volume-get-iter (SDK 5.7) doesnt shows all volumes under cluster(9.1)

Hi Guys,

I am using Netapp SDK 5.7 and below is the sample python code. If I try to list all of the volumes under the cluster it shows only 50+ or sometimes 200+ volumes. I could confirm that the cluster(version 9.1) has 1000+ volumes.How could I list all the volumes?

s = NaServer("x.x.x.x", 1 , 31)
s.set_server_type("FILER")
s.set_transport_type("HTTPS")
s.set_port(443)
s.set_style("LOGIN")
s.set_admin_user("someuser", "somepassword")



result = s.invoke('volume-get-iter' , 'max-records', 1000)
print(result.sprintf())  



for volume in result.child_get('attributes-list').children_get():
       volumename = volume.child_get('volume-id-attributes').child_get_string('name') 
       print(volumename)


#Below are the last few output lines of sprintf() 

		</volume-attributes></attributes-list><next-tag>&lt;volume-get-iter-key-td&gt;&lt;key-0&gt;vserver1&lt;/key-0&gt;&lt;key-1&gt;vol101&lt;/key-1&gt;&lt;/volume-get-iter-key-td&gt;</next-tag><num-records>250</num-records>  </result>

Looks to me "next-tag" says there is a volume vol101 being followed up and this time it prints 250 volumes(this number changes everytime running the script). How can I print all of the volumes from the cluster? Why max-records parameter doesnt helps here?

I am not able to get "next-tag" working if this is the only way. Please help me to modify or add any code that would help. Thanks in advance.

Regards,

Joy
