describe_volumes

EC2.Client.describe_volumes(**kwargs)

Describes the specified EBS volumes or all of your EBS volumes.

If you are describing a long list of volumes, we recommend that you paginate the output to make the list more manageable. For more information, see Pagination.

For more information about EBS volumes, see Amazon EBS volumes in the Amazon EBS User Guide.

Warning

We strongly recommend using only paginated requests. Unpaginated requests are susceptible to throttling and timeouts.

Note

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

Request Syntax

response = client.describe_volumes(
    VolumeIds=[
        'string',
    ],
    DryRun=True|False,
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    NextToken='string',
    MaxResults=123
)

Parameters:

• VolumeIds (list) –

  The volume IDs. If not specified, then all volumes are included in the response.

  • (string) –

• DryRun (boolean) – Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

• Filters (list) –

  The filters.

  • attachment.attach-time - The time stamp when the attachment initiated.

  • attachment.delete-on-termination - Whether the volume is deleted on instance termination.

  • attachment.device - The device name specified in the block device mapping (for example, /dev/sda1).

  • attachment.instance-id - The ID of the instance the volume is attached to.

  • attachment.status - The attachment state ( attaching | attached | detaching).

  • availability-zone - The Availability Zone in which the volume was created.

  • create-time - The time stamp when the volume was created.

  • encrypted - Indicates whether the volume is encrypted ( true | false)

  • multi-attach-enabled - Indicates whether the volume is enabled for Multi-Attach ( true | false)

  • fast-restored - Indicates whether the volume was created from a snapshot that is enabled for fast snapshot restore ( true | false).

  • size - The size of the volume, in GiB.

  • snapshot-id - The snapshot from which the volume was created.

  • status - The state of the volume ( creating | available | in-use | deleting | deleted | error).

  • tag:<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.

  • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

  • volume-id - The volume ID.

  • volume-type - The Amazon EBS volume type ( gp2 | gp3 | io1 | io2 | st1 | sc1``| ``standard)

  • (dict) –

    A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.

    If you specify multiple filters, the filters are joined with an AND, and the request returns only results that match all of the specified filters.

    • Name (string) –

      The name of the filter. Filter names are case-sensitive.

    • Values (list) –

      The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR, and the request returns all results that match any of the specified values.

      • (string) –

• NextToken (string) – The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.

• MaxResults (integer) – The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. For more information, see Pagination.
