describe-volume-status

Description

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 describe-volume-status 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 may still be taking place on your volume at the time. We recommend that you retry the request. For more information on volume status, see Monitoring the Status of Your Volumes .

Events : Reflect the cause of a volume status and may 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 may have inconsistent data.

Actions : Reflect the actions you may 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 enable-volume-io action and then check the volume for data consistency.

Note

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.)

See also: AWS API Documentation

describe-volume-status is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: VolumeStatuses

Options

--filters (list)

One or more 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 ).

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--volume-ids (list)

One or more volume IDs.

Default: Describes all your volumes.

Syntax:

"string" "string" ...

--dry-run | --no-dry-run (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 .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To describe the status of a single volume

This example command describes the status for the volume vol-1234567890abcdef0.

Command:

aws ec2 describe-volume-status --volume-ids vol-1234567890abcdef0

Output:

{
    "VolumeStatuses": [
        {
            "VolumeStatus": {
                "Status": "ok",
                "Details": [
                    {
                        "Status": "passed",
                        "Name": "io-enabled"
                    },
                    {
                        "Status": "not-applicable",
                        "Name": "io-performance"
                    }
                ]
            },
            "AvailabilityZone": "us-east-1a",
            "VolumeId": "vol-1234567890abcdef0",
            "Actions": [],
            "Events": []
        }
    ]
}

To describe the status of impaired volumes

This example command describes the status for all volumes that are impaired. In this example output, there are no impaired volumes.

Command:

aws ec2 describe-volume-status --filters Name=volume-status.status,Values=impaired

Output:

{
    "VolumeStatuses": []
}

If you have a volume with a failed status check (status is impaired), see Working with an Impaired Volume in the Amazon EC2 User Guide.
