same time (presuming you have 4 tape drives). This will re-populate 
your media database with the information about the savesets on those 
tapes. However, if the saveset spans multiple tapes (#3, then #2, then #4) 
- you find the order by querying mminfo for the saveset you want - you 
will have to do a "scanner -i" on #3, then #2, and finally #4. That will 
rebuild the index, in the proper order.
