Printap

The command printap takes devices as arguments and will print all the paths to that device that it can find on the system.

$ /opt/SUNWdiskomizer/bin/printap /dev/rdsk/c0t65d0s0
Logical path /dev/rdsk/c0t65d0s0
/devices/sbus@2,0/SUNW,socal@2,0/sf@0,0/ssd@w21000020370f3f55,0:a,raw
/devices/sbus@2,0/SUNW,socal@d,10000/sf@0,0/ssd@w22000020370f3f55,0:a,raw

You can have it search an alternative /devices tree by specifying the -d option.
