Hello,
In my company, we encounter some trouble with our actual setup.
Here is our system setup :
- A server Windows 2012 R2
- Hyper-v feature installed
- Around 10 virtual host running on it, server only Windows 2012 R2.
- SAN for storage, lefthand, connected as ISCSI on each virtual host, for adding space storage. SAN and connection are made on a separated network, so 2 network connection per virtual machine, one for production network, the other one for SAN network for the ISCSI connection.
- SAN connection are setup on the Hyper-V host server as a network Team on Windows 2012 r2, setup like the following :
==> 2 Interface on the team
==> Teaming type : Static
==> Load balancing : Hyper-V
On the Hyper-V setup for the virtual network, the interface is create to goes on the team create on windows, and then "Autorize windows to share this network card" is check. This create a windows virtual card for hyper-v, on which one we are assinging the IP address for our private newtork for SAN connection.
Problem is, once or twice per month, the connection fall down, and all our virtual machine lost the SAN connection. The only way to restore it as quick as possible is by doing the following :
- unassign the SAN network on each virtual machine
- Delete the virtual commutator on Hyper-V for SAN.
- Delete the Team on windows
- Create back the Team on windows
- Create back the Virtual Network on Hyper-V
- Assign back the ip address on the virtual interface
- Assign back the virtual newtork on each virtual machine.
Anyone can help us about that problem ?
This is a really big problem for us.
Thank you.
