Error running the command "Add Volume to Dataset"

[Aravind]

I am trying to the use the command "Add Volume to Dataset" in my workflow,when i test the command i am getting the below mentioned error

"No connection could be made because the target machine actively refused it"

is there anything which needs to be configured on the dfm server before running this command.As this command tries to establish a SSH session with the dfm server.

the powershel cmdlet used in this command is Invoke-NaSSH,

Any guidance on this would help.

Do you have any SSH server running on your DFM?

Using Putty or any other SSH client, try to connect via SSH using the credentials you providing in WFA.

As of now there is no SSH server configured on the dfm server. Is SSH Server instaltion required to run this particular command.Or is there any other alternative way.

If you have no money in your bank account, can you find an alternative way to draw some money using your ATM card?

Think again..

Hi,

It's possible to use the DFM API rather than rely on the WFA certified command which uses the "Invoke-NaSsh" CmdLet.

If you use the DFM API method below you don't need to install SSH on your DFM server.

Here is the PowerShell Code. Hope this helps?

Cheers

Thanks a lot matt, that worked for me.
