===================================================================
Servers with volume attachments (servers, os-volume\_attachments)
===================================================================
Attaches volumes that are created through the volume API to server
instances. Also, lists volume attachments for a server, shows
details for a volume attachment, and detaches a volume.
List volume attachments for an instance
=======================================
.. rest_method:: GET /servers/{server_id}/os-volume_attachments
List volume attachments for an instance.
Normal response codes: 200
Error response codes: unauthorized(401), forbidden(403), itemNotFound(404)
Request
-------
.. rest_parameters:: parameters.yaml
- server_id: server_id_path
- limit: limit_simple
- offset: offset_simple

- id: attachment_id_required
- serverId: server_id
- volumeId: volumeId_resp
- tag: device_tag_bdm_attachment_resp
- delete_on_termination: delete_on_termination_attachments_resp
**Example List volume attachments for an instance: JSON response**

Attach a volume to an instance
==============================
.. rest_method:: POST /servers/{server_id}/os-volume_attachments
Attach a volume to an instance.
Normal response codes: 200
Error response codes: badRequest(400), unauthorized(401), forbidden(403), itemNotFound(404), conflict(409)
.. note:: From v2.20 attach a volume to an instance in SHELVED or SHELVED_OFFLOADED
state is allowed.
.. note:: From v2.60, attaching a multiattach volume to multiple instances is
supported for instances that are not SHELVED_OFFLOADED. The ability
to actually support a multiattach volume depends on the volume type
and compute hosting the instance.

Update a volume attachment
==========================
.. rest_method:: PUT /servers/{server_id}/os-volume_attachments/{volume_id}
Update a volume attachment.
.. note:: This action only valid when the server is in ACTIVE, PAUSED and RESIZED state,
or a conflict(409) error will be returned.
.. warning:: This API is typically meant to only be used as part of a larger
orchestrated volume migration operation initiated in the block
storage service via the ``os-retype`` or ``os-migrate_volume``
volume actions. Direct usage of this API is not recommended and
may result in needing to hard reboot the server to update details
within the guest such as block storage serial IDs. Furthermore,
this API is only implemented by `certain compute drivers`_.
.. _certain compute drivers: https://docs.openstack.org/nova/latest/user/support-matrix.html#operation_swap_volume
Policy defaults enable only users with the administrative role to perform
this operation. Cloud providers can change these permissions through the
``policy.json`` file.
Updating, or what is commonly referred to as "swapping", volume attachments
with volumes that have more than one read/write attachment, is not supported.

Detach a volume from an instance
================================
.. rest_method:: DELETE /servers/{server_id}/os-volume_attachments/{volume_id}
Detach a volume from an instance.
Normal response codes: 202
Error response codes: badRequest(400), unauthorized(401), forbidden(403), itemNotFound(404), conflict(409)
.. note:: From v2.20 detach a volume from an instance in SHELVED or SHELVED_OFFLOADED
state is allowed.
