I asked a Sun engineer but even he was not sure about how to get to the
disk from the path. He said they generally to a format-analyze-read on a
neighbouring disk to see
the lights blinking.

Subject: How to find the slot on I/O board from c?t?d?s?
I need to know which sbus slot (0,1,2) on the I/O board a disk is connected
to.
I have a disk c2t3d0s0
If a do a ls -l on /dev/rdsk/c2t3d0s0 it gives me
sbus@3,0/QLGC,isp@0,10000/sd@3,0:a,raw

------> This number divided by 2 gives me the board number
(3/2 =1)
How do I get the slot number on this board.
Actually this disk is in a RSM tray.

>The Sbus slot number follows the "isp@", so in your case is slot 0. This
