I am trying to to explorer automating our Commcell environment. Unfortunately I encountered and error connecting to commcell. I would like to inquiry the error when connecting to commserve using cvpysdk python library. Below is the error. 



Error when connecting to commserv using hostname. but i can ping the hostname from the server.



If something is blocking, is there a required port to open to be able to connect successfully?

>>Use the Python SDK to run Commvault operations in your CommCell environment. The Python SDK requires an installation of the Web Console.​

Step 1: Install the Python SDK​

​Step 2: Install the Python Software​

​Windows and UNIX​

​If you installed the Python SDK on a Windows computer or a UNIX computer, no action is required. Python 3.6 is automatically installed along with the Python SDK.​

On a Windows computer, the installation location is C:\Program Files\Python36. On a UNIX computer, the software is packaged inside the Commvault installation directory: %INSTALL_PATH%/python/bin/python3 (for example: /opt/commvault/python/bin/python3).​

Step:3 Establish a Connection​

>>Applies to: Windows and UNIX clients​

​Import the Commcell class and log on to the CommCell environment. The following is the Python commandlet for establishing a connection:​

>>> from cvpysdk.commcell import Commcell​

>>> commcell = Commcell(webconsole_hostname, commcell_username, commcell_password) ​


webconsole_hostname is the host name and port number for the Web Console.​

commcell_username is the user name used to log on to the CommCell environment.​

commcell_password is the user password in plain text. If you do not provide the password in the command, you are prompted to enter the password at run time.​

​Step 4: Where to Go From Here​

​Run Commvault operations through the Python SDK or incorporate the Commvault Python commands into scripts or other code.

For sample you can follow the below DOC:

Hi Navneet,


Thanks for your time. What i did is the same from what you have provided below and that error I encountered is not able to connect to Commcell when running the python lines the same with you provided.



Hoping you if you could check further my concern.

We need to review the configuration and logs. You can raise a support case to check this.
