Overview

A LUN is the logical representation of storage in a storage area network (SAN).
The LUN REST API allows you to create, update, delete, and discover LUNs.
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, moved to a different volume and copied. 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 FC Protocol or a TCP/IP network using iSCSI.

Performance monitoring

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

Examples

Creating a LUN

This example creates a 300 gigabyte, thin-provisioned LUN in SVM svm1, volume vol1, configured for use by linux initiators. The return_records query parameter is used to retrieve properties of the newly created LUN in the POST response.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Lun

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Lun()
    resource.svm = {"name": "svm1"}
    resource.os_type = "linux"
    resource.space = {"size": "300G"}
    resource.name = "/vol/vol1/lun1"
    resource.post(hydrate=True)
    print(resource)

Lun(
    {

Updating a LUN

This example sets the comment property of a LUN.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Lun

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Lun(uuid="5a24ae5b-28af-47fb-b129-5adf6cfba0a6")
    resource.comment = "Data for the finance department."
    resource.patch()


Retrieving LUNs

This example retrieves summary information for all online LUNs in SVM svm1. The svm.name and status.state query parameters are used to find the desired LUNs.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Lun

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    print(list(Lun.get_collection(**{"svm.name": "svm1", "status.state": "online"})))

[
    Lun(
        {
            "_links": {
                "self": {
                    "href": "/api/storage/luns/5a24ae5b-28af-47fb-b129-5adf6cfba0a6"
                }
            },
            "uuid": "5a24ae5b-28af-47fb-b129-5adf6cfba0a6",
            "status": {"state": "online"},
            "svm": {"name": "svm1"},
            "name": "/vol/vol1/lun1",
        }
    ),
    Lun(
        {
            "_links": {
                "self": {
                    "href": "/api/storage/luns/c903a978-9bac-4ce9-8237-4a3ba8b13f08"
                }
            },
            "uuid": "c903a978-9bac-4ce9-8237-4a3ba8b13f08",
            "status": {"state": "online"},
            "svm": {"name": "svm1"},
            "name": "/vol/vol1/lun2",
        }
    ),
    Lun(
        {
            "_links": {
                "self": {
                    "href": "/api/storage/luns/7faf0a9e-0a47-4876-8318-3638d5da16bf"
                }
            },

            "name": "/vol/vol2/lun3",
        }
    ),
]


Retrieving details for a specific LUN

In this example, the fields query parameter is used to request all fields, including advanced fields, that would not otherwise be returned by default for the LUN.

Cloning LUNs

A clone of a LUN is an independent "copy" of the LUN that shares unchanged data blocks with the original. As blocks of the source and clone are modified, unique blocks are written for each. LUN clones can be created quickly and consume very little space initially. They can be created for the purpose of back-up, or to replicate data for multiple consumers.
Space reservations can be set for the LUN clone independent of the source LUN by setting the space.guarantee.requested property in a POST or PATCH request.
A LUN clone can be set to auto-delete by setting the auto_delete property. If the LUN's volume is configured for automatic deletion, LUNs that have auto-delete enabled are deleted when a volume is nearly full to reclaim a target amount of free space in the volume.
The value of property space.scsi_thin_provisioning_support_enabled is not propagated to the destination when a LUN is cloned as a new LUN; it is reset to false. The value of this property is maintained from the destination LUN when a LUN is overwritten as a clone.

Examples

Creating a new LUN clone

You create a new LUN clone as you create any LUN - a POST request to /storage/luns. Set clone.source.uuid or clone.source.name to identify the source LUN from which the clone is created. The LUN clone and its source must reside in the same volume.
The source LUN can reside in a Snapshot copy, in which case the clone.source.name field must be used to identify it. Add /.snapshot/<snapshot_name> to the path after the volume name to identify the Snapshot copy. For example /vol/vol1/.snapshot/snap1/lun1.
By default, new LUN clones do not inherit the QoS policy of the source LUN; a QoS policy should be set for the clone by setting the qos_policy property.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Lun

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Lun()
    resource.svm = {"name": "svm1"}
    resource.name = "/vol/vol1/lun2clone1"
    resource.clone = {"source": {"name": "/vol/vol1/lun2"}}
    resource.qos_policy = {"name": "qos1"}
    resource.post(hydrate=True)
    print(resource)

