Hi,

Just built a Server 2012 R2 Hyper-V failover cluster connected to Equallogic 4110 storage arrays with latest firmware and HIT kits.
When creating a clone or vm from a template we see that the cluster loses access to the storage csv volume that is hosted on the equallogic storage with the following errors:

Cluster Shared Volume 'Volume1' ('CSV Disk1') has entered a paused state because of '(c0000435)'. All I/O will temporarily be queued until a path to the volume is reestablished.

Full details are below, from reading the Microsoft technet forums this is a known issue with Equallogic hardware provider, can anyone shed any light onto this issue?
