Overview

A portset is a collection of Fibre Channel Protocol and/or iSCSI network interfaces from the portset's SVM.
Portsets are used to limit the network interfaces through which an initiator can connect to mapped LUNs. When a portset is bound to an initiator group (igroup), and the initiator group is mapped to a LUN, the initiators of the initiator group can only reach the LUN through the network interfaces in the portset.
Portsets are not recommended for new configurations. With modern releases of ONTAP, it is recommended to use multiple SVMs and initiator groups with no bound portset to load balance applications over multiple ports on a node. Selective LUN mapping will automatically limit the number of visible paths to a LUN from the client host to those required for efficient access and high availability. The REST portset API is primarily intended for legacy use.
The portset REST API allows you to create, delete, and discover portsets, and to add and remove network interaces from portsets.
A portset can be bound to one or more initiator groups. An initiator group (igroup) can be bound to at most one portset.
When a portset is created, the protocol property is used to restrict member network interfaces to Fibre Channel Procotol (fcp), iSCSI (iscsi), or both (mixed).
Zero or more network interfaces can be supplied when the portset is created. After creation, network interfaces can be added to or removed from the portset using the /protocols/san/portsets/{portset.uuid}/interfaces endpoint. See POST /protocols/san/portsets/{portset.uuid}/interfaces and DELETE /protocols/san/portsets/{portset.uuid}/interfaces/{name} for more details.

Examples

Creating a portset with no network interfaces

The example portset uses the default mixed protocol. Note that the return_records query parameter is used to obtain the newly created portset in the response.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Portset

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Portset()
    resource.svm = {"name": "svm1"}
    resource.name = "portset1"
    resource.post(hydrate=True)
    print(resource)

Portset(
    {
        "svm": {
            "_links": {
                "self": {"href": "/api/svm/svms/31484775-1e23-11eb-b2a8-005056bb3521"}
            },
            "uuid": "31484775-1e23-11eb-b2a8-005056bb3521",
            "name": "svm1",
        },

            }
        },
    }

Creating an iSCSI portset with two network interfaces

Note that the return_records query parameter is used to obtain the newly created portset in the response.

    resource.protocol = "iscsi"
    resource.interfaces = [{"ip": {"name": "lif1"}}, {"ip": {"name": "lif2"}}]
    resource.post(hydrate=True)
    print(resource)

Classes

class Portset (*args, **kwargs)

Allows interaction with Portset 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 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('Portset')] = 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

Deletes a portset.

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.
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

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

Retrieves portsets.

  • lun portset show

Learn more


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
Any key/value pairs passed will be sent as query parameters to the host.

Returns

A Resource object containing the details of the object or None if no matches were found.

Raises

NetAppRestError: If the API call returned more than 1 matching resource.

def get_collection(*args, connection: HostConnection = None, max_records: int = None, **kwargs) -> Iterable[Resource]

Retrieves portsets.

  • lun portset show

Learn more


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.

def post_collection(records: Iterable[_ForwardRef('Portset')], *args, hydrate: bool = False, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, connection: HostConnection = None, **kwargs) -> Union[List[Portset], NetAppResponse]

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 list of Resource objects matching the provided
type which have been created by the host and returned. This is _not_
 
the same list that was provided, so to continue using the object, you
 

should save this list. If poll is set to False, then a NetAppResponse object is returned instead.

Raises

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

Methods

def delete(self, body: Union[Resource, dict] = None, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, **kwargs) -> NetAppResponse

Deletes a portset.

Send a deletion request to the host for this object.

Args

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.
**kwargs
Any key/value pairs passed will be sent as query parameters to the host.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

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

def get(self, **kwargs) -> NetAppResponse

Retrieves a portset.

  • lun portset show

Fetch the details of the object from the host.

Requires the keys to be set (if any). After returning, new or changed properties from the host will be set on the instance.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

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

def post(self, hydrate: bool = False, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, **kwargs) -> NetAppResponse

Creates a portset.

Required properties

  • svm.uuid or svm.name - Existing SVM in which to create the portset.
  • name - Name of the portset.
  • protocol - The network protocol of the interfaces in the portset.
  • interfaces - Network interfaces to include in the portset. This property can be used to create the portset and populate it with network interfaces in a single request.

Default property values

If not specified in POST, the following default property values are assigned. * protocol - mixed - Data protocol of the portset's network interfaces.

  • lun portset create

Send this object to the host as a creation request.

Args

hydrate
If set to True, after the response is received from the call, a a GET call will be made to refresh all fields of the 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.
**kwargs
Any key/value pairs passed will normally be sent as query parameters to the host. If any of these pairs are parameters that are sent as formdata then only parameters of that type will be accepted and all others will be discarded.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

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

The fields of the Portset object

Ancestors

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

Class variables

igroups GET

An array initiator groups to which the portset is bound.

interfaces GET POST

An array of network interfaces that are members of the portset. These are the only network interfaces through which the initiators of a bound igroup can access mapped LUNs.
Zero or more network interfaces can be supplied when the portset is created. After creation, network interfaces can be added or removed from the portset using the /protocols/san/portsets/{portset.uuid}/interfaces endpoint. See POST /protocols/san/portsets/{portset.uuid}/interfaces and DELETE /protocols/san/portsets/{portset.uuid}/interfaces/{uuid} for more details.

The links field of the portset.

name GET POST

The name of the portset. Required in POST.
The name of a portset cannot be changed after creation.

Example: portset1

protocol GET POST

The protocols supported by the portset. This restricts the type of network interfaces that can be added to the portset. Optional in POST; if not supplied, this defaults to mixed.
The protocol of a portset cannot be changed after creation.

Valid choices:

  • fcp
  • iscsi
  • mixed
svm GET POST

The svm field of the portset.

uuid GET

The unique identifier for a portset.

Example: 1cd8a442-86d1-11e0-ae1c-123478563412
