Bug 1342652

Created attachment 1164624 [details]
Patch that apply the changes to kilo version of tripleo-heat-templates.

Description of problem:
When configuring cinder-backend, such a HP3Par or EMC VNX, this can be done by using the cinder_config class in cinder puppet module.

=== Storage Environment YAML example:
-------------------------------------------------------------------------
parameters:

  #### BACKEND SELECTION ####

  ## Whether to enable iscsi backend for Cinder.
  CinderEnableIscsiBackend: false
  ## Whether to enable rbd (Ceph) backend for Cinder.
  CinderEnableRbdBackend: false
  ## Whether to enable NFS backend for Cinder.
  CinderEnableNfsBackend: false
  ## Whether to enable rbd (Ceph) backend for Nova ephemeral storage.
  NovaEnableRbdBackend: false
  ## Glance backend can be either 'rbd' (Ceph), 'swift' or 'file'.
  GlanceBackend: file

parameter_defaults:
  ExtraConfig:
    cinder::config::cinder_config:
      3par01/volume_driver:
        value: cinder.volume.drivers.san.hp.hp_3par_fc.HP3PARFCDriver
      3par01/volume_backend_name:
        value: 3par_FC
      3par01/hp3par_api_url: 
        value: https://192.168.100.10:8080/api/v1
      3par01/hp3par_username:
        value: username
      3par01/hp3par_password:
        value: password
      3par01/hp3par_cpg:
        value: OSP7
      3par01/san_ip:
        value: 192.168.100.10
      3par01/san_login:
        value: username
      3par01/san_password:
        value: password
    cinder_user_enabled_backends: ['3par01']
-------------------------------------------------------------------------



In OSP-7 tripleo-templates the 'cinder_user_enabled_backends' the missing pice to make this work.

Request to bacport the following:
http://git.openstack.org/cgit/openstack/tripleo-heat-templates/commit/?id=31c91bed886f76e107a78021977e4c9bd338c76a


Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-0.8.6-123.el7ost.noarch

How reproducible:
Easy

Steps to Reproduce:
1. Add Storage Environment YAML with content of example above.
2. Deploy
3. ssh -l heat-admin <overcloud-controller-ip> 'sudo grep enabled_backends /etc/cinder/cinder.conf'


Actual results:
#enabled_backends=<None>
enabled_backends=

Expected results:
#enabled_backends=<None>
enabled_backends=3par01

Additional info:
The attached patch is a modified version of the upstream patch that will apply cleanly to the kilo tripleo-heat-templates.
