On a Hyper-V host that is managed by System Center Virtual Machine Manager 2008 (VMM 2008), an event ID 113 or event ID 1 is logged every 30 minutes or more:
Automatic or manual VMM Host refresh can create these events. VMM queries a WMI path during the scan of physical disks which includes iSCSI SAN disks.
WMI path: schemas.microsoft.com/wbem/wsman/1/wmi/root/wmi/MSiSCSIInitiator_MethodClass
Some storage providers have confirmed this event can be seen and reproduced in some configurations when making WMI queries to the above namespace. This specific warning message can be safely ignored.
The symptom might also appears if a manual refresh of the host is initiated from VMM.
During the refresh, VMM is performing a scan for changes on the host machine, checking changes to items such as the following:
• Updates to virtualization host properties and status
• Updates to physical disks and SAN information
• Updates to networking information like physical nics and virtual switches
It is during the scan of physical disks and SAN information that the iSCSI devices are being polled and the above event is logged with a status of 0xefff0003 // ERROR_PATH_NOT_FOUND.
