na_ontap_volume_lock_module ?

Hello, 

I would want to show and break some locks file between cifs share. But I can't locate the module associated for that function.

vserver locks show -vserver <vserver_name> -volume <volume_name> -path <folder_path>
vserver locks break -vserver svm-pca-nas -volume VolumeName -path 


Could you advise  ? 

Regards
