error: Failed to connect to cluster node

Anyone ever get this?  Connectivity if fine with other work flows and when I test the connection via WFA it if fine.

Here is the ouput from the logs:

Thanks.

Hi,

Have you added the credentials for the host : bbcs1va2.blackboard.com, in the WFA (Execution->Credentials page).!

If you have added it, can you please try to test the connectivity for this host by using Test Connectivity option in the Credentials page by providing the host name(bbcs1va2.blackboard.com), you can do this by right clicking on that page,( I guess you are still using pre-2.1 build,where you don't find any tool kit icons on the top of the page)..!

In generally we get the below log message when we don't have the entry in Credentials page for that particular host.

16:26:07.712 INFO [Create CM Qtree Quota] Connect-NcController (without credentials) -Name bbcs1va2.blackboard.com

Credentials are fine.  I have already tested them with the method you speak, and other workflows are working, so it is not a communication problem or a credential problem per se:

Hi, we experience exactly same problem. Did you find any solution?

We figured out that it only happen on newly created SVM.

The diffenrence in the log shows that SVM1 and SVM2 uses an IP address while SVM3 (the problematic one) uses the the hostname (not FQN).

It would be nice if there was a feature in WFA to tune connection retries and as well as connection timeout values.

This doesn't need a feature. This is already possible to have  connection retires and timeout as parameters into command code. Just modify your code accordingly.

Have you been able to resolve your issue?

This is true, except that certified commands can't be modified, so they'd need to be cloned, then tuned AFAIK. We have a few CDOT clusters located in multiple geographies which sometimes have minor connectivity issues with WFA.

@jauling_chou

A certified command covers the most common generic use cases to fulfill the most common requirements. User specific requirements will always have to be fulfilled by creating custom contents and cloning of a certified command and then modifying makes it so much easier than starting from zero. 

There is functionally NO differnce between a certified command and a custom command. But if you need certification and support, NetApp professional services is the option for you.

I understand this, but this problem needs to be dealt at the command code and not by having new a WFA feature.
