Actually, the lowest priority on the list is, unfortunately, the most important
is dealing with the "need a tape" situation: "checki libv...stat=scr".  There's
nothing like the call from operations in the early hours of Sunday that you're
dead from lack of scratch, because somebody in a building far from yours has
attached a storage array in the 1-2 Tb range to a registered client before he
left on Friday afternoon.  Even after a "dsmserv extend log...", there's still
a scramble to get the empty volumes the operator found stashed in the corner
actually made usable in the library.  Such a recent Sunday for me ran to 17
hours, so, if I were King of the Forest, "checki libv..." would have the
highest priority of all.
