I used the tedious dd approach recently.  It is best done in advance 
of deployment when the system is idle.

I found that 'cfgadm -al' (or something like 'cfgadm -al c17' once the 
controller has been identified) is useful since it provides 
identifying information which can be correlated with 'zpool status' 
and 'iostat -Ei'.

While replacing a failed drive on my 20 drive server, I realized that 
it is wise to figure everything out in advance while everything is 
working properly.

Having to do this is really crummy.  It would be nice to have a way to 
turn the location LED on for popular server platforms.
