Re: Unable to add Storage Controller - Connection failure

Is having OnCommand Unified Manager or Vsphere as a data Acquisition unit mandatory for WFA to work? i'm unable to execute any workflows. By default the Workflow is executing on aggr0 which is the default Boot volume.Can anyone help, Please send me any good documents where i can start testing on WFA Workflows.Thanks

Re: Unable to add Storage Controller - Connection failure

Mahesh,

You have mentioned quite a few points, i will address them individually:

  • "Is having OnCommand Unified Manager or Vsphere as a data Acquisition unit mandatory for WFA to work"

         It is not mandatory to have a data acquisition unit (data source) for WFA to work(implying workflow execution). In this case, the user has to define all the       objects required by the corresponding  workflow to execute.

         Having said that,it is recommended to add data sources to facilitate object selection (based on intelligent criteria defined in the filter/finder used) during workflow execution. This removes the overhead on the user to explicitly define the objects in the workflow.

  • "i'm unable to execute any workflows"

         Can you be more specific here?

         Have your workflow executions resulted in errors? If yes,please mention them.

  • "By default the Workflow is executing on aggr0 which is the default Boot volume"

         Which is the workflow that you are referring to? What is the point of contention here?

  • "Please send me any good documents where i can start testing on WFA Workflows"

         A good document to start would be the "OnCommand Workflow Automation Installation and Setup Guide"  that can be picked up from the NetApp Support site.

       There are some really good related videos on the community. A couple of them(Courtesy : Kevin Hill) more relevant to you :

      1. Building your first workflow
      2. Workflow Automation Technical Introduction

       NOTE : Both these videos are part of a larger training series : WFA How-To Video Series

Re: Unable to add Storage Controller - Connection failure

Thanks For your Quick reply,

      1.  when i'm executing a workflow this is what i'm getting

2. When i tried using filters to get all the aggregates in the Array by IP:

This is what i got, it was showing no aggregates in the array.But when i check through Putty:

This is what it shows....

and ya Thanks for the Videos....

Re: Unable to add Storage Controller - Connection failure

Hi Mahesh,

The error you are receiving states your issue on the second line "No Results were found".

This is where the sample workflow you are executing is trying to be intelligent about the placement of your new volume & share. This is where datasources are used.  WFA will acquire information about your storage controllers by collecting that information from Unified Manager.  Without it, it is still possible to update the workflow where you have to put in all if the information via user inputs.

Tanzim is correct that technically it is possible to run WFA without datasources.  However, it is unadvisable to do so.  Is there a specific reason you are not using Unified Manager in your environment?  You will have a much better experience with WFA if you start using Unified Manager as a datasource.

Best,

Kevin

Re: Unable to add Storage Controller - Connection failure

Hello Mahesh,

To add to what Tanzim said:

There is no required data source and WFA can work with out it. With that said, the resource selection mechanism (Using finders) will not work without data sources.
It is highly recommended at least to have one OCUM as a data source, as it would give you most of the needed info on NetApp storage it monitors.

Regarding workflows not executing due to using mostly aggr0:

Some of our certified finders exclude aggr0 in their search for a valid aggregate. If you mostly use those, it might be good for you to select the filters that you want ad hoc and save them as a finder of your own.
That would make sure that aggr0 would be a valid option (Obviously if you won't select that "Aggregate is not aggr0" filter for your finder :-))
