AWS Storage Gateway Service
API Reference (API Version 2013-06-30)

CreateStorediSCSIVolume

Creates a volume on a specified gateway. This operation is only supported in the stored volume gateway type.

The size of the volume to create is inferred from the disk size. You can choose to preserve existing data on the disk, create volume from an existing snapshot, or create an empty volume. If you choose to create an empty gateway volume, then any existing data on the disk is erased.

In the request you must specify the gateway and the disk information on which you are creating the volume. In response, the gateway creates the volume and returns volume information such as the volume Amazon Resource Name (ARN), its size, and the iSCSI target ARN that initiators can use to connect to the volume target.

Request Syntax

{
   "DiskId": "string",
   "GatewayARN": "string",
   "NetworkInterfaceId": "string",
   "PreserveExistingData": boolean,
   "SnapshotId": "string",
   "TargetName": "string"
}

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

DiskId

The unique identifier for the gateway local disk that is configured as a stored volume. Use ListLocalDisks to list disk IDs for a gateway.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 300.

Required: Yes

GatewayARN

The Amazon Resource Name (ARN) of the gateway. Use the ListGateways operation to return a list of gateways for your account and region.

Type: String

Length Constraints: Minimum length of 50. Maximum length of 500.

Required: Yes

NetworkInterfaceId

The network interface of the gateway on which to expose the iSCSI target. Only IPv4 addresses are accepted. Use DescribeGatewayInformation to get a list of the network interfaces available on a gateway.

Valid Values: A valid IP address.

Type: String

Pattern: \A(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\z

Required: Yes

PreserveExistingData

Specify this field as true if you want to preserve the data on the local disk. Otherwise, specifying this field as false creates an empty volume.

Valid Values: true, false

Type: Boolean

Required: Yes

SnapshotId

The snapshot ID (e.g. "snap-1122aabb") of the snapshot to restore as the new stored volume. Specify this field if you want to create the iSCSI storage volume from a snapshot otherwise do not include this field. To list snapshots for your account use DescribeSnapshots in the Amazon Elastic Compute Cloud API Reference.

Type: String

Pattern: \Asnap-([0-9A-Fa-f]{8}|[0-9A-Fa-f]{17})\z

Required: No

TargetName

The name of the iSCSI target used by initiators to connect to the target and as a suffix for the target ARN. For example, specifying TargetName as myvolume results in the target ARN of arn:aws:storagegateway:us-east-2:111122223333:gateway/sgw-12A3456B/target/iqn.1997-05.com.amazon:myvolume. The target name must be unique across all volumes of a gateway.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 200.

Pattern: ^[-\.;a-z0-9]+$

Required: Yes

Response Syntax

{
   "TargetARN": "string",
   "VolumeARN": "string",
   "VolumeSizeInBytes": number
}

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

TargetARN

he Amazon Resource Name (ARN) of the volume target that includes the iSCSI name that initiators can use to connect to the target.

Type: String

Length Constraints: Minimum length of 50. Maximum length of 800.

VolumeARN

The Amazon Resource Name (ARN) of the configured volume.

Type: String

Length Constraints: Minimum length of 50. Maximum length of 500.

VolumeSizeInBytes

The size of the volume in bytes.

Type: Long

Errors

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

InternalServerError

An internal server error has occurred during the request. For more information, see the error and message fields.

HTTP Status Code: 400

InvalidGatewayRequestException

An exception occurred because an invalid gateway request was issued to the service. For more information, see the error and message fields.

HTTP Status Code: 400
