Had my first run in with powershell cmdlts and vfilers, it panic'd a box. Here is the details from NetApp.
Is there anything that can be done powershell side without having to go to a GA release?
Problem Summary:
The Multistore feature of Data ONTAP provides logical "vfiler" entities, each of which encapsulates a set of storage resources. When an external management agent wants to interrogate Data ONTAP about the operations of a vfiler, it sends an ONTAPI-protocol message over the network to the physical storage controller, which interprets the message and internally dispatches the query or command to the correct logical vfiler.
The username associated with the message may be mishandled, and a null username is passed to the vfiler. The missing data triggers an illegal address fault and causes an interruption of service.
Recommended Solution:
Bug 419019 is fixed. Data ONTAP 7.3.5RC1 (First Fixed) - Fixed
or Data ONTAP 7.3.5.1 (GA) - Fixed
Workaround:
A customer can avoid the panic by preventing external management agents from querying vfiler-specific resources.
