DescribeVolumeStatus - Amazon Elastic Compute Cloud


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 EBS 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.)


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 Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.


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.

Type: Boolean

Required: No


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.
