PATCH /application/consistency-groups/{uuid}

Introduced In: 9.10

Updates a consistency group.

that this operation will never delete storage elements. You can specify only elements that should be added to the consistency group regardless of existing storage objects.

N/A. There are no ONTAP commands for managing consistency groups.

Examples:

Adding namespaces to an existing volume in an existing consistency group

To add two NVMe Namespaces to an existing volume in an existing consistency group, create a new subsystem and bind the new namespaces to it.

curl -X PATCH 'https://<mgmt-ip>/api/application/consistency-groups/6f51748a-0a7f-11ec-a449-005056bbcf9f' -d '{ "namespaces": [ { "name": "/vol/vol1/new_namespace", "space": { "size": "10M" }, "os_type": "windows", "provisioning_options": { "count": 2 }, "subsystem_map": { "subsystem": { "name": "mySubsystem", "hosts": [ { "nqn": "nqn.1992-08.com.netapp:sn.d04594ef915b4c73b642169e72e4c0b1:subsystem.host1" }, { "nqn": "nqn.1992-08.com.netapp:sn.d04594ef915b4c73b642169e72e4c0b1:subsystem.host2" } ] } } } ] }'

### Response:

{ "job": { "uuid": "8c9cabf3-0a88-11ec-a449-005056bbcf9f", "_links": { "self": { "href": "/api/cluster/jobs/8c9cabf3-0a88-11ec-a449-005056bbcf9f" } } } }

== Parameters

[cols=5*,options=header]
|===

|Name
|Type
|In
|Required
|Description

|uuid
|string
|path
|True
a|The unique identifier of the consistency group to modify.


|return_timeout
|integer
|query
|False
a|The number of seconds to allow the call to execute before returning. When doing a POST, PATCH, or DELETE operation on a single record, the default is 0 seconds.  This means that if an asynchronous operation is started, the server immediately returns HTTP code 202 (Accepted) along with a link to the job.  If a non-zero value is specified for POST, PATCH, or DELETE operations, ONTAP waits that length of time to see if the job completes so it can return something other than 202.

* Default value: 1
* Max value: 120
* Min value: 0

|consistency_groups
|array[link:#consistency_groups[consistency_groups]]
a|A consistency group is a mutually exclusive aggregation of volumes or other consistency groups. A consistency group can only be associated with one direct parent consistency group.


|luns
|array[link:#luns[luns]]
a|The LUNs array can be used to create or modify LUNs in a consistency group on a new or existing volume that is a member of the consistency group. LUNs are considered members of a consistency group if they are located on a volume that is a member of the consistency group.


|name
|string
a|Name of the consistency group. The consistency group name must be unique within an SVM.

If not provided and the consistency group contains only one volume, the name will be generated based on the volume name. If the consistency group contains more than one volume, the name is required.


|namespaces
|array[link:#namespaces[namespaces]]
a|An NVMe namespace is a collection of addressable logical blocks presented to hosts connected to the SVM using the NVMe over Fabrics protocol.
In ONTAP, an NVMe namespace is located within a volume. Optionally, it can be located within a qtree in a volume.

An NVMe namespace is created to a specified size using thin or thick provisioning as determined by the volume on which it is created. NVMe namespaces support being cloned. An NVMe namespace cannot be renamed, resized, or moved to a different volume. NVMe namespaces do not support the assignment of a QoS policy for performance management, but a QoS policy can be assigned to the volume containing the namespace. See the NVMe namespace object model to learn more about each of the properties supported by the NVMe namespace REST API.

An NVMe namespace must be mapped to an NVMe subsystem to grant access to the subsystem's hosts. Hosts can then access the NVMe namespace and perform I/O using the NVMe over Fabrics protocol.

|parent_consistency_group
|link:#parent_consistency_group[parent_consistency_group]
a|The parent consistency group.


|provisioning_options
|link:#provisioning_options[provisioning_options]
a|Options that are applied to the operation.


|qos
|link:#qos[qos]
a|

|replicated
|boolean
a|Indicates whether or not replication has been enabled on this consistency group.


|replication_source
|boolean
a|Indicates whether or not this consistency group is the source for replication.


|restore_to
|link:#restore_to[restore_to]
a|Use to restore a consistency group to a previous Snapshot copy


|snapshot_policy
|link:#snapshot_policy_reference[snapshot_policy_reference]
a|This is a reference to the Snapshot copy policy.


|space
|link:#space[space]
a|Space information for the consistency group.


|svm
|link:#svm[svm]
a|The Storage Virtual Machine (SVM) in which the consistency group is located.


|tiering
|link:#tiering[tiering]
a|The tiering placement and policy definitions for volumes in this consistency group.


|uuid
|string
a|The unique identifier of the consistency group. The UUID is generated by ONTAP when the consistency group is created.

