I am in the midst of upgrading my failover cluster servers to WS2012. I created a new cluster and I am migrating my VMs into it. Most VMs are working fine in the new cluster, but I am having trouble with one VM which has some passthrough disks attached to it, which are connected to an iSCSI SAN. The host connects to the SAN, and the disks are connected to the VM in Hyper-V settings.
I got that VM running on one of the WS2012 cluster servers, but when I try to add it into the cluster, I have trouble with the attached disks. I tried adding the disks to the cluster before adding the VM to the cluster. I also tried not adding the disks to the cluster. I tried attaching them to the VM before and after adding the VM to the cluster. I can’t seem to get it to work no matter which way I do it.
In most cases, the VM fails to start with the following error:
'Virtual Machine DB1' failed to start.
'DB1' failed to start. (Virtual machine ID 11B3CCBE-0F7F-4774-8156-810E969D1954)
'DB1' Synthetic SCSI Controller (Instance ID 6F38B394-4E10-4CB9-BFA9-A22A970F8BCC): Failed to Power on with Error 'General access denied error' (0x80070005). (Virtual machine ID 11B3CCBE-0F7F-4774-8156-810E969D1954)

Error: 'General access denied error' (0x80070005). (Virtual machine ID 11B3CCBE-0F7F-4774-8156-810E969D1954)
Under WS2008R2, I was able to use this procedure to set it up.
But as WS2012 does not have a “refresh virtual machine config” feature, I cannot use the same procedure.
Does anyone know what the procedure is in WS2012?
