Hello,

I was wondering if anyone already tried to combine  EV Clustering (on Microsoft) with EV Building Blocks for DR? :

Primary site: Virtual EV server 1 on Microsoft cluster. This EV is doing all the work.
DR site: Virtual EV server 2 on Microsoft cluster. In case of DR, we would like to do 'Update Service Location' to switch EV services to Virtual EV server 2.

Between Primary and DR site we have I/O synchronization with EMC SRDF.

I did a test in my lab with a Primary EV cluster, and DR EV standalone which seemed to work (USL ok).
But now with one cluster at each side, the 'Update Service Locations' seems to hang completely (it gets stuck on 'Checking Task Controller Service'') when I run it the first time.

I know that USL and cluster are probably mutually exclusive solutions, but it does not say so explicitly in the docs and my partial test was successful.

Thanks for any commens and insights,

Francis
