ListVolumes

Lists the iSCSI stored volumes of a gateway. Results are sorted by volume ARN. The response includes only the volume ARNs. If you want additional volume information, use the DescribeStorediSCSIVolumes or the DescribeCachediSCSIVolumes API.

The operation supports pagination. By default, the operation returns a maximum of up to 100 volumes. You can optionally specify the Limit field in the body to limit the number of volumes in the response. If the number of volumes returned in the response is truncated, the response includes a Marker field. You can use this Marker value in your subsequent request to retrieve the next set of volumes. This operation is only supported in the cached volume and stored volume gateway types.

Marker

Use the marker in your next request to continue pagination of iSCSI volumes. If there are no more volumes to list, this field does not appear in the response body.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1000.

VolumeInfos

An array of VolumeInfo objects, where each object describes an iSCSI volume. If no volumes are defined for the gateway, then VolumeInfos is an empty array "[]".

Type: Array of VolumeInfo objects
