We have exactly the same issue as the users above.

Environment:

Dell 2950 v3 with Open-E v6 latest build
Dell 2950 v3 VMware Hosts with VMware vSphere 4.1i Enterprise


Usage of a Raw Device Mapping hangs the VM that has the RDM attached. (virtual and physical rdm same issue)

Rebooting the VMware host releases the lock and another power on of the VM with the RDM makes the VM hang again.

When we're using the same volume and format it as a VMFS-3 volume no problems exist at all.

Some help from open-e would be appreciated.

Thanks in advance
