Comment 5 for bug 1403902

I think this bug should be fixed in one of ways:
- either code should be changed to make 'cider migrate' accept what 'cinder service-list' provides;
- or 'cinder service-list' should include #xxx pool part in its output;
- or documentation should be changed accordingly to allow user to determine how to migrate volumes.

Otherwise in current state I (with user hat on) can't possibly migrate volumes without looking into debug logs and code with pdb. This makes this bug valid.
