Retrieving storage disk information

The storage disk GET API retrieves all of the disks in the cluster.


Examples

1) Retrieve a list of disks from the cluster.

The following example shows the response with a list of disks in the cluster:


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    print(list(Disk.get_collection()))

[
    Disk({"name": "1.24.4"}),
    Disk({"name": "1.24.3"}),
    Disk({"name": "1.24.5"}),
    Disk({"name": "1.24.0"}),
    Disk({"name": "1.24.2"}),
    Disk({"name": "1.24.1"}),
]


2) Retrieve a specific disk from the cluster.

The following example shows the response of the requested disk. If there is no disk with the requested name, an error is returned:


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Disk(name="1.24.3")
    resource.get()
    print(resource)

Modifying storage disk

The storage disk PATCH API modifies disk ownership, unfails a disk, or updates encrypting drive authentication keys (AKs) in the cluster. The storage disk API currently supports patching one attribute at a time.

Updating the disk ownership for a specified disk

1. When the disk is not assigned

When the disk is a spare (or unowned) disk and node name is specified, the PATCH operation assigns the disk to the specified node. Optionally, pool name can also be specified along with node name. Accepted pool names are: pool0, pool1.

2. When the disk is already assigned

When the disk is already assigned (already has a owner), and a new node is specified, the PATCH operation changes the ownership to the new node. Optionally, pool name can also be specified along with node name. Accepted pool names are: pool0, pool1.

Removing the disk ownership for a specified disk

When the disk is already assigned, and node name is specified as null (no-quotes), the PATCH operation removes the owner.


Examples

1. Update the disk ownership for an unowned disk


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Disk()
    resource.node = {"name": "node-name"}
    resource.patch(hydrate=True, name="<disk-name>")


2. Update the disk ownership for an already owned disk


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Disk()
    resource.node = {"name": "node-name"}
    resource.patch(hydrate=True, name="<disk-name>")


3. Update the disk pool for a disk (can be either owned or unowned).


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Disk()
    resource.node = {"name": "node-name"}
    resource.pool = "pool0"
    resource.patch(hydrate=True, name="<disk-name>")


4. Rekey the data authentication key (AK) of all encrypting drives to an authentication key (AK) selected automatically by the system


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Disk()
    resource.patch(hydrate=True, name="*", encryption_operation="rekey_data_auto_id")


5. Cryptographically sanitize a spare or broken disk


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Disk()
    resource.patch(
        hydrate=True, name="<disk-name>", encryption_operation="sanitize_disk"
    )


6. Unfailing a disk to a spare.


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Disk()
    resource.state = "spare"
    resource.patch(hydrate=True, name="<disk-name>")


7. Unfailing a disk and attempting to reassimilate filesystem labels.

If unable or unnecessary to reassimilate filesystem labels, the disk will be set as spare.


from netapp_ontap import HostConnection
from netapp_ontap.resources import Disk

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = Disk()
    resource.state = "present"
    resource.patch(hydrate=True, name="<disk-name>")


Classes

class Disk (*args, **kwargs)

Allows interaction with Disk 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

Returns a count of all Disk resources that match the provided query


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

Retrieves a collection of disks.

  • storage disk 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 a collection of disks.

  • storage disk 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 patch_collection (body: dict, *args, records: Iterable[_ForwardRef('Disk')] = None, poll: bool = True, poll_interval: Optional[int] = None, poll_timeout: Optional[int] = None, connection: HostConnection = None, **kwargs) -> NetAppResponse

Updates disk ownership, changes authentication keys, or sanitizes disks.

  • storage disk assign
  • storage disk removeowner
  • storage encryption disk modify -data-key-id
  • storage encryption disk sanitize
  • security key-manager key query -key-type NSE-AK
  • storage disk unfail

Learn more


Patch all objects in a collection which match the given query.

All records on the host which match the query will be patched with the provided body.

Args

body
A dictionary of name/value pairs to set on all matching members of the collection. The body argument will be ignored if records is provided.
*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 patch 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 patched on the host.
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 patched.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

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

Methods

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

Retrieves a specific disk.

  • storage disk 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
