Server 2012 Virtual DC hosted on Physical Hyper-V hangs overnight

HP Recommended

I have a DC that is hosted on a physical Hyper-V server, both running Server 2012.  It seems that overnight going into the morning the DC hangs up causing users not to be able to log in.  I was able to remote into the Hyper-V server and look at the console.  There's also an Exchange and SQL server which respond fine.

 

I could get to the DC login screen but couldn't do anything from there.  Ctrl Alt Del worked on both other servers, but not the DC.  I also couldn't shutdown the DC vm but I could turn it off.  After turning it off it resolved the issues of it being unresponsive.  All services resumed and I was able to log into the DC and things appear normal.  The only errors in the Event Viewer are related to the services stopping.

 

All servers are hosted on pass through disks, rather than partioned on the Hyper-V physical disks.

 

Combing through the errors on the Hyper-V server doesn't give too much, aside from around 3am the netlogon errors occurred and 5am these occurred:

 

Event ID 129 Source HpCISSs3

 

Reset to device, \Device\RaidPort0, was issued.

---------------------------------------------------

Event ID 5008 Source HpCISSs3

 

On controller (bus 2, device 0, function 0) the OS requested a Reset of LUN (0, 1, 1).

---------------------------------------------------

Event ID 153 Source disk

 

The IO operation at logical block address 0x158c5a0 for Disk 1 was retried.

 

I appreciate any help!
