Options

--target-arn (string)

The Amazon Resource Name (ARN) of the iSCSI volume target. Use the DescribeStorediSCSIVolumes operation to return to retrieve the TargetARN for specified VolumeARN.

--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.

--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

ChapCredentials -> (list)

An array of ChapInfo objects that represent CHAP credentials. Each object in the array contains CHAP credential information for one target-initiator pair. If no CHAP credentials are set, an empty array is returned. CHAP credential information is provided in a JSON object with the following fields:

  • InitiatorName : The iSCSI initiator that connects to the target.
  • SecretToAuthenticateInitiator : The secret key that the initiator (for example, the Windows client) must provide to participate in mutual CHAP with the target.
  • SecretToAuthenticateTarget : The secret key that the target must provide to participate in mutual CHAP with the initiator (e.g. Windows client).
  • TargetARN : The Amazon Resource Name (ARN) of the storage volume.

(structure)

Describes Challenge-Handshake Authentication Protocol (CHAP) information that supports authentication between your gateway and iSCSI initiators.

TargetARN -> (string)

The Amazon Resource Name (ARN) of the volume.

Valid Values: 50 to 500 lowercase letters, numbers, periods (.), and hyphens (-).

SecretToAuthenticateInitiator -> (string)

The secret key that the initiator (for example, the Windows client) must provide to participate in mutual CHAP with the target.

InitiatorName -> (string)

The iSCSI initiator that connects to the target.

SecretToAuthenticateTarget -> (string)

The secret key that the target must provide to participate in mutual CHAP with the initiator (e.g., Windows client).
