Data ONTAP: Trigger vFiler Discovery Rule

DataONTAP.TriggeredvFilerDeepDiscovery.Rule (Rule)

Knowledge Base article:

Summary

This is the discovery rule for vFilers that are hosted by Data ONTAP storage systems. After valid credentials are provided, this rule contacts each vFiler and discovers all of its logical storage elements.

You must have entered credentials using the System Center Operations Manager console action "Manage Data ONTAP Controller Credentials" before this rule can successfully query the vFilers. The credentials should be those that were setup for this vFiler, not credentials from the hosting storage system.

Configuration

You must setup the proper credentials for the vFiler. Go to "Manage Data ONTAP Controller Credentials” to enter the valid vFiler credentials to the System Center Operations Manager.

Resolutions

If you suspect a problem with this rule, check the OnCommand and System Center Operations Manager event logs on the management server running the rule.
