Not an answer to your question, but be careful, DSS v6 failover cluster has issues with Hyper-V failover cluster yet (BSOD of VMs when doing iSCSI failover on DSS). At the moment you must put your VMs to saved state before you can failover on DSS. I hope open-e is working on that problem ...
BTW: We use also Areca controller which works well with DSS.

DSS v6 b4550 iSCSI autofailover with Windows 2008 R2 failover cluster (having still some issues with autofailover).
2 DSS: 3HE Supermicro X7DBE BIOS 2.1a, Areca ARC-1261ML FW 1.48, 8x WD RE3 1TB, 1x Intel PRO1000MT Dualport, 1x Intel PRO1000PT Dualport.
2 Windows Nodes: Intel SR1500 + Intel SR1560, Dual XEON E54xx, 32 GB RAM, 6 NICs. Windows Server 2008 R2.

pfeifferl, you meant if the primary DSS is turned off, all the VMs will go into BSOD when the secondary DSS is taking over the job?Originally Posted by pfeifferl

During the failover/failback there is a short outage in iSCSI connection. There are lots of error events in Windows event log (e.g. "Initiator failed to connect to the target." ...) on cluster nodes and the cluster disks are going offline and online again. Only a few seconds, but the VMs running on cluster (with CSV) are crashing a few seconds after that occures.
I've opened a trouble ticket at open-e support, but no answer yet ...
So my workaround is to save the VMs, doing the DSS failover and start the VMs again. It's bad for a HA scenario, but the only way at the moment ...

You're using Supermicro + Areca, not sure if it's related, but mine is Dell R710 + Adaptec 5805Z. I will try out the fail over sometime and let you know if it would also crash all the VMs due to lost in iSCSI connection. I will need sometime....
What you mentioned is not a workaround.....if your primary DSS fail, that's it. Are you running any SCOM + SCVMM to auto reboot all the VM when the secondary DSS takes over successfully?
