OnTAPI lun-get-iter fails with error 13001 on 8.3.1

pipatel · ‎2015-11-12

When iterating through the LUNs using lun-get-iter() we are getting

Error 13001 during lun-get-iter() :
Parsing error in results: Start tag expect, '<' not found

Looking at TCP dumps reveal that the XML is malformed

This is happening on both sumulator and appliance. We've tested it several times and garbage appears at same place with same or different characters.
Has anyone seen this?

Thanks,

I got the same problem. See my question at http://community.netapp.com/t5/Software-Development-Kit-SDK-and-API-Discussions/Cluster-Mode-8-3-1-sending-HTTP-chunked-response-and-broke-Manageabili...

Hi Leo,

Could you tell me how you switched this off using the NMSDK5.4P1 as in the commands?

Cheers

@pipatel have you get the resolution of this issue.

i am also facing the same with python NMSDK

Can you first try in ZEDI without any options. Python code like this is working for me.

api = NaElement("lun-get-iter")

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())

@gaurav_verma i tried the same.

i have written a function which get the lun info for specified "serial-number".

it is working fine, but when i tried to fetch multiple lun-info in multi-threaded environment. some threads are successful to fetch info. while some fail with the error i mention:

i have specified the on-tap version also: server = NaServer(ip, 1 , 32)

<snip>

def get_lun_by_serial_no(self, serial_no😞

try:

api = NaElement("lun-get-iter")

xi = NaElement("desired-attributes")

api.child_add(xi)

xi1 = NaElement("lun-info")

xi.child_add(xi1)

xi1.child_add_string("path","<path>")

xi1.child_add_string("serial-number","<serial-number>")

xi1.child_add_string("volume","<volume>")

xi1.child_add_string("size","<size>")

xi1.child_add_string("vserver","<vserver>")

xi1.child_add_string("uuid","<uuid>")

xi2 = NaElement("query")

api.child_add(xi2)

xi3 = NaElement("lun-info")

xi2.child_add(xi3)

xi3.child_add_string("serial-number",serial_no)

xo = self.serverobj.invoke_elem(api)

xmldata = xo.sprintf()

data = self.get_xml_to_dict_data(xmldata)

if (xo.results_status() == "failed") :

message = self.client_conn.format_exception(data)

raise Exception(message)

if data.get('num-records') != '0':

return data["attributes-list"]["lun-info"]

return []

except Exception as e:

message = "lib Fail to get luns: " + e

raise Exception(message)

Error:
