Seems to be a long thread on this here: http://social.technet.microsoft.com/Forums/windowsserver/en-US/e95631c6-c6b0-4dc8-a003-af4adbf113e9/windows-server-2012-can-occasionally-not-access-second-virtual-hard-drive-inside-a-vm?forum=winserverhyperv
(lots of people with file servers commenting). Seems to be an issue logged when you have a disk connected to the virtual SCSI adapter, however the issue also occurs when connected to the IDE adapter (but isn't logged). I'd suggest opening a case with PSS (if the problem persists after updating any relevant drivers etc). In the interim, you could try disabling VSS snapshots on the host volume (if you don't need them) Cheers Ken From: [email protected] [mailto:[email protected]] On Behalf Of J- P Sent: Wednesday, 8 January 2014 10:53 AM To: [email protected] Subject: RE: [NTSysADM] event 129 on 2012 hyper-V guest only one of the 5 guest are exhibiting this that is why i didn't think hardware (not at the disk level at least) I wouldnt mind calling PSS but I'd hate to hear "its the hardware not the os" Jean-Paul Natola ________________________________ From: [email protected]<mailto:[email protected]> To: [email protected]<mailto:[email protected]> Subject: RE: [NTSysADM] event 129 on 2012 hyper-V guest Date: Tue, 7 Jan 2014 23:39:01 +0000 The blog poster is seeing the event on a host server, not a guest. You are seeing this event on a guest? And you are not seeing anything on the host?

I have applied this change http://blogs.technet.com/b/kevinholman/archive/2013/06/21/event-id-129-storachi-reset-to-device-device-raidport0-was-issued.aspx this step What finally resolved this for me - was changing the power management settings, from Balanced to High Performance. What this actually changed that was critical to this condition was modifying PCI Express > Link State Power Management > Off hoping it will work, does anyone have any thoughts?
