I'm sure there are a number of NetApp customers that ask themselves
that question regularly.

It would be possible to re-implement the SCSI fencing script to use
preempt rather than preempt-abort, but I suspect the motivation for
prempt-abort is to prevent any outstanding i/o operations from
completing (because absent this, a successful preempt operation isn't
really equivalent to a fencing operation).  I'm not sure what the real
risks are in this situation.  Does anyone have any thoughts?
