We have the robotic control on the master.

However, we use separate HBAs for the robot and drives than we do for
our attached disk storage.

This separate HBA has been a real boon because we have seen the HBA get
locked up on occasion and can simply reset that one HBA instead of
having to reboot the entire box.   Also it doesn't impact our disk
storage (e.g. NBU Catalogs) when we do the reset.  Now that NBU is using
a DB disk issues might be even worse than ever if they corrupt the DB so
I'd say the separate HBA is well worth the cost.

The reason I say a second HBA is that we will have 2 seperate fabrics.
 One will have all of the tape drives and robotic control and the
other is our disk fabric.
