manage_existing(volume, existing_ref)

Manage an existing non-openstack DotHill volume

existing_ref is a dictionary of the form: {‘source-name’: <name of the existing DotHill volume>}

manage_existing_get_size(volume, existing_ref)

Return size of volume to be managed by manage_existing.

existing_ref is a dictionary of the form: {‘source-name’: <name of the volume>}

map_volume(volume, connector, connector_element)
migrate_volume(volume, host)

Migrate directly if source and dest are managed by same storage.

Parameters:
  • volume – A dictionary describing the volume to migrate
  • host – A dictionary describing the host to migrate to, where host[‘host’] is its name, and host[‘capabilities’] is a dictionary of its reported capabilities.
Returns:

(False, None) if the driver does not support migration, (True, None) if successful
