Updating storage aggregates

The PATCH operation is used to modify properties of the aggregate. There are several properties that can be modified on an aggregate. Only one property can be modified for each PATCH request. PATCH operations on the aggregate's disk count will be blocked while one or more nodes in the cluster are simulating or implementing automatic aggregate creation.
The following is a list of properties that can be modified using the PATCH operation including a brief description for each:

  • name - This property can be changed to rename the aggregate.
  • node.name and node.uuid - Either property can be updated in order to relocate the aggregate to a different node in the cluster.
  • block_storage.mirror.enabled - This property can be changed from 'false' to 'true' in order to mirror the aggregate, if the system is capable of doing so.
  • block_storage.primary.disk_count - This property can be updated to increase the number of disks in an aggregate.
  • block_storage.primary.raid_size - This property can be updated to set the desired RAID size.
  • block_storage.primary.raid_type - This property can be updated to set the desired RAID type.
  • cloud_storage.tiering_fullness_threshold - This property can be updated to set the desired tiering fullness threshold if using FabricPool.
  • data_encryption.software_encryption_enabled - This property enables or disables NAE on the aggregate.

Aggregate expansion

The PATCH operation also supports automatically expanding an aggregate based on the spare disks which are present within the system. Running PATCH with the query "auto_provision_policy" set to "expand" starts the recommended expansion job. In order to see the expected change in capacity before starting the job, call GET on an aggregate instance with the query "auto_provision_policy" set to "expand".

Manual simulated aggregate expansion

The PATCH operation also supports simulated manual expansion of an aggregate. Running PATCH with the query "simulate" set to "true" and "block_storage.primary.disk_count" set to the final disk count will start running the prechecks associated with expanding the aggregate to the proposed size. The response body will include information on how many disks the aggregate can be expanded to, any associated warnings, along with the proposed final size of the aggregate.

Deleting storage aggregates

If volumes exist on an aggregate, they must be deleted or moved before the aggregate can be deleted. See the /storage/volumes API for details on moving or deleting volumes.


Examples

Retrieving a specific aggregate from the cluster

The following example shows the response of the requested aggregate. If there is no aggregate with the requested UUID, an error is returned.

Simulating aggregate expansion

The following example shows the response for a simulated data aggregate expansion based on the values of the 'block_storage.primary.disk_count' attribute passed in. The query does not modify the existing aggregate but returns how the aggregate will look after the expansion along with any associated warnings. Simulated data aggregate expansion will be blocked while one or more nodes in the cluster are simulating or implementing automatic aggregate creation. This will be reflected in the following attributes:

  • space.block_storage.size - Total usable space in bytes, not including WAFL reserve and aggregate Snapshot copy reserve.
  • block_storage.primary.disk_count - Number of disks that could be used to create the aggregate.
from netapp_ontap import HostConnection
from netapp_ontap.resources import Aggregate

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Aggregate(uuid="cae60cfe-deae-42bd-babb-ef437d118314")
    resource.block_storage.primary.disk_count = 14
    resource.patch(hydrate=True, simulate=True)

Retrieving a recommendation for an aggregate expansion

The following example shows the response with the recommended data aggregate expansion based on what disks are present within the system. The query does not modify the existing aggregate but returns how the aggregate will look after the expansion. The recommendation will be reflected in the attributes - 'space.block_storage.size' and 'block_storage.primary.disk_count'. Recommended data aggregate expansion will be blocked while one or more nodes in the cluster are simulating or implementing automatic aggregate creation.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Aggregate

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Aggregate(uuid="cae60cfe-deae-42bd-babb-ef437d118314")
    resource.get(auto_provision_policy="expand")
    print(resource)

Aggregate(
    {
        "block_storage": {
            "hybrid_cache": {"enabled": False},
            "mirror": {"enabled": False},
            "primary": {
                "disk_class": "solid_state",

            }
        },
        "name": "node_2_SSD_1",
        "node": {
            "uuid": "4046dda8-f802-11e8-8f6d-005056bb2030",

                }
            },
        },
    }
)

Updating an aggregate in the cluster

The following example shows the workflow of adding disks to the aggregate.
Step 1: Check the current disk count on the aggregate.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Aggregate

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Aggregate(uuid="19425837-f2fa-4a9f-8f01-712f626c983c")
    resource.get(fields="block_storage.primary.disk_count")
    print(resource)

