update-chap-credentials¶

Description¶

Updates the Challenge-Handshake Authentication Protocol (CHAP) credentials for a specified iSCSI target. By default, a gateway does not have CHAP enabled; however, for added security, you might use it. This operation is supported in the volume and tape gateway types.

Warning

When you update CHAP credentials, all existing connections on the target are closed and initiators must reconnect with the new credentials.

Synopsis¶

  update-chap-credentials
--target-arn <value>
--secret-to-authenticate-initiator <value>
--initiator-name <value>
[--secret-to-authenticate-target <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--target-arn (string)

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

--secret-to-authenticate-initiator (string)

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

Note

The secret key must be between 12 and 16 bytes when encoded in UTF-8.

--initiator-name (string)

The iSCSI initiator that connects to the target.

--secret-to-authenticate-target (string)

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

Byte constraints: Minimum bytes of 12. Maximum bytes of 16.

Note

The secret key must be between 12 and 16 bytes when encoded in UTF-8.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output¶

TargetARN -> (string)

The Amazon Resource Name (ARN) of the target. This is the same target specified in the request.

InitiatorName -> (string)

The iSCSI initiator that connects to the target. This is the same initiator name specified in the request.
