DescribeVolumes

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

If you are describing a long list of volumes, you can paginate the output to make the list more manageable. The MaxResults parameter sets the maximum number of results returned in a single page. If the list of results exceeds your MaxResults value, then that number of results is returned along with a NextToken value that can be passed to a subsequent DescribeVolumes request to retrieve the remaining results.

For more information about EBS volumes, see Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide.

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.

DryRun

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

Filter.N

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)

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

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

  • status - The status 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. This can be gp2 for General Purpose SSD, io1 for Provisioned IOPS SSD, st1 for Throughput Optimized HDD, sc1 for Cold HDD, or standard for Magnetic volumes.

Type: Array of Filter objects

Required: No

MaxResults

The maximum number of volume results returned by DescribeVolumes in paginated output. When this parameter is used, DescribeVolumes only returns MaxResults results in a single page along with a NextToken response element. The remaining results of the initial request can be seen by sending another DescribeVolumes request with the returned NextToken value. This value can be between 5 and 500; if MaxResults is given a value larger than 500, only 500 results are returned. If this parameter is not used, then DescribeVolumes returns all results. You cannot specify this parameter and the volume IDs parameter in the same request.

Type: Integer

Required: No

NextToken

The NextToken value returned from a previous paginated DescribeVolumes request where MaxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the NextToken value. This value is null when there are no more results to return.

Type: String

Required: No

VolumeId.N

The volume IDs.

Type: Array of strings

Required: No

Response Elements

The following elements are returned by the service.

nextToken

The NextToken value to include in a future DescribeVolumes request. When the results of a DescribeVolumes request exceed MaxResults, this value can be used to retrieve the next page of results. This value is null when there are no more results to return.

Type: String

requestId

The ID of the request.

Type: String

volumeSet

Information about the volumes.

Type: Array of Volume objects

Errors

For information about the errors that are common to all actions, see Common Client Errors.