* example: 1cd8a442-86d1-11e0-ae1c-123478563412
* Introduced in: 9.10
* readOnly: 1


|volumes
|array[link:#volumes[volumes]]
a|A consistency group is a mutually exclusive aggregation of volumes or other consistency groups. A volume can only be associated with one direct parent consistency group.

The volumes array can be used to create new volumes in the consistency group, add existing volumes to the consistency group, or modify existing volumes that are already members of the consistency group.

The total number of volumes across all child consistency groups contained in a consistency group is constrained by the same limit.

|used
|integer
a|The amount of space consumed by the main data stream of the LUN.

This value is the total space consumed in the volume by the LUN, including filesystem overhead, but excluding prefix and suffix streams. Due to internal filesystem overhead and the many ways SAN filesystems and applications utilize blocks within a LUN, this value does not necessarily reflect actual consumption/availability from the perspective of the filesystem or application.

[#luns]
[.api-collapsible-fifth-title]
luns

A LUN is the logical representation of storage in a storage area network (SAN).

In ONTAP, a LUN is located within a volume. Optionally, it can be located within a qtree in a volume.

A LUN can be created to a specified size using thin or thick provisioning. A LUN can then be renamed, resized, cloned, and moved to a different volume. LUNs support the assignment of a quality of service (QoS) policy for performance management or a QoS policy can be assigned to the volume containing the LUN. See the LUN object model to learn more about each of the properties supported by the LUN REST API.

A LUN must be mapped to an initiator group to grant access to the initiator group's initiators (client hosts). Initiators can then access the LUN and perform I/O over a Fibre Channel (FC) fabric using the Fibre Channel Protocol or a TCP/IP network using iSCSI.

[#namespaces]
[.api-collapsible-fifth-title]
namespaces

An NVMe namespace is a collection of addressable logical blocks presented to hosts connected to the storage virtual machine using the NVMe over Fabrics protocol.

In ONTAP, an NVMe namespace is located within a volume. Optionally, it can be located within a qtree in a volume.

An NVMe namespace is created to a specified size using thin or thick provisioning as determined by the volume on which it is created. NVMe namespaces support being cloned. An NVMe namespace cannot be renamed, resized, or moved to a different volume. NVMe namespaces do not support the assignment of a QoS policy for performance management, but a QoS policy can be assigned to the volume containing the namespace. See the NVMe namespace object model to learn more about each of the properties supported by the NVMe namespace REST API.

An NVMe namespace must be mapped to an NVMe subsystem to grant access to the subsystem's hosts. Hosts can then access the NVMe namespace and perform I/O using the NVMe over Fabrics protocol.

This property is optional in POST and PATCH. The default value for a new NVMe namespace is _false_.

There is an added cost to retrieving this property's value. It is not populated for either a collection GET or an instance GET unless it is explicitly requested using the `fields` query parameter.

If not provided and the consistency group contains only one volume, the name will be generated based on the volume name. If the consistency group contains more than one volume, the name is required.


|namespaces
|array[link:#namespaces[namespaces]]
a|An NVMe namespace is a collection of addressable logical blocks presented to hosts connected to the SVM using the NVMe over Fabrics protocol.
In ONTAP, an NVMe namespace is located within a volume. Optionally, it can be located within a qtree in a volume.

An NVMe namespace is created to a specified size using thin or thick provisioning as determined by the volume on which it is created. NVMe namespaces support being cloned. An NVMe namespace cannot be renamed, resized, or moved to a different volume. NVMe namespaces do not support the assignment of a QoS policy for performance management, but a QoS policy can be assigned to the volume containing the namespace. See the NVMe namespace object model to learn more about each of the properties supported by the NVMe namespace REST API.

An NVMe namespace must be mapped to an NVMe subsystem to grant access to the subsystem's hosts. Hosts can then access the NVMe namespace and perform I/O using the NVMe over Fabrics protocol.

|volumes
|array[link:#volumes[volumes]]
a|A consistency group is a mutually exclusive aggregation of volumes or other consistency groups. A volume can only be associated with one direct parent consistency group.

The volumes array can be used to create new volumes in the consistency group, add existing volumes to the consistency group, or modify existing volumes that are already members of the consistency group.

The total number of volumes across all child consistency groups contained in a consistency group is constrained by the same limit.
