Note: The above event message has no functionality or performance impact on the client systems. This event provides a warning that multiple disks on the system shared the same identification information (like serial number, page 83 IDs etc.)
- If multiple paths to the same physical disk device are available, but Microsoft Multipath I/O (MPIO) is not enabled, the device is exposed to the system by all paths that are available. This causes the same device ID data (such as Device Serial Number, Vendor ID, Product ID, and so on) to be exposed multiple times.
- If Virtual Hard Disks (VHD) are duplicated by using a copy-and-paste operation to create additional virtual machines (VMs), none of the internal data structures are changed. Therefore, the VMs have the same disk GUIDs and the same ID information (such as Device Serial Number, Vendor ID, Product ID, and so on).
