could not login to UCS manager sandbox using UCS Python SDK

a11024 — Fri, 30 Apr 2021 11:08:21 GMT

[1] I was able to SSH to 10.10.20.110 and 10.10.20.113 (the 2 UCS manager sandbox IP addresses) via Cisco AnyConnect.

[2] But the following python script does not work.

from ucsmsdk.ucshandle import UcsHandle
HANDLE = UcsHandle("10.10.20.110", "ucspe", "ucspe") or
HANDLE = UcsHandle("10.10.20.110", "admin", "ciscopsdt")

# Login into Cisco UCS Manager
HANDLE.login()

the error message is

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\david.smith\AppData\Local\Programs\Python\Python39\lib\site-packages\ucsmsdk\ucshandle.py", line 135, in login

response = self.post_elem(elem, timeout=timeout)

child_elems = elem.getchildren()
AttributeError: 'xml.etree.ElementTree.Element' object has no attribute 'getchildren'

Anyone knows why?

thanks

Hello, this isn't a fault with the sandbox, this looks like the version of python you are using is not supported (Python 3.9 incompatibilities). I would suggest, trying this with another Python (3.4 is listed as working) version or creating an issue on the repo https://github.com/CiscoUcs/ucsm_apis - I see there is further support via a slack room, details are here https://pypi.org/project/ucsmsdk/

Hope this helps.

Thanks @bigevilbeard:

I uninstalled Python 3.9.4 and installed 3.7.3 and the same script worked on 3.7.3

You can close the case. Thanks for help.

Sincerely,

Patrick
