Message

Unexpected failure. Error code: 490@01010004

 

Cause

The Virtual Disk Service (VDS) looks for the Location paths property of the controller. The value of this property is the path location of the disk. However, a virtual controller does not have this property.  This can happen when:

  • You have a Hyper-V guest operating system that is running Windows
    Server 2008 R2 or Windows 7.
  • The guest operating system has a disk that is connected to a SCSI controller.

User Action
None required. This event can be safely ignored.
