POST /storage/luns

Creates a LUN.

Required properties

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

  • name, location.volume.name or location.volume.uuid - Existing volume in which to create the LUN.

  • name or location.logical_unit - Base name of the LUN.

  • os_type - Operating system from which the LUN will be accessed. Required when creating a non-clone LUN and disallowed when creating a clone of an existing LUN. A clone's os_type is taken from the source LUN.

  • space.size - Size of the LUN. Required when creating a non-clone LUN and disallowed when creating a clone of an existing LUN. A clone's size is taken from the source LUN.

  • qos_policy.name or qos_policy.uuid - Existing traditional or adaptive QoS policy to be applied to the LUN. All LUNs should be managed by a QoS policy at the volume or LUN level.

Default property values

If not specified in POST, the follow default property values are assigned.

  • auto_delete - false

  • lun create

  • volume file clone autodelete

  • volume file clone create

Request Body

Name Type Description

_links

_links

auto_delete

boolean

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

When set to true, the LUN becomes eligible for automatic deletion when the volume runs out of space. Auto deletion only occurs when the volume containing the LUN 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 LUN 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 DOC Requesting specific fields to learn more.

class

string

The class of LUN. Only regular LUNs can be created using the REST API.

clone

clone

This sub-object is used in POST to create a new LUN as a clone of an existing LUN, or PATCH to overwrite an existing LUN as a clone of another. Setting a property in this sub-object indicates that a LUN clone is desired. Consider the following other properties when cloning a LUN: auto_delete, qos_policy, and space.guarantee.requested.

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.

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.

location

location

The location of the LUN within the ONTAP cluster. Valid in POST and PATCH.

lun_maps

array[lun_maps]

The LUN maps with which the LUN is associated.

There is an added cost to retrieving property values for lun_maps. They are not populated for either a collection GET or an instance GET unless explicitly requested using the fields query parameter. See DOC Requesting specific fields to learn more.

movement

movement

This sub-object applies to LUN movement between volumes. A LUN can be moved to a new volume with a PATCH request that changes either the volume portion of property name, location.volume.uuid, or location.volume.name. If the volume is changed using more than one of these properties, the supplied properties used must refer to the same volume.

Moving a LUN between volumes is an asynchronous activity begun by a PATCH request. The data for the LUN is then asynchronously copied from the source volume to the destination volume. The time required to complete the move depends on the size of the LUN and the load on the cluster. The movement sub-object is populated while a LUN movement is in progress and for two (2) minutes following completion of a movement.

While the LUN is being moved, the status of the LUN movement operation can be obtained using a GET for the LUN that requests the movement properties. The LUN movement operation can be further modified using a PATCH on the properties on the movement sub-object.

There is added cost to retrieving property values for movement. They are not populated for either a collection GET or an instance GET unless explicitly requested using the fields query parameter. See DOC Requesting specific fields to learn more.

name

string

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

A PATCH that modifies the qtree and/or base name portion of the LUN path is considered a rename operation.

A PATCH that modifies the volume portion of the LUN path begins an asynchronous LUN movement operation.

os_type

string

The operating system type of the LUN.

Required in POST when creating a LUN that is not a clone of another. Disallowed in POST when creating a LUN clone.

qos_policy

qos_policy

The QoS policy for the LUN. Both traditional and adaptive QoS policies are supported. If both property qos_policy.uuid and qos_policy.name are specified in the same request, they must refer to the same QoS policy. To remove the QoS policy from a LUN, leaving it with no QoS policy, set property qos_policy.name to an empty string ("") in a PATCH request. Valid in POST and PATCH.

Note that a QoS policy can be set on a LUN, or a LUN's volume, but not both.

serial_number

string

The LUN serial number. The serial number is generated by ONTAP when the LUN is created.

  • maxLength: 12

  • minLength: 12

  • readOnly: 1

space

space

The storage space related properties of the LUN.

status

status

Status information about the LUN.

svm

svm

SVM, applies only to SVM-scoped objects.

uuid

string

The unique identifier of the LUN. The UUID is generated by ONTAP when the LUN is created.

Valid in PATCH when an LUN movement is active. Set to paused to pause a LUN movement. Set to replicating to resume a paused LUN movement.

volume_snapshot_blocked

boolean

This property reports if volume Snapshot copies are blocked by the LUN movement. This property can be polled to identify when volume Snapshot copies can be resumed after beginning a LUN movement.

movement

This sub-object applies to LUN movement between volumes. A LUN can be moved to a new volume with a PATCH request that changes either the volume portion of property name, location.volume.uuid, or location.volume.name. If the volume is changed using more than one of these properties, the supplied properties used must refer to the same volume.

Moving a LUN between volumes is an asynchronous activity begun by a PATCH request. The data for the LUN is then asynchronously copied from the source volume to the destination volume. The time required to complete the move depends on the size of the LUN and the load on the cluster. The movement sub-object is populated while a LUN movement is in progress and for two (2) minutes following completion of a movement.

While the LUN is being moved, the status of the LUN movement operation can be obtained using a GET for the LUN that requests the movement properties. The LUN movement operation can be further modified using a PATCH on the properties on the movement sub-object.

There is added cost to retrieving property values for movement. They are not populated for either a collection GET or an instance GET unless explicitly requested using the fields query parameter. See DOC Requesting specific fields to learn more.

Name Type Description

max_throughput

string

The maximum data throughput that should be utilized in support of the LUN movement. This property can be used to throttle a transfer and limit its impact on the performance of the source and destination nodes. The specified value will be rounded up to the nearest megabyte.

