docs: // CreateCachediSCSIVolume API operation for AWS Storage Gateway.
  //
  // Creates a cached volume on a specified cached volume gateway. This operation
  // is only supported in the cached volume gateway type.
  //
  // Cache storage must be allocated to the gateway before you can create a cached
  // volume. Use the AddCache operation to add cache storage to a gateway.
  //
  // In the request, you must specify the gateway, size of the volume in bytes,
  // the iSCSI target name, an IP address on which to expose the target, and a
  // unique client token. In response, the gateway creates the volume and returns
  // information about it. This information includes the volume Amazon Resource
  // Name (ARN), its size, and the iSCSI target ARN that initiators can use to
  // connect to the volume target.
  //
  // Optionally, you can provide the ARN for an existing volume as the SourceVolumeARN
  // for this cached volume, which creates an exact copy of the existing volume’s
  // latest recovery point. The VolumeSizeInBytes value must be equal to or larger
  // than the size of the copied volume, in bytes.
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.
  //
  // See the AWS API reference guide for AWS Storage Gateway's
  // API operation CreateCachediSCSIVolume for usage and error information.
  //
  // Returned Error Codes:
  //   * ErrCodeInvalidGatewayRequestException "InvalidGatewayRequestException"
  //   An exception occurred because an invalid gateway request was issued to the
  //   service. For more information, see the error and message fields.
  //
  //   * ErrCodeInternalServerError "InternalServerError"
  //   An internal server error has occurred during the request. For more information,
  //   see the error and message fields.
