Current 3PAR python module does not seem to be compatible with Alletra MP.

[karthikvr1]

We have tested few functionalities with Alletra 9k, but the same is not appearing to be compatible with Alletra MP. It failed from the authentication itself.

Here are the tests and observations:

1. Tried generating alletra_mp client object via attached python script. Got error about an invalid session_key. Attached snapshot for quick reference.
   alletra_mp_auth.py.txt
   

2. curl POST requests to WSAPI end points are successful for both Alletra MP and Alletra 9k. Sample run command as below.
   $ curl -X POST https://10.XX.XX.53:443/api/v1/credentials -k --insecure -H "Content-Type: application/json" -d '{"user": "storage_admin", "password": "storage_password"}' -L | python3 -m json.tool

Module versions:
hpe3par-sdk == 1.2.2
python-3parclient == 4.2.14

Can you kindly confirm if the 3PAR python module is tested for Alletra MP or there is another module in development for the same.

We are ready to have quick walk through session of the above if required. Also let us know if we are missing anything. Thanks in advance.

It looks like Alletra MP requires authentication on the WSAPI version endpoint whereas the others don't.

Unfortunately it doesn't appear the latest version and documentation is updated here on Github.

Based on OpenStack documentation, it would appear the minimum release of python-3parclient with Alletra MP B10000 support is version 4.2.14, which is the latest currently available from PyPI specifically:
