# Compute Engine API . disks

## Instance Methods

Retrieves an aggregated list of persistent disks.

Retrieves the next page of results.

Creates a snapshot of a specified persistent disk.

Deletes the specified persistent disk. Deleting a disk removes its data permanently and is irreversible. However, deleting a disk does not delete any snapshots previously made from the disk. You must separately delete snapshots.

Returns a specified persistent disk. Get a list of available persistent disks by making a list() request.

Creates a persistent disk in the specified project using the data in the request. You can create a disk with a sourceImage, a sourceSnapshot, or create an empty 500 GB data disk by omitting all properties. You can also create a disk that is larger than the default size by specifying the sizeGb property.

Retrieves a list of persistent disks contained within the specified zone.

Retrieves the next page of results.

Resizes the specified persistent disk.

### Method Details

`aggregatedList(project, maxResults=None, pageToken=None, filter=None)`

    Retrieves an aggregated list of persistent disks.

    Args:
      project: string, Project ID for this request. (required)
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests.
      pageToken: string, Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
      filter: string, Sets a filter expression for filtering listed resources, in the form filter={expression}. Your {expression} must be in the format: field_name comparison_string literal_string.

    The field_name is the name of the field you want to compare. Only atomic field types are supported (string, number, boolean). The comparison_string must be either eq (equals) or ne (not equals). The literal_string is the string value to filter to. The literal value must be valid for the type of field you are filtering by (string, number, boolean). For string fields, the literal value is interpreted as a regular expression using RE2 syntax. The literal value must match the entire field.

    For example, to filter for instances that do not have a name of example-instance, you would use filter=name ne example-instance.

    Compute Engine Beta API Only: When filtering in the Beta API, you can also filter on nested fields. For example, you could filter on instances that have set the scheduling.automaticRestart field to true. Use filtering on nested fields to take advantage of labels to organize and search for results based on label values.

    The Beta API also supports filtering on multiple expressions by providing each separate expression within parentheses. For example, (scheduling.automaticRestart eq true) (zone eq us-central1-f). Multiple expressions are treated as AND expressions, meaning that resources must match all expressions to pass the filters.

    Returns:
      An object of the form:

        {
        "nextPageToken": "A String", # [Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger than maxResults, use the nextPageToken as a value for the query parameter pageToken in the next list request. Subsequent list requests will have their own nextPageToken to continue paging through the results.

`list(project, zone, maxResults=None, pageToken=None, filter=None)`

    Retrieves a list of persistent disks contained within the specified zone.

    Args:
      project: string, Project ID for this request. (required)
      zone: string, The name of the zone for this request. (required)
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests.
      pageToken: string, Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
      filter: string, Sets a filter expression for filtering listed resources, in the form filter={expression}. Your {expression} must be in the format: field_name comparison_string literal_string.

    The field_name is the name of the field you want to compare. Only atomic field types are supported (string, number, boolean). The comparison_string must be either eq (equals) or ne (not equals). The literal_string is the string value to filter to. The literal value must be valid for the type of field you are filtering by (string, number, boolean). For string fields, the literal value is interpreted as a regular expression using RE2 syntax. The literal value must match the entire field.

    For example, to filter for instances that do not have a name of example-instance, you would use filter=name ne example-instance.

    Compute Engine Beta API Only: When filtering in the Beta API, you can also filter on nested fields. For example, you could filter on instances that have set the scheduling.automaticRestart field to true. Use filtering on nested fields to take advantage of labels to organize and search for results based on label values.

    The Beta API also supports filtering on multiple expressions by providing each separate expression within parentheses. For example, (scheduling.automaticRestart eq true) (zone eq us-central1-f). Multiple expressions are treated as AND expressions, meaning that resources must match all expressions to pass the filters.

    Returns:
      An object of the form:

        "nextPageToken": "A String", # [Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger than maxResults, use the nextPageToken as a value for the query parameter pageToken in the next list request. Subsequent list requests will have their own nextPageToken to continue paging through the results.
