POST /application/consistency-groups

Introduced In: 9.10

Creates a consistency group with one or more consistency groups having:

  • new SAN volumes,

  • existing SAN, NVMe or NAS FlexVol volumes in a new or existing consistency group

Required properties

  • svm.uuid or svm.name - Existing SVM in which to create the group.

  • volumes, luns or namespaces

Naming Conventions

Consistency groups

  • name or consistency_groups[].name, if specified

  • derived from volumes[0].name, if only one volume is specified, same as volume name

Volume

  • volumes[].name, if specified

  • derived from volume prefix in luns[].name

  • derived from cg[].name, suffixed by "_#" where "#" is a system generated unique number

  • suffixed by "_#" where "#" is a system generated unique number, if provisioning_options.count is provided

LUN

  • luns[].name, if specified

  • derived from volumes[].name, suffixed by "_#" where "#" is a system generated unique number

  • suffixed by "_#" where "#" is a system generated unique number, if provisioning_options.count is provided

NVMe Namespace

  • namespaces[].name, if specified

  • derived from volumes[].name, suffixed by "_#" where "#" is a system generated unique number

  • suffixed by "_#" where "#" is a system generated unique number, if provisioning_options.count is provided

There are no ONTAP commands for managing consistency group.

Parameters

Name Type In Required Description

return_timeout

integer

query

False

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

return_records

boolean

query

False

The default is false. If set to true, the records are returned.

  • Default value:

Request Body

Name Type Description

_links

self_link

application

application

clone

clone

Creates a clone of an existing consistency group from the current contents or an existing Snapshot copy.

consistency_groups

array[consistency_groups]

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[luns]

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.

metric

metric

Performance and capacity numbers, such as, IOPS, latency, throughput, used space, and available space.

name

string

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[namespaces]

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.

  • maxItems: 16

  • minItems: 0

  • uniqueItems: 1

  • Introduced in: 9.10

parent_consistency_group

parent_consistency_group

The parent consistency group.

provisioning_options

provisioning_options

Options that are applied to the operation.

qos

qos

replicated

boolean

Indicates whether or not replication has been enabled on this consistency group.

replication_relationships

array[replication_relationships]

Indicates the SnapMirror relationship of this consistency group.

replication_source

boolean

Since support for this field is to be removed in the next release, use replication_relationships.is_source instead.

restore_to

restore_to

Use to restore a consistency group to a previous Snapshot copy

snapshot_policy

snapshot_policy_reference

This is a reference to the Snapshot copy policy.

space

space

Space information for the consistency group.

statistics

statistics

These are raw performance and space numbers, such as, IOPS, latency, throughput, used space, and available space. These numbers are aggregated across all nodes in the cluster and increase with the uptime of the cluster.

svm

svm

The Storage Virtual Machine (SVM) in which the consistency group is located.

tiering

tiering

The tiering placement and policy definitions for volumes in this consistency group.

uuid

string

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

  • readOnly: 1

  • Introduced in: 9.10

  • x-nullable: true

volumes

array[volumes]

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.

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.

An empty path in PATCH deactivates and unmounts the volume. Taking a volume offline or restricted state removes its junction path. This attribute is reported in GET only when the volume is mounted.

security_style

string

Security style associated with the volume. Valid in POST or PATCH. mixed ‐ Mixed-style security ntfs ‐ NTFS/WIndows-style security unified ‐ Unified-style security, unified UNIX, NFS and CIFS permissions unix ‐ UNIX-style security.

integer

The UNIX user ID of the volume. Valid in POST or PATCH.

unix_permissions

integer

UNIX permissions to be viewed as an octal number, consisting of 4 digits derived by adding up bits 4 (read), 2 (write), and 1 (execute). First digit selects the set user ID (4), set group ID (2), and sticky (1) attributes. Second digit selects permission for the owner of the file. Third selects permissions for other users in the same group while the fourth selects permissions for other users not in the group. Valid in POST or PATCH. For security style "mixed" or "unix", the default setting is 0755 in octal (493 in decimal) and for security style "ntfs", the default setting is 0000. In cases where only owner, group, and other permissions are given (as in 755, representing the second, third and fourth digit), the first digit is assumed to be zero.

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.
