Update volume attachment

Edit online

IBM® Power® Virtualization Center has extended the functionality of the PUT /v2.1/{tenant_id}/servers/{server_id}/os-volume_attachments/{volume_id} which allows you to set the delete_on_termination attribute of volume attachments. This enables you to control whether a volume will be deleted when the associated virtual machine is deleted.

Note:

This functionality is available only with the Nova 2.22 microversion.
PowerVC does not support swapping volumes.
