Mpio warnings and error on HYPER-V cluster

Hello !

We have 4 nodes HYPER-V cluster, which runs on HP ProLiant BL460c servers (each server has HP FlexFabric 10Gb 554FLB 2-port adapter)), connected to HP 3Par StoreServ 7200 disk through the HP FlexFabric 10 Gb/24-Port module. The cluster works well, but one day we found that every 20-30 minute in the system event log on each node start to display error, warning and information events from MPIO source (Event IDs 2, 17,46):

********************************************************************************************

The description for Event ID 46 from source mpio cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

\Device\MPIODisk15
77010001

The description for Event ID 17 from source mpio cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

\Device\MPIODisk13

Please give an advice how to fix these events. What should we check first: hyper-v or shared storage?

Thanks in advance,

Max
