Cinder configuration for Block Storage (IBM Storwize v7000)

Hi, I have deployed multinode Openstack using Kolla Ansible. Now, I needed to enable Cinder so that I can make use of the Block Storage. I am connected to my SAN which has IBM Storage v7000 working as Storage Backend. Steps I performed: 1. Enable Cinder in globals.yml on the deployment node. 2. Created a Physical Volume and then a volume group "cinder-volumes" on my Compute node, following this guide: https://docs.openstack.org/mitaka/install-guide-rdo/cinder-storage-install.html (https://docs.openstack.org/mitaka/ins...) 3. Re-deployed Openstack 4. Cinder was installed. I can now see "Volumes" in my Horizon Dashboard. 5. Now, I wanted to make use of the IBM Storwize Drivers. So I edited the cinder.conf file and made the following entries:

enable_backends=storwize_svc_driver


[storwize-svc-driver]

volume_driver = cinder.volume.drivers.ibm.storwize_svc.storwize_svc_fc.StorwizeSVCFCDriver

san_ip = x.x.x.x

san_login = username

san_password = pass

storwize_svc_volpool_name = pool_name

volume_backend_name = storwize
  1. I restarted my Cinder Container.

Now, I expected that I would be able to make use of the Storwize Driver but seems like I am still using the default LVM. The changes were not reflected (Horizon still shows Volume host as LVM)

Please let me know what I am doing wrong.

Thanks, Rohit

I found out the solution by doing r&d. Thanks anyway.

It was a silly mistake enable_backends should be enabled_backends.. argh...
