in reply to Need to find mount point for device.

Untested, but I'd do something along the lines of:

Run a recursive detailed listing of /dev and grep for the major & minor numbers - in this case 283 & 0 e.g. find /dev -ls | perl -ne 'print if /\s283,\s+0\s/' - this will give you the dev entry e.g. /dev/c1t2d3s0, then simply grep this out of the mounted device list e.g. mount | grep '/dev/c1t2d3s0'.

A user level that continues to overstate my experience :-))
