AttachVolume

Connects a volume to an iSCSI connection and then attaches the volume to the specified gateway. Detaching and attaching a volume enables you to recover your data from one gateway to a different gateway without creating a snapshot. It also makes it easier to move your volumes from an on-premises gateway to a gateway hosted on an Amazon EC2 instance.

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 device ID or other distinguishing data that identifies the local disk used to create the volume. This value is only required when you are attaching a stored volume.

Type: String

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

Required: No

GatewayARN

The Amazon Resource Name (ARN) of the gateway that you want to attach the volume to.

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

TargetName

The name of the iSCSI target used by an initiator to connect to a volume and used 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 on a gateway.

If you don't specify a value, Storage Gateway uses the value that was previously used for this volume as the new target name.

Type: String

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

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

Required: No

VolumeARN

The Amazon Resource Name (ARN) of the volume to attach to the specified gateway.

Type: String

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

Pattern: arn:(aws(|-cn|-us-gov|-iso[A-Za-z0-9_-]*)):storagegateway:[a-z\-0-9]+:[0-9]+:gateway\/(.+)\/volume\/vol-(\S+)

Required: Yes

VolumeARN

The Amazon Resource Name (ARN) of the volume that was attached to the gateway.

Type: String

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

Pattern: arn:(aws(|-cn|-us-gov|-iso[A-Za-z0-9_-]*)):storagegateway:[a-z\-0-9]+:[0-9]+:gateway\/(.+)\/volume\/vol-(\S+)
