Hi,
In my test/lab I'm working with a single node just for testing functionality... once it works, I will expand this configuration up to 10 nodes.
I'd like all hosts having a drive for live data and the other for DR and backup to tape.
Thanks a lot.

Personally, I didn't quite understand your use-case. You only have a
single host and two drives (one for live data and the other for DR)?
