scsibus at? target at?

["David B." <incomex_(_at_)_hotmail_(_dot_)_com>]

installing a raidframe.  raid(4) says I have to hardcode the devices and not 
use sd4a, etc.  When I boot, the screen scrolls by so fast I can't see what 
scsibus the /dev's are attached to.  My primary is obviously scsibus0, 
currently with 4 targets, 0 through 3, found at sd0-3; however, I have a 
Qlogic 2100 FC-AL HBA to which my SAN array is attached with 12 fiberchannel 
drives.  These drives are sd4-15.

Is there a command or a utility I can use to see what scsibus and target the 
drives are attached to? or is it a default that the primary be scsibus0 and 
the Qlogic HBA be
scsibus1?  If I add another scsi controller to the pci bus, does that change 
anything?
or is everything automatically attached to scsibus0, and in this case the 
targets are
going to have the same numbering as the devices?  (e.g.  sd4 is scsibus0 at 
target 4)

thanks
