In my experience it's fact.  I have never used a SCSI stack which both
supported AND used linked commands.  Like some others here, I always
assumed AIX might :^) Ralph has pointed out that T10 is well aware
that the feature is not popular.  There are other ways of
accomplishing the same thing that are less likely to blow up in your
face.

I don't know, but I'd be really surprised if they did use linked
commands.  You have to be pretty nuts to rely on a feature that's not
even exercised by most SCSI implementations.
