True but this could also be done with /dev/c0t0l0 (c = controller, t = target, l = LUN) And I was mainly arguing against the previous writer's insistance that having equally cryptic names will help Linux compete in business.

It sort of does as if this is implemented then the old naming sceme will probably be "depricated".

It would probably take a second to do
dmesg | grep sda and read off the information
or
grep sda /var/adm/syslog and read off the information
