PATCH /storage/luns/{uuid}

Introduced In: 9.6

Updates an existing LUN in one of several ways:

  • Updates the properties of a LUN.

  • Writes data to a LUN. LUN data write requests are distinguished by the header entry Content-Type: multipart/form-data. When this header entry is provided, query parameter data.offset is required and used to specify the location within the LUN at which to write the data; no other query parameters are allowed. The request body must be multipart/form-data content with exactly one form entry containing the data to write. The content type entry of the form data is ignored and always treated as application/octet-stream. Writes are limited to one megabyte (1MB) per request.

  • Overwrites the contents of a LUN as a clone of another.

  • Begins the movement of a LUN between volumes. PATCH can also pause and resume the movement of a LUN between volumes that is already in active.

Parameters

Name Type In Required Description

uuid

string

path

True

The unique identifier of the LUN to retrieve.

data.offset

integer

query

False

The offset, in bytes, at which to begin writing LUN data.

LUN data write requests are distinguished by the header entry Content-Type: multipart/form-data. When this header entry is provided, query parameter data.offset is required and used to specify the location within the LUN at which to write the data; no other query parameters are allowed. The request body must be multipart/form-data content with exactly one form entry containing the data to write. The content type entry of the form data is ignored and always treated as application/octet-stream. Writes are limited to one megabyte (1MB) per request.

Request Body

Name Type Description

_links

_links

attributes

array[attributes]

An array of name/value pairs optionally stored with the LUN. Attributes are available to callers to persist small amounts of application-specific metadata. They are in no way interpreted by ONTAP.

Attribute names and values must be at least one byte and no more than 4091 bytes in length. The sum of the name and value lengths must be no more than 4092 bytes.

Valid in POST except when creating a LUN clone. A cloned can already have attributes from its source. You can add, modify, and delete the attributes of a LUN clone in separate requests after creation of the LUN.

Attributes may be added/modified/removed for an existing LUN using the /api/storage/luns/{lun.uuid}/attributes endpoint. For further information, see DOC /storage/luns/{lun.uuid}/attributes .

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

  • Introduced in: 9.10

  • readCreate: 1

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 computational 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.

class

string

The class of LUN.

Optional in POST.

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, space.guarantee.requested and space.scsi_thin_provisioning_support_enabled.

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.

consistency_group

consistency_group

The LUN's consistency group. This property is populated for LUNs that are members of a consistency group. If the LUN is a member of a child consistency group, the parent consistency group is reported.

Platform Specifics

  • Unified ONTAP: A LUN's consistency group is the consistency group of its containing volume.

  • ASA.Next: A LUN is optionally associated directly with a consistency group.

  • readOnly: 1

  • Introduced in: 9.10

convert

convert

This sub-object is used in POST to convert a valid in-place NVMe namespace to a LUN. Setting a property in this sub-object indicates that a conversion from the specified NVMe namespace to LUN is desired.

copy

copy

This sub-object applies to LUN copy operations. A LUN can be copied with a POST request that supplies copy.source properties.

Copying a LUN is an asynchronous activity begun by a POST request that specifies the source of the copy in the copy.source properties. The data for the LUN is then asynchronously copied from the source to the destination. The time required to complete the copy depends on the size of the LUN and the load on the cluster. The copy sub-object is populated while a LUN copy is in progress and for two (2) minutes following completion of a copy.

While LUNs are being copied, the status of the LUN copy operations can be obtained using a GET of the source or destination LUN that requests the copy properties. If the LUN is the source LUN for one or more copy operations, the copy.destinations array is populated in GET. If the containing LUN is the destination LUN for a copy operation, the copy.source sub-object is populated in GET. The LUN copy operation can be further modified using a PATCH on the properties on the copy.source sub-object of the copy destination LUN.

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

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.

encryption

encryption

Encryption related properties for the LUN.

Platform Specifics

  • Unified ONTAP: These properties are not available on the LUN object in the REST API and are not reported for GET requests. See the containing volume object for this information.

  • ASA.Next: Available for GET, POST and PATCH.

location

location

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

  • Introduced in: 9.6

lun_maps

array[lun_maps]

The LUN maps with which the LUN is associated.

There is an added computational 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 Requesting specific fields to learn more.

metric

metric

Performance numbers, such as IOPS latency and throughput.

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 an added computational 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 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.

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

  • Introduced in: 9.6

  • x-nullable: true

space

space

The storage space related properties of the LUN.

statistics

statistics

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

status

status

Status information about the LUN.

svm

svm

The SVM in which the LUN is located.

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

  • readOnly: 1

  • Introduced in: 9.6

  • x-nullable: true

vvol

vvol

A VMware virtual volume (vVol) binding is an association between a LUN of class protocol_endpoint and a LUN of class vvol. Class protocol_endpoint LUNs are mapped to igroups and granted access using the same configuration as class regular LUNs. When a class vvol LUN is bound to a mapped class protocol_endpoint LUN, VMware can access the class vvol LUN through the class protocol_endpoint LUN mapping.

See link:post-protocols-san-vvol-bindings(#-san-vvol-binding-create)tolearnmoreaboutcreatingvvolbindingsanddelete-protocols-san-vvol-bindings.htmlPOST /protocols/san/vvol-bindings to learn more about creating vVol bindings and [DELETE /protocols/san/vvol-bindings] to learn more about deleting vVol bindings.

