IBM developers: Are you listening?
It would be wonderful to be able to preview a restore so as to preload all the
tapes needed for the restore. Some of us have servers with libraries too
small
to keep all of a primary storage pool online (e.g., 3570-B11 or -B12).
Would a hairy SQL query do as a workaround?
