Title:
  ScaleIO Volumes Created before Newton, do not connect or disconnect
  after Newton upgrade

Status in OpenStack Compute (nova):
  Invalid
Status in os-brick:
  New

Bug description:
  Description
  ===========
  ScaleIO volumes that were created pre stable/newton ( stable/mitaka ) in my case, 
  do not connect or disconnect to/from the hypervisor when nova-compute attempts the 
  connection after the upgrade to stable/newton.

  This appears to be because the os_brick 1.2 to 1.6 change includes a new attribute 
  'scaleIO_volume_id'
  This field is not created if the volumes were created at stable/mitaka or before.
  In this case, this field is not found in nova.block_device_mappings 'connection_info'
  column. This field is created for volumes created after stable/newton upgrade.

  
  Steps to reproduce
  ==================
  1. Install ScaleIO
  2. Install openstack via openstack-ansible stable/mitaka
  3. Create and connect ScaleIO volumes to instances
  4. Upgrade to stable/newton
  5. Shutdown a instance
  6. Attempt start of a instance

  Expected result
  ===============
  The instance should start

  Actual result
  =============
  The instance would not start.

  --after manually adding the 'scaleIO_volume_if' parameter to 
  nova.block_device_mapping.connection_info the connect / disconnect
  works as expected.

  Environment
  ===========
  1. Exact version of OpenStack you are running. See the following
    stable/newton deployed via openstack-ansible 14.0.3

  2. Which hypervisor did you use?
     libvirt+kvm

  2. Which storage type did you use?
     scaleIO 2.0.1

  3. Which networking type did you use?
     neutron with linux bridge

  Logs & Configs
  ==============
  http://pastebin.com/Pvd6HrcL

  os_brick version with OSA stable/mitaka = 1.2
  os_brick version with OSA stable/newton = 1.6
