Can Nagios check Netapp LUNS

I can get the check_netapp command to check the volumes which it is supposed to do, so that is fine.

But can it check LUNS, this is imperitive as Server instances rely on the LUN as well as space in the volume

Ideally I want to check the space usage.

libexec]# ./check_netapp -H 172.1.1.1 -C xxxxx -v DISKUSED -o /vol/vol_mp/mp/mp.lun -w 80 -c 90
DISKUSED UNKNOWN - unknown volume: /vol/vol_mp/mp/mp.lun|

libexec]# ./check_netapp -H 172.1.1.1 -C xxxxxx -v DISKUSED -o /vol/vol_mp/mp/ -w 80 -c 90
DISKUSED UNKNOWN - unknown volume: /vol/vol_mp/mp/|

libexec]# ./check_netapp -H 172.1.1.1 -C xxxxxx -v DISKUSED -o /vol/vol_mp/ -w 80 -c 90
DISKUSED OK - /vol/vol_mp/ - total: 1536000 Kb - used 37688 Kb (2%) - free: 1498312 Kb|/vol/vol_mp/;1536000;37688;1498312;2

So you can see it works for the volume, but not the LUNS??

Anyone succeeded with this before?
