GET /application/consistency-groups/{uuid}

Introduced In: 9.10

Retrieves a single consistency group.

Expensive properties

There is an added cost to retrieving values for these properties. They are not included by default in GET results and must be explicitly requested using the fields query parameter. See DOC Requesting specific fields to learn more.

  • volumes

  • luns

  • namespaces

There are no ONTAP commands for managing consistency groups.

_links

self_link

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.

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

  • x-ntap-modifyOnly: true

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_source

boolean

Indicates whether or not this consistency group is the source for replication.

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.

svm

svm_reference

SVM, applies only to SVM-scoped objects.

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

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.

  • Introduced in: 9.6

used

integer

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. Without specific knowledge of how the LUN blocks are utilized outside of ONTAP, this property should not be used as an indicator for an out-of-space condition.

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.

Name Type Description

When used in a PATCH, the patched LUN's data is over-written as a clone of the source and the following properties are preserved from the patched LUN unless otherwise specified as part of the PATCH: class, auto_delete, lun_maps, serial_number, status.state, and uuid.

Persistent reservations for the patched LUN are also preserved.

comment

string

A configurable comment available for use by the administrator. Valid in POST and PATCH.

create_time

string

The time the LUN was created.

enabled

boolean

The enabled state of the LUN. LUNs can be disabled to prevent access to the LUN. Certain error conditions also cause the LUN to become disabled. If the LUN is disabled, you can consult the state property to determine if the LUN is administratively disabled (offline) or has become disabled as a result of an error. A LUN in an error condition can be brought online by setting the enabled property to true or brought administratively offline by setting the enabled property to false. Upon creation, a LUN is enabled by default. Valid in PATCH.

lun_maps

array[lun_maps]

An array of LUN maps.

A LUN map is an association between a LUN and an initiator group. When a LUN is mapped to an initiator group, the initiator group's initiators are granted access to the LUN. The relationship between a LUN and an initiator group is many LUNs to many initiator groups.

name

string

The fully qualified path name of the LUN composed of the "/vol" prefix, the volume name, the qtree name (optional), and the base name of the LUN. Valid in POST and PATCH.

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.

Name Type Description

auto_delete

boolean

This property marks the NVMe namespace for auto deletion when the volume containing the namespace runs out of space. This is most commonly set on namespace clones.

When set to true, the NVMe namespace becomes eligible for automatic deletion when the volume runs out of space. Auto deletion only occurs when the volume containing the namespace is also configured for auto deletion and free space in the volume decreases below a particular threshold.

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. See Requesting specific fields to learn more.

comment

string

A configurable comment available for use by the administrator. Valid in POST and PATCH.

create_time

string

The time the NVMe namespace was created.

enabled

boolean

The enabled state of the NVMe namespace. Certain error conditions cause the namespace to become disabled. If the namespace is disabled, you can check the state property to determine what error disabled the namespace. An NVMe namespace is enabled automatically when it is created.

name

string

The fully qualified path name of the NVMe namespace composed of a "/vol" prefix, the volume name, the (optional) qtree name and base name of the namespace. Valid in POST.

NVMe namespaces do not support rename, or movement between volumes.

os_type

string

The operating system type of the NVMe namespace.

Required in POST when creating an NVMe namespace that is not a clone of another. Disallowed in POST when creating a namespace clone.

provisioning_options

subsystem_map

array[subsystem_map]

The NVMe subsystem with which the NVMe namespace is associated. A namespace can be mapped to zero (0) or one (1) subsystems.

There is an added cost to retrieving property values for subsystem_map. They are not populated for either a collection GET or an instance GET unless explicitly requested using the fields query parameter.

all ‐ Allows tiering of both Snapshot copies and active file system user data to the cloud store as soon as possible by ignoring the temperature on the volume blocks.

auto ‐ Allows tiering of both snapshot and active file system user data to the cloud store

none ‐ Volume blocks are not be tiered to the cloud store.

snapshot_only ‐ Allows tiering of only the volume Snapshot copies not associated with the active file system.

The default tiering policy is "snapshot-only" for a FlexVol volume and "none" for a FlexGroup volume. The default minimum cooling period for the "snapshot-only" tiering policy is 2 days and for the "auto" tiering policy it is 31 days.

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.
