describe_status

describe_status(**kwargs)

Describes the status of the specified volumes. Volume status provides the result of the checks performed on your volumes to determine events that can impair the performance of your volumes. The performance of a volume can be affected if an issue occurs on the volume's underlying host. If the volume's underlying host experiences a power outage or system issue, after the system is restored, there could be data inconsistencies on the volume. Volume events notify you if this occurs. Volume actions notify you if any action needs to be taken in response to the event.

The DescribeVolumeStatus operation provides the following information about the specified volumes:

Status : Reflects the current status of the volume. The possible values are ok , impaired , warning , or insufficient-data . If all checks pass, the overall status of the volume is ok . If the check fails, the overall status is impaired . If the status is insufficient-data , then the checks might still be taking place on your volume at the time. We recommend that you retry the request. For more information about volume status, see Monitor the status of your volumes in the Amazon Elastic Compute Cloud User Guide .

Events : Reflect the cause of a volume status and might require you to take action. For example, if your volume returns an impaired status, then the volume event might be potential-data-inconsistency . This means that your volume has been affected by an issue with the underlying host, has all I/O operations disabled, and might have inconsistent data.

Actions : Reflect the actions you might have to take in response to an event. For example, if the status of the volume is impaired and the volume event shows potential-data-inconsistency , then the action shows enable-volume-io . This means that you may want to enable the I/O operations for the volume by calling the EnableVolumeIO action and then check the volume for data consistency.

Volume status is based on the volume status checks, and does not reflect the volume state. Therefore, volume status does not indicate volumes in the error state (for example, when a volume is incapable of accepting I/O.)

Request Syntax

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

Parameters

• Filters (list) --

  The filters.

  • action.code - The action code for the event (for example, enable-volume-io ).
  • action.description - A description of the action.
  • action.event-id - The event ID associated with the action.
  • availability-zone - The Availability Zone of the instance.
  • event.description - A description of the event.
  • event.event-id - The event ID.
  • event.event-type - The event type (for io-enabled : passed | failed ; for io-performance : io-performance:degraded | io-performance:severely-degraded | io-performance:stalled ).
  • event.not-after - The latest end time for the event.
  • event.not-before - The earliest start time for the event.
  • volume-status.details-name - The cause for volume-status.status ( io-enabled | io-performance ).
  • volume-status.details-status - The status of volume-status.details-name (for io-enabled : passed | failed ; for io-performance : normal | degraded | severely-degraded | stalled ).
  • volume-status.status - The status of the volume ( ok | impaired | warning | insufficient-data ).
  • (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) --
• 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. This value can be between 5 and 1,000; if the value is larger than 1,000, only 1,000 results are returned. If this parameter is not used, then all items are returned. You cannot specify this parameter and the volume IDs parameter in the same request. For more information, see Pagination.
• NextToken (string) -- The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.
• 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 .
