DECO: docker volume ls not working.

[sandesh-desai]

Steps to re-produce:

1. docker volume create -d hpe --name Merlin_Volume14 -o backend=Merlin
2. docker volume inspect Merlin_Volume14
3. docker volume ls

Expected result:It should show volume name as Merlin_Volume14
Actual result: It shows blank.

Below hpe.conf details:

This was due to the failure in initializing the default backend. And the failure was due to incorrect password provided for the array. Please always check the default backend status when you don't get anything displayed in the ls command after creating volume(s). Once the backend is initialized properly, ls should work.

I'm marking this as a documentation issue unless proper backend initialization doesn't resolve it.
