Thanks to those who responded to my two questions.  But alas, I think I
asked the first question wrong, and yet a new (third) question arises:  My
first question should have been: What's the difference between Restore
Stgpool and Restore Volume (why does the manual say to use Restore Stgpool
when it is but a single volume I've lost)?  New question: Now that the
files from the destroyed volume have been successfully recovered and the
destroyed volume has been deleted from ADSM, is my last remaining task to
do a Checkout Libvol in order to make our 3494 ATL "forget" about the tape?
