WFA 2.1+ CM Snapshot support with Unified Manager 6.0+

Question

Hi All,
If you've come here, you may have noticed that WFA 2.1 appears to lack support of Snapshots in cDOT, and the Snapshot database view within OnCommand Unified Manager 6.0 and above is empty.
This pack intends to fill that gap by providing a separate collector that uses the same list of clusters as the Unified Manager database collector, but goes directly to the cluster to gather Snapshot information. In future it may gather other information not available within a Unified Manager view.
Updates included in v4:
Includes Cluster and Vserver Peer information collections, dictionary, commands and filters.
You can also connect directly to the cluster, no Unified Manager required!
To connect directly to a cluster, specify a comma separated list of clusters to connect to, using their 'primary_address' as registered in OnCommand Unified Manager to ensure filters match the cluster.primary_address field.
Here is an overview of the components in the attached.
Schema: cm_storage_augment
Dictionary:
Snapshot          Represents a Volume Snapshot
Vserver_Peer    Represents a Vserver Peer relationship
Cluster_Peer     Represents a Cluster Peer relationship
Commands:
Create Volume Snapshot             Creates a Volume Snapshot
Remove Volume Snapshot           Removes a Volume Snapshot
Create Storage Virtual Machine Peer with reservations
                                                 Creates a Vserver peer including cm_storage_augment reservations
Create cluster peer with reservations
                                                 Creates a Cluster peer including cm_storage_augment reservations
Note: These commands do not depend on the cm_storage_augment schema and may be used independently if needed.
DataSource:
CM Storage Augment_6.0           Collects Snapshot information from OnCommand Unified Manager 6.0 and above (via direct cluster connection)
Filter:
Snapshots by Volume                 Returns a list of Snapshots for the specified volume
Snapshots by Volume Regex       Returns a list of Snapshots matching a regex for the volume (ie. ^hourly)
Clusters with Available Peer Relationships (includes self)
                                                  Returns a list of clusters that have an existing cluster peer, suitable for use in determining where Vserver Peering is possible.
Filter Aggregates available through Cluster Peers
                                                  Returns a list of aggregates available on clusters that are peered
Filter Aggregates available through Vserver Peers
                                                 Returns a list of aggregates available on clusters and vservers that are peered matching a regex. Useful in determining if a similar named Vserver exists on the destination.
Workflow-Example: Create Snapshot
               Creates a Snapshot of the selected Volume.
Workflow-Example: Remove Snapshot
               Removes a Snapshot of the selected Volume.
Installation Steps:
        Import the DAR file (attached)
        On the Credentials tab, ensure each cluster that is configured in OnCommand Unified Manager is listed and has correct credentials.
        Select the Data Sources tab. Create a new Data Source of type "CM Storage Augment - 6.0"
        Enter details of the OnCommand Unified Manager server and user account
          (User credentials must be normal users and NOT database users)
        Ensure you select "cm_storage_augment" and "Reset Schema" to create database tables.
Note: Reservations have now been included! Snapshot timestamp is set to 'now' so may adjust once a collection cycle has completed.
          Release v3 include Congruence Tests and Reservation Strings to complete the reservations information. It is also marked as PS Certified to indicate reservations are present.
           If using v2, ensure you update or reservations will not behave as expected.
           If upgrading to v4, ensure you select "Reset Schema" to allow the new Vserver and Cluster Peer tables to be created before the next collection.
Please report any feedback to [email protected], thanks!
Enjoy!

Hello, I had no issue importing the dar file but am having one getting the cluster setup as the data source.  Credentials have been set and tested successfully, an OCUM data source was previously setup and tested successfully, but the cluster data source fails with the following error in the wfa.log: failed: com.netapp.wfa.cache.execution.CacheException: Error running data acquisition script: At C:\Program Files\NetApp\WFA\jboss\standalone\tmp\wfa\cm_storage_augment4582972690885238274.ps1:172 char:43 WFA version 2.2 GAWindows 2008 R2 EE (new vm)PowerShell 3.0.NET 4.5OCUM 6.1cDOT 8.2.1p1IE8 and FF32 Has anyone seen this or have an idea on how to fix it? Thanks.
