Don't do that.  But now that it is done...
Causing a reinventory of the 3494 should do it, but less drastic
would be to use the mtlib command to change the category code to
FFFB, to delete the Library Manager database entry, as for a
Manually Ejected (FFFA) volume.
I presume from your posting that these volumes were not known to
ADSM, else you need to take appropriate action there as well.
