    They said Apollo
    DN580 can only read Quick 24 format tapes and not Quick 11 tapes.
    Apollo said that it is dip switch setting on the SUNs.

I have gotten this to work in the past.  The problem is indeed QIC 11 vs 24.
As I recall, the Sun I used was capable of writing the correct format simply
by specifying a different minor device number (/dev/rst8?).  Check your
Sun manual; that's how I figured it out.

I think Sun has at least two different cartridge tape controllers, and it
may indeed be a dip switch option on one of them.

For the record, we use the more modern of the two standards.  The manufacturer
apparently considers the other one (QIC 11?) obsolete, and we didn't think
about compatibility with non-Apollo equipment that uses the older standard.

The great thing about standards is that there are so many to choose from.
