With Sun, sd0 is a disk and sd0,a is a slice on that disk. The file /etc/path_to_inst will tell the hardware path of sd0:
grep ' 0 "sd"' /etc/path_to_inst
On one of my systems I get,
"/sbus@1f,0/SUNW,fas@e,8800000/sd@0,0" 0 "sd"
To find the special files that refer to that disk, just do a "ls -l" and grep for that string:
ls -l /dev/dsk/* | grep "/sbus@1f,0/SUNW,fas@e,8800000/sd@0,0"
However, I think that you should consider iostat rather than sar. iostat -x will give you better stats than sar. iostat -xp will make that a line of stats for each slice. And iostat -xpn will rename the lines with the special file names, thus saving you from this whole exercize.
