Hi,
Best is to use zexplore Developpement Interface Utility to have more details.
This is an example in Python for retrieve subscriptions items and from there, you can unubcribe the member you need with api NaElement("storage-service-unsubscribe")
** Iterations subscriptions from storage service key
import sys
sys.path.append("<path_to_nmsdk_root>/lib/python/NetApp")
from NaServer import *
s = NaServer("ocum", 1 , 0)
s.set_server_type("DFM")
s.set_transport_type("HTTPS")
s.set_port(443)
s.set_style("LOGIN")
s.set_admin_user("admin", "<password>")
api = NaElement("storage-service-subscription-iter")
api.child_add_string("storage-service-resource-key","0ce429fe-4d45-4b3d-b9d7-4f9c27d1cc55:app_type=OCUM,type=storage_service,uuid=6adf153f-3702-4d8f-9df2-ade6f12bf4dc")
xo = s.invoke_elem(api)
if (xo.results_status() == "failed") :
print ("Error:\n")
print (xo.sprintf())
sys.exit (1)
print ("Received:\n")
print (xo.sprintf())
