  • Migrate a volume with back-end assistance.

  • Retype a volume.

  • Manage and unmanage a volume.

When you use back-end assisted volume migration, both source and destination clusters must be in the same HP LeftHand/StoreVirtual management group. The HP LeftHand/StoreVirtual array will use native LeftHand APIs to migrate the volume. The volume cannot be attached or have snapshots to migrate.

Volume type support for the driver includes the ability to set the following capabilities in the OpenStack Cinder API cinder.api.contrib.types_extra_specs volume type extra specs extension module.

  • hplh:provisioning

  • hplh:ao

  • hplh:data_pl

To work with the default filter scheduler, the key-value pairs are case-sensitive and scoped with 'hplh:'. For information about how to set the key-value pairs and associate them with a volume type, run the following command:

 $ cinder help type-key
