AFAIK, for tape it shouldn't cause any more harm than the target reset
which
happens immediately before it. This patch is infinitely better than the
previous "bus" reset behavior.
That said, its far from perfect. The code (as I understand it) isn't
differentiating between isolating the failure, or bringing out the big
hammer in an attempt to correct problems on a specific I_T_L. If you
drop/reset the I_T because one of the LUN's is misbehaving before verifying
the status of other LUN's on the target, you risk interrupting operations to
functional devices.