Aggregate(
    {
        "block_storage": {"primary": {"disk_count": 6}},
        "uuid": "19425837-f2fa-4a9f-8f01-712f626c983c",
        "name": "test1",
    }
)

Step 2: Update the aggregate with the new disk count in 'block_storage.primary.disk_count'. The response to PATCH is a job unless the request is invalid.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Aggregate

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Aggregate(uuid="19425837-f2fa-4a9f-8f01-712f626c983c")
    resource.block_storage.primary.disk_count = 8
    resource.patch()

Step 3: Wait for the job to finish, then call GET to see the reflected change.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Aggregate

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Aggregate(uuid="19425837-f2fa-4a9f-8f01-712f626c983c")
    resource.get(fields="block_storage.primary.disk_count")
    print(resource)

Aggregate(
    {
        "block_storage": {"primary": {"disk_count": 8}},
        "uuid": "19425837-f2fa-4a9f-8f01-712f626c983c",
        "name": "test1",
    }
)

The following example shows the workflow to enable software encryption on an aggregate.
Step 1: Check the current software encryption status of the aggregate.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Aggregate

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Aggregate(uuid="f3aafdc6-be35-4d93-9590-5a402bffbe4b")
    resource.get(fields="data_encryption.software_encryption_enabled")
    print(resource)

Aggregate(
    {
        "data_encryption": {"software_encryption_enabled": False},
        "uuid": "f3aafdc6-be35-4d93-9590-5a402bffbe4b",
        "name": "aggr5",
    }
)

Step 2: Update the aggregate with the encryption status in 'data_encryption.software_encryption_enabled'. The response to PATCH is a job unless the request is invalid.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Aggregate

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Aggregate(uuid="f3aafdc6-be35-4d93-9590-5a402bffbe4b")
    resource.data_encryption.software_encryption_enabled = True
    resource.patch()

Step 3: Wait for the job to finish, then call GET to see the reflected change.

from netapp_ontap import HostConnection
from netapp_ontap.resources import Aggregate

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Aggregate(uuid="f3aafdc6-be35-4d93-9590-5a402bffbe4b")
    resource.get(fields="data_encryption.software_encryption_enabled")
    print(resource)

Aggregate(
    {
        "data_encryption": {"software_encryption_enabled": True},
        "uuid": "f3aafdc6-be35-4d93-9590-5a402bffbe4b",
        "name": "aggr5",
    }
)

Classes

class Aggregate (*args, **kwargs)

Allows interaction with Aggregate 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

Retrieves the collection of aggregates for the entire cluster.

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. See Requesting specific fields to learn more. * metric.* * space.block_storage.inactive_user_data * space.footprint * statistics.*

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 the aggregate specified by the UUID. This request starts a job and returns a link to that job.

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 deleted.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

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) -> typing.Iterable

Retrieves the collection of aggregates for the entire cluster.

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. See Requesting specific fields to learn more. * metric.* * space.block_storage.inactive_user_data * space.footprint * statistics.*

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 patch_collection(body: dict, *args, connection: HostConnection = None, **kwargs) -> NetAppResponse

Updates the aggregate specified by the UUID with the properties in the body. This request starts a job and returns a link to that job.

Send the difference in the object's state to the host as a modification request.

Calculates the difference in the object's state since the last time we interacted with the host and sends this in the request body.

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

def post(self, hydrate: bool = False, poll: bool = True, poll_interval: typing.Union = None, poll_timeout: typing.Union = None, **kwargs) -> NetAppResponse

Automatically creates aggregates based on an optimal layout recommended by the system. Alternatively, properties can be provided to create an aggregate according to the requested specification. This request starts a job and returns a link to that job. POST operations will be blocked while one or more nodes in the cluster are simulating or implementing automatic aggregate creation.

Required properties

Properties are not required for this API. The following properties are only required if you want to specify properties for aggregate creation: * name - Name of the aggregate. * node.name or node.uuid - Node on which the aggregate will be created. * block_storage.primary.disk_count - Number of disks to be used to create the aggregate.

Default values

If not specified in POST, the following default values are assigned. The remaining unspecified properties will receive system dependent default values. * block_storage.mirror.enabled - false * snaplock_type - non_snaplock

  • storage aggregate auto-provision
  • storage aggregate create

Example:

POST /api/storage/aggregates {"node": {"name": "node1"}, "name": "test", "block_storage": {"primary": {"disk_count": "10"}}}
