Overview

FlexVol volumes are logical containers used by ONTAP to serve data to clients. They contain file systems in a NAS environment and LUNs in a SAN environment.
A FlexGroup volume is a scale-out NAS container that provides high performance along with automatic load distribution and scalability. A FlexGroup volume contains several constituents that automatically and transparently share the traffic.
FlexClone volumes are writable, point-in-time copies of a FlexVol volume. At this time, FlexClones of FlexGroups are not supported.
Volumes with SnapLock type Compliance or Enterprise, are referred to as SnapLock volumes. Volumes with SnapLock type cannot be of FlexGroup style. Once a SnapLock aggregate is created, by default, volumes created inside the aggregate inherit the "snaplock" property from the aggregate.
ONTAP storage APIs allow you to create, modify, and monitor volumes and aggregates.

Storage efficiency

Storage efficiency is used to remove duplicate blocks in the data and to compress the data. Efficiency has deduplication, compression, cross volume deduplication, and compaction options. On all-flash systems, all efficiencies will be enabled by default on volume creation. Options such as "background/inline/both" will be treated as both, which means both background and inline will be enabled for any efficiency option. The option "none" will disable both background and inline efficiency.
To enable any efficiency option on all-flash or FAS systems, background deduplication is always enabled.

Quotas

Quotas provide a way to restrict or track the files and space usage by a user, group, or qtree. Quotas are enabled for a specific FlexVol or a FlexGroup volume.
The following APIs can be used to enable or disable and obtain quota state for a FlexVol or a FlexGroup volume: – PATCH /api/storage/volumes/{volume-uuid} -d '{"quota.enabled":"true"}' – PATCH /api/storage/volumes/{volume-uuid} -d '{"quota.enabled":"false"}' – GET /api/storage/volumes/{volume-uuid}/?fields=quota.state

QoS

QoS policy and settings enforce Service Level Objectives (SLO) on a volume. SLO can be set by specifying qos.max_throughput_iops and/or qos.max_throughput_mbps or qos.min_throughput_iops. Specifying min_throughput_iops is only supported on volumes hosted on an a node which is flash optimized. A pre-created QoS policy can also be used by specifying qos.name or qos.uuid property.

Performance monitoring

Performance of a volume can be monitored by the metric.* and statistics.* fields. These show the performance of the volume in terms of IOPS, latency and throughput. The metric.* fields denote an average whereas statistics.* fields denote a real-time monotonically increasing value aggregated across all nodes.

Volume APIs

The following APIs are used to perform operations related with FlexVols and FlexGroup volumes: – POST /api/storage/volumes – GET /api/storage/volumes – GET /api/storage/volumes/{uuid} – PATCH /api/storage/volumes/{uuid} – DELETE /api/storage/volumes/{uuid}

Classes

class Volume (*args, **kwargs)

Allows interaction with Volume objects on the host

Initialize the instance of the resource.

Any keyword arguments are set on the instance as properties. For example, if the class was named 'MyResource', then this statement would be true:

MyResource(name='foo').name == 'foo'

Args

*args
Each positional argument represents a parent key as used in the URL of the object. That is, each value will be used to fill in a segment of the URL which refers to some parent object. The order of these arguments must match the order they are specified in the URL, from left to right.
**kwargs
each entry will have its key set as an attribute name on the instance and its value will be the value of that attribute.

Ancestors

Static methods

def delete_collection(*args, connection: HostConnection = None, **kwargs) -> NetAppResponse

Deletes a volume. If the UUID belongs to a volume, all of its blocks are freed and returned to its containing aggregate. If a volume is online, it is offlined before deletion.

  • volume delete
  • volume clone delete

Delete all objects in a collection which match the given query.

All records on the host which match the query will be deleted.

Args

*args
Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to delete the collection of bars for a particular foo, the foo.name value should be passed.
connection
The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs
Any key/value pairs passed will be sent as query parameters to the host. Only resources matching this query will be patched.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

NetAppRestError: If the API call returned a status code >= 400

def find(*args, connection: HostConnection = None, **kwargs) -> Resource

Retrieves volumes.

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.

Find an instance of an object on the host given a query.

The host will be queried with the provided key/value pairs to find a matching resource. If 0 are found or if more than 1 is found, an error will be raised or returned. If there is exactly 1 matching record, then it will be returned.

Args

*args
Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to find a bar for a particular foo, the foo.name value should be passed.
connection
The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs
Any key/value pairs passed will be sent as query parameters to the host.

Returns

A Resource object containing the details of the object.

Raises

NetAppRestError: If the API call did not return exactly 1 matching resource.

Valid choices:

  • error
  • mixed
  • offline
  • online
var statistics

The statistics field of the volume.

var style

The style of the volume. If "style" is not specified, the volume type is determined based on the specified aggregates. Specifying a single aggregate, without "constituents_per_aggregate" creates a flexible volume. Specifying multiple aggregates, or a single aggregate with "constituents_per_aggregate" creates a FlexGroup. If "style" is specified, a volume of that type is created. That is, if style is "flexvol", a single aggregate must be specified. If style is "flexgroup", the system either uses the specified aggregates, or automatically provisions if no aggregates are specified.
flexvol ‐ flexible volumes and FlexClone volumes
flexgroup ‐ FlexGroups.

Valid choices:

  • flexvol
  • flexgroup
var svm

The svm field of the volume.

var tiering

The tiering field of the volume.

var type

Type of the volume.
rw ‐ read-write volume.
dp ‐ data-protection volume.

var use_mirrored_aggregates

Specifies whether mirrored aggregates are selected when provisioning a FlexGroup without specifying "aggregates.name" or "aggregates.uuid". Only mirrored aggregates are used if this parameter is set to 'true' and only unmirrored aggregates are used if this parameter is set to 'false'. Aggregate level mirroring for a FlexGroup can be changed by moving all of the constituents to the required aggregates. The default value is 'true' for a MetroCluster configuration and is 'false' for a non-MetroCluster configuration.

var uuid

Unique identifier for the volume. This corresponds to the instance-uuid that is exposed in the CLI and ONTAPI. It does not change due to a volume move.
