Been running Server 2012 Hyper-V for a few months now quite reliably. That was until the following event started:
EventId 129 - Reset to device, \DeviceRaidPort0, was issued
When this occurs all VMs become completely unresponsive, cannot even shutdown so need to be forced off.
This particular VM (Server 2012) is using the virtual SCSI device driver with three dynamic .vhdx drives. I have checked the obvious and there is plenty of space for them all to expand into.
Found someone else with the same problem here.
It seems this maybe a (very serious) bug in the Hyper-V virtual SCSI driver.
Has anyone else encountered the same problem?
More importantly any suggested fix for this to get this server back up and running reliably?
This really is a very serious show-stopper, rather a shame because up to then hyper-v 2012 was looking quite good.
