To monitor storage, you must first run the discovery process in System Center Operations Manager (SCOM).
For the clustered Data ONTAP SCOM management pack, the discovery rules are targeted at a resource pool.
The OnCommand Plug-in for Microsoft discovery and monitoring scripts are called using Windows PowerShell and run under the context of an action account in SCOM. This account should have a Windows profile created to run the PowerShell script. If this account is not used to log in to the SCOM server before running the OnCommand Plug-in for Microsoft SCOM management pack, the discovery and monitoring tasks fail to run the PowerShell script.
