[ aws . storagegateway ]

describe-vtl-devices

Description

Returns a description of virtual tape library (VTL) devices for the specified tape gateway. In the response, Storage Gateway returns VTL device information.

This operation is only supported in the tape gateway type.

See also: AWS API Documentation

describe-vtl-devices 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: VTLDevices

Options

--gateway-arn (string)

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

--vtl-device-arns (list)

An array of strings, where each string represents the Amazon Resource Name (ARN) of a VTL device.

Note

All of the specified VTL devices must be from the same gateway. If no VTL devices are specified, the result will contain all devices on the specified gateway.

(string)

Syntax:

"string" "string" ...

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Output

GatewayARN -> (string)

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

VTLDevices -> (list)

An array of VTL device objects composed of the Amazon Resource Name (ARN) of the VTL devices.

(structure)

Represents a device object associated with a tape gateway.

VTLDeviceARN -> (string)

Specifies the unique Amazon Resource Name (ARN) of the device (tape drive or media changer).

VTLDeviceType -> (string)

Specifies the type of device that the VTL device emulates.

VTLDeviceVendor -> (string)

Specifies the vendor of the device that the VTL device object emulates.

VTLDeviceProductIdentifier -> (string)

Specifies the model number of device that the VTL device emulates.

DeviceiSCSIAttributes -> (structure)

A list of iSCSI information about a VTL device.

TargetARN -> (string)

Specifies the unique Amazon Resource Name (ARN) that encodes the iSCSI qualified name(iqn) of a tape drive or media changer target.

NetworkInterfaceId -> (string)

The network interface identifier of the VTL device.

NetworkInterfacePort -> (integer)

The port used to communicate with iSCSI VTL device targets.

ChapEnabled -> (boolean)

Indicates whether mutual CHAP is enabled for the iSCSI target.

Marker -> (string)

An opaque string that indicates the position at which the VTL devices that were fetched for description ended. Use the marker in your next request to fetch the next set of VTL devices in the list. If there are no more VTL devices to describe, this field does not appear in the response.
