Do you have the following in your kernel config file: device pass0 And have you made the transport layer device and the passthrough devices? cd /dev sh MAKEDEV xpt1 sh MAKEDEV pass8 > > > What is the default number of tags per device?

Seagates generally have 63 tags. Justin says that the reason you got the "tagged openings now 8" message for your Fireball ST is because it returned Queue Full as soon as we tried to give it 9 outstanding transactions. That fits with my experience -- those drives can only handle 8 tags.
