Checking the NSR operation field will do what you ask. Something like :
nsradmin -s $SERVER -i - <<EOF
option hidden
show name ; NSR operation
print nsr device
EOF
But this not really what you need. An idle drive is not enough when it comes to
modifying pools : as the "update failed" error below in your message shows, a
tape mounted in it, even if it is not actively used, prevents the update.
You could try to eject whatever may be in the drive (nrjb -u -f ...) and check
if that gives a "device ... is busy" error ; if not, the device is eligible for
the update.