If this property is not specified in a POST that begins a LUN movement, throttling is not applied to the data transfer.

For more information, see Size properties in the docs section of the ONTAP REST API documentation.

This property is valid only in a POST that begins a LUN movement or a PATCH when a LUN movement is already in process.

paths

paths

The fully qualified LUN path names involved in the LUN movement.

progress

progress

qos_policy

The QoS policy for the LUN. Both traditional and adaptive QoS policies are supported. If both property qos_policy.uuid and qos_policy.name are specified in the same request, they must refer to the same QoS policy. To remove the QoS policy from a LUN, leaving it with no QoS policy, set property qos_policy.name to an empty string ("") in a PATCH request. Valid in POST and PATCH.

Note that a QoS policy can be set on a LUN, or a LUN's volume, but not both.

Name Type Description

_links

The requested space reservation policy for the LUN. If true, a space reservation is requested for the LUN; if false, the LUN is thin provisioned. Guaranteeing a space reservation request for a LUN requires that the volume in which the LUN resides is also space reserved and that the fractional reserve for the volume is 100%. Valid in POST and PATCH.

reserved

boolean

Reports if the LUN is space guaranteed.

If true, a space guarantee is requested and the containing volume and aggregate support the request. If false, a space guarantee is not requested or a space guarantee is requested and either the containing volume or aggregate do not support the request.

space

The storage space related properties of the LUN.

Name Type Description

guarantee

guarantee

Properties that request and report the space guarantee for the LUN.

size

integer

The total provisioned size of the LUN. The LUN size can be increased but not be made smaller using the REST interface.

For more information, see Size properties in the docs section of the ONTAP REST API documentation.

  • example: 1073741824

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.

For more information, see Size properties in the docs section of the ONTAP REST API documentation.

status

Status information about the LUN.

Name Type Description

container_state

string

The state of the volume and aggregate that contain the LUN. LUNs are only available when their containers are available.

mapped

boolean

Reports if the LUN is mapped to one or more initiator groups.

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 DOC Requesting specific fields to learn more.

read_only

boolean

Reports if the LUN allows only read access.

state

string

The state of the LUN. Normal states for a LUN are online and offline. Other states indicate errors.

svm

SVM, applies only to SVM-scoped objects.

Name Type Description

_links

_links

name

string

The name of the SVM.

uuid

string

The unique identifier of the SVM.

lun

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

_links

_links

auto_delete

boolean

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

When set to true, the LUN becomes eligible for automatic deletion when the volume runs out of space. Auto deletion only occurs when the volume containing the LUN 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 LUN 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 DOC Requesting specific fields to learn more.

class

string

The class of LUN. Only regular LUNs can be created using the REST API.

clone

clone

This sub-object is used in POST to create a new LUN as a clone of an existing LUN, or PATCH to overwrite an existing LUN as a clone of another. Setting a property in this sub-object indicates that a LUN clone is desired. Consider the following other properties when cloning a LUN: auto_delete, qos_policy, and space.guarantee.requested.

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.

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.

location

location

The location of the LUN within the ONTAP cluster. Valid in POST and PATCH.

lun_maps

array[lun_maps]

The LUN maps with which the LUN is associated.

There is an added cost to retrieving property values for lun_maps. They are not populated for either a collection GET or an instance GET unless explicitly requested using the fields query parameter. See DOC Requesting specific fields to learn more.

movement

movement

This sub-object applies to LUN movement between volumes. A LUN can be moved to a new volume with a PATCH request that changes either the volume portion of property name, location.volume.uuid, or location.volume.name. If the volume is changed using more than one of these properties, the supplied properties used must refer to the same volume.

Moving a LUN between volumes is an asynchronous activity begun by a PATCH request. The data for the LUN is then asynchronously copied from the source volume to the destination volume. The time required to complete the move depends on the size of the LUN and the load on the cluster. The movement sub-object is populated while a LUN movement is in progress and for two (2) minutes following completion of a movement.

While the LUN is being moved, the status of the LUN movement operation can be obtained using a GET for the LUN that requests the movement properties. The LUN movement operation can be further modified using a PATCH on the properties on the movement sub-object.

There is added cost to retrieving property values for movement. They are not populated for either a collection GET or an instance GET unless explicitly requested using the fields query parameter. See DOC Requesting specific fields to learn more.

name

string

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

A PATCH that modifies the qtree and/or base name portion of the LUN path is considered a rename operation.

A PATCH that modifies the volume portion of the LUN path begins an asynchronous LUN movement operation.

os_type

string

The operating system type of the LUN.

Required in POST when creating a LUN that is not a clone of another. Disallowed in POST when creating a LUN clone.

qos_policy

qos_policy

The QoS policy for the LUN. Both traditional and adaptive QoS policies are supported. If both property qos_policy.uuid and qos_policy.name are specified in the same request, they must refer to the same QoS policy. To remove the QoS policy from a LUN, leaving it with no QoS policy, set property qos_policy.name to an empty string ("") in a PATCH request. Valid in POST and PATCH.

Note that a QoS policy can be set on a LUN, or a LUN's volume, but not both.

serial_number

string

The LUN serial number. The serial number is generated by ONTAP when the LUN is created.

  • maxLength: 12

  • minLength: 12

  • readOnly: 1

space

space

The storage space related properties of the LUN.

status

status

Status information about the LUN.

svm

svm

SVM, applies only to SVM-scoped objects.

uuid

string

The unique identifier of the LUN. The UUID is generated by ONTAP when the LUN is created.

  • example: 1cd8a442-86d1-11e0-ae1c-123478563412