Over-writing an existing LUN's data as a clone of another

You can overwrite an existing LUN as a clone of another, using a PATCH request to /storage/luns/{uuid}. Set the clone.source.uuid or clone.source.name property to identify the source LUN from which the clone data is taken. The LUN clone and its source must reside in the same volume.
When used in a PATCH request, the patched LUN's data is overwritten as a clone of the source. The following properties are preserved from the patched LUN unless otherwise specified as part of the PATCH: class, auto_delete, lun_maps, vvol, serial_number, status.state, and uuid.
Persistent reservations for the updated LUN are also preserved.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Lun

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Lun(uuid="5a24ae5b-28af-47fb-b129-5adf6cfba0a6")
    resource.clone = {"source": {"name": "/vol/vol1/lun2"}}
    resource.patch()


Moving LUNs between volumes

You move a LUN between volumes by using a PATCH request to /storage/luns/{uuid}. Set the volume portion of the fully qualified LUN path name property, path.volume.uuid, or path.volume.name property to a different volume than the LUN's current volume. Moving a LUN between volumes is an asynchronous activity. A successful request returns a response of 200 synchronously, which indicates that the movement has been successfully queued. The LUN object can then be further polled with a GET request to /storage/luns/{uuid} to monitor the status of the movement.
The movement sub-object of the LUN object is populated while a LUN movement is in progress and for two minutes following completion of a movement.

Examples

Deleting a LUN

from netapp_ontap import HostConnection
from netapp_ontap.resources import Lun

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Lun(uuid="c903a978-9bac-4ce9-8237-4a3ba8b13f08")
    resource.delete()


Classes

class Lun (*args, **kwargs)

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.

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 count_collection(*args, connection: HostConnection = None, **kwargs) -> int

Fetch a count of all objects of this type from the host.

This calls GET on the object to determine the number of records. It is more efficient than calling get_collection() because it will not construct any objects. Query parameters can be passed in as kwargs to determine a count of objects that match some filtered criteria.

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 get the count 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. These query parameters can affect the count. A return_records query param will be ignored.

Returns

On success, returns an integer count of the objects of this type. On failure, returns -1.

Raises

NetAppRestError: If the API call returned a status code >= 400, or if there is no connection available to use either passed in or on the library.

def delete_collection(*args, records: Iterable[_ForwardRef('Lun')] = None, body: Union[Resource, dict] = None, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, connection: HostConnection = None, **kwargs) -> NetAppResponse

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.
records
Can be provided in place of a query. If so, this list of objects will be deleted from the host.
body
The body of the delete request. This could be a Resource instance or a dictionary object.
poll
If set to True, the call will not return until the asynchronous job on the host has completed. Has no effect if the host did not return a job response.
poll_interval
If the operation returns a job, this specifies how often to query the job for updates.
poll_timeout
If the operation returns a job, this specifies how long to continue monitoring the job's status for completion.
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 deleted.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

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

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, None will be returned. 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

Fetch a list of all objects of this type from the host.

This is a lazy fetch, making API calls only as necessary when the result of this call is iterated over. For instance, if max_records is set to 5, then iterating over the collection causes an API call to be sent to the server once for every 5 records. If the client stops iterating before getting to the 6th record, then no additional API calls are made.

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 get 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.
max_records
The maximum number of records to return per call
**kwargs
Any key/value pairs passed will be sent as query parameters to the host.

Returns

A list of Resource objects

Raises

NetAppRestError: If there is no connection available to use either passed in or on the library. This would be not be raised when get_collection() is called, but rather when the result is iterated.

The fields of the Lun object

Ancestors

  • netapp_ontap.resource.ResourceSchema
  • marshmallow.schema.Schema
  • marshmallow.base.SchemaABC

Class variables

attributes GET POST

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 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.

auto_delete GET POST PATCH

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 Requesting specific fields to learn more.

class_ GET POST

The class of LUN.
Optional in POST.

Valid choices:

  • regular
  • protocol_endpoint
  • vvol
clone POST PATCH

The clone field of the lun.

comment GET POST PATCH

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

consistency_group GET POST PATCH

The consistency_group field of the lun.

copy GET POST PATCH

The copy field of the lun.

create_time GET

The time the LUN was created.

Example: 2018-06-04T19:00:00.000+0000

enabled GET PATCH

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.

The links field of the lun.

location GET POST PATCH

The location field of the lun.

lun_maps GET

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 Requesting specific fields to learn more.

metric GET

The metric field of the lun.

movement GET POST PATCH

The movement field of the lun.

name GET POST PATCH

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.

Example: /vol/volume1/qtree1/lun1

os_type GET POST

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.
