Overview
An NVMe subsystem map is an association of an NVMe namespace with an NVMe subsystem. When an NVMe namespace is mapped to an NVMe subsystem, the NVMe subsystem's hosts are granted access to the NVMe namespace. The relationship between an NVMe subsystem and an NVMe namespace is one subsystem to many namespaces.
The NVMe subsystem map REST API allows you to create, delete and discover NVMe subsystem maps.
Examples
Creating an NVMe subsystem map

Retrieving a specific NVMe subsystem map
The NVMe subsystem map is identified by the UUID of the NVMe subsystem followed by the UUID of the NVMe namespace.

Classes
class NvmeSubsystemMap (*args, **kwargs)
-
An NVMe subsystem map is an association of an NVMe namespace with an NVMe subsystem. When an NVMe namespace is mapped to an NVMe subsystem, the NVMe subsystem's hosts are granted access to the NVMe namespace. The relationship between an NVMe subsystem and an NVMe namespace is one subsystem to many namespaces.
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
-
Retrieves NVMe subsystem maps.
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. SeeDOC Requesting specific fields
to learn more. *anagrpid
Related ONTAP commands
vserver nvme subsystem map show
Learn more
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, body: typing.Union = None, connection: HostConnection = None, **kwargs) -> NetAppResponse
-
Deletes an NVMe subsystem map.

Learn more
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.
body
- The body of the delete request. This could be a Resource instance or a dictionary object.
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

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.

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
objectsRaises
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.