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

copy

This sub-object applies to LUN copy operations. A LUN can be copied with a POST request that supplies copy.source properties.

Copying a LUN is an asynchronous activity begun by a POST request that specifies the source of the copy in the copy.source properties. The data for the LUN is then asynchronously copied from the source to the destination. The time required to complete the copy depends on the size of the LUN and the load on the cluster. The copy sub-object is populated while a LUN copy is in progress and for two (2) minutes following completion of a copy.

While LUNs are being copied, the status of the LUN copy operations can be obtained using a GET of the source or destination LUN that requests the copy properties. If the LUN is the source LUN for one or more copy operations, the copy.destinations array is populated in GET. If the containing LUN is the destination LUN for a copy operation, the copy.source sub-object is populated in GET. The LUN copy operation can be further modified using a PATCH on the properties on the copy.source sub-object of the copy destination LUN.

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

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.

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.

When a binding is deleted, the binding count is decremented, but the LUNs remain bound if the resultant reference count is greater than zero. When the binding count reaches zero, the binding is destroyed.

The bindings array contains LUNs of the opposite class of the containing LUN object.

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

is_bound

boolean

Reports if the LUN is part of a VMware virtual volume (vVol) bind relationship. This is true if the LUN is of class protocol_endpoint or vvol and has one or more bindings to a LUN of the opposite class. This is false if the LUN is of class regular or unbound.

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.

attributes

array[attributes]

An array of name/value pairs optionally stored with the LUN. Attributes are available to callers to persist small amounts of application-specific metadata. They are in no way interpreted by ONTAP.

Attribute names and values must be at least one byte and no more than 4091 bytes in length. The sum of the name and value lengths must be no more than 4092 bytes.

Valid in POST except when creating a LUN clone. A cloned can already have attributes from its source. You can add, modify, and delete the attributes of a LUN clone in separate requests after creation of the LUN.

Attributes may be added/modified/removed for an existing LUN using the /api/storage/luns/{lun.uuid}/attributes endpoint. For further information, see DOC /storage/luns/{lun.uuid}/attributes .

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

  • Introduced in: 9.10

  • readCreate: 1

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 computational 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.

class

string

The class of LUN.

Optional in POST.

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, space.guarantee.requested and space.scsi_thin_provisioning_support_enabled.

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.

consistency_group

consistency_group

The LUN's consistency group. This property is populated for LUNs that are members of a consistency group. If the LUN is a member of a child consistency group, the parent consistency group is reported.

Platform Specifics

  • Unified ONTAP: A LUN's consistency group is the consistency group of its containing volume.

  • ASA.Next: A LUN is optionally associated directly with a consistency group.

  • readOnly: 1

  • Introduced in: 9.10

convert

convert

This sub-object is used in POST to convert a valid in-place NVMe namespace to a LUN. Setting a property in this sub-object indicates that a conversion from the specified NVMe namespace to LUN is desired.

copy

copy

This sub-object applies to LUN copy operations. A LUN can be copied with a POST request that supplies copy.source properties.

Copying a LUN is an asynchronous activity begun by a POST request that specifies the source of the copy in the copy.source properties. The data for the LUN is then asynchronously copied from the source to the destination. The time required to complete the copy depends on the size of the LUN and the load on the cluster. The copy sub-object is populated while a LUN copy is in progress and for two (2) minutes following completion of a copy.

While LUNs are being copied, the status of the LUN copy operations can be obtained using a GET of the source or destination LUN that requests the copy properties. If the LUN is the source LUN for one or more copy operations, the copy.destinations array is populated in GET. If the containing LUN is the destination LUN for a copy operation, the copy.source sub-object is populated in GET. The LUN copy operation can be further modified using a PATCH on the properties on the copy.source sub-object of the copy destination LUN.

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

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.

encryption

encryption

Encryption related properties for the LUN.

Platform Specifics

  • Unified ONTAP: These properties are not available on the LUN object in the REST API and are not reported for GET requests. See the containing volume object for this information.

  • ASA.Next: Available for GET, POST and PATCH.

location

location

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

  • Introduced in: 9.6

lun_maps

array[lun_maps]

The LUN maps with which the LUN is associated.

There is an added computational 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 Requesting specific fields to learn more.

metric

metric

Performance numbers, such as IOPS latency and throughput.

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 an added computational 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 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.

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

  • Introduced in: 9.6

  • x-nullable: true

space

space

The storage space related properties of the LUN.

statistics

statistics

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

status

status

Status information about the LUN.

svm

svm

The SVM in which the LUN is located.

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

  • readOnly: 1

  • Introduced in: 9.6

  • x-nullable: true

vvol

vvol

A VMware virtual volume (vVol) binding is an association between a LUN of class protocol_endpoint and a LUN of class vvol. Class protocol_endpoint LUNs are mapped to igroups and granted access using the same configuration as class regular LUNs. When a class vvol LUN is bound to a mapped class protocol_endpoint LUN, VMware can access the class vvol LUN through the class protocol_endpoint LUN mapping.
