Trying to configure iSCSI multipath

Have you opened MPIO in windows, switched to the discovery multi-paths tab, checked the "Add support for iSCSI devices" box, added it, hit ok and rebooted the server yet? Regarding the access control list, you should always use the access control list since it's the only way different initiators are aware of eachother when connected to the target. If you didn't have access control enabled and had 2 clients connect and start manipulating data(since it's treated as a block level device, not a normal network file access protocol) it's a very quick way to end up with corrupt data.

You probably didn't read the post above. I usually setup MPIO on dozen of servers based on 2008R2, so I have a pretty much precise idea on the way to perform it.
I asked for the device ids, but seems noone knows what I'm talking about. Reading the docs I linked is useful, really.
And yes, I know what is an iSCSI disk and the problems of parallel accessing them.

So back to my question: which device IDs does this device exposes? And are you sure it supports MPIO besides MCS? Are you able to point at some kind of documentation?

For the records: using MCS (round robin and weighted paths) the ReadyNAS badly crashes after 10 minutes of DPM writing on it at 90 Mb/sec (not that much indeed).
Is there anyone using PRO6 and DPM that completes a backup? I'm stuck with PRO6 not responding to ping probes on any interface...

p.s.
And yes, I rebooted lots of times, each one after adding new device ids to MPIO.
