I think you can, you just need to declare the environment for each driver and that's all. Have you tested it?
Comment 2 Rajini Karthik 2017-04-24 18:26:18 UTC 
Can you have multiple of the same backend? Like multiple PS series , Multiple SC series or multiple Ceph? And any combination of all

Comment 3 Paul Grist 2017-05-03 13:25:58 UTC 
This one looks more like a question than a bug. Has this been tested, it sounds like it should work even upstream.

Comment 5 Rajini Karthik 2017-05-03 14:53:49 UTC 
I have attached a sample environments file that worked prior to compo sable roles and services uses multiple Eqlx backends. Will the same work now?
Comment 6 Paul Grist 2017-05-03 20:48:50 UTC 
Thanks, let's see if Alan can answer based on the recent fixes for those.

Yes, it will work the same (I verified). You can still use an environment file to declare multiple "user enabled" back ends. The syntax is unaffected by the transition to composable roles.

Unless I misunderstand the initial concern, I think this can be closed WORKSFORME.
