So let me get this straight, you removed the first SCSI adapter, before 
placing the second in the system?

If you had a spare pci slot, I might have installed both cards at the 
same time
Do a devfsadm -Cv (which will create and clean up any dead links from 
/dev to /devices), changed up /etc/vfstab, shutdown.
Pull out the original card.
Bring solaris back up, and do another devfsadm -Cv (now this time doing 
a cleanup of the devlinks from the old HBA)

Its neat to know the simlink method can work.  Ideally you could save a 
reboot here... but it sounds like a PIA to me though :-)

PS.  Don't forget to update dumpadm
