Hi,
I have been banging my head with few issues for a while, and I hope to get some help here.
I have 2 hyper-v hosts (windows 2012) in a cluster.
both hosts are connected via iscsi to a storage where all the VMs are.
Each one of the hosts have 2 NICs : 1 for iscsi , 1 for connectivity (management and network to VM) , we don't have a huge requirement to add more NICs as the traffic is not bad.
Here are my issues so far and they might be related:
1- Every week I have one of the 2 nodes fails because it disconnects from the storage for some reason, sometimes it fail back to the second node, and sometimes I have to go and start manually all the VMs.
2- When I start the VMs, it's agonizing how slow is the startup process, (it might take between 15 min to 1 hour for a VM to start). After it starts, and I guess it's because it's slow, the network on the VM takes time to start as well, so any network related service on the VM doesn't start (for example MSSQL doesn't start), so I have to go log in to each VM and start the services that didn't start automatically because the network didn't come up fast enough.
3- I used to have live migration working , but since the last failure, live migration doesn't work anymore, I get an error : Failed to live migrate virtual machine 'machine name' For more data, see 'information Details' , and in information details , I get : The action 'Move' did not complete. Error Code: 0x80070057 , the parameter is incorrect.
4- I also noticed in one host an event ID 1196 showing every 15 minutes, details are: Cluster network name resource 'Cluster Name' failed registration of one or more associated DNS name(s) for the following reason: The handle is invalid.
Any help will be much appreciated.
Thank you.
