 * <p>Updates the gateway virtual machine (VM) software. The request immediately triggers the
 *          software update.</p>
 *          <note>
 *             <p>When you make this request, you get a <code>200 OK</code> success response
 *             immediately. However, it might take some time for the update to complete. You can call
 *                <a>DescribeGatewayInformation</a> to verify the gateway is in the
 *                <code>STATE_RUNNING</code> state.</p>
 *          </note>
 *          <important>
 *             <p>A software update forces a system restart of your gateway. You can minimize the
 *             chance of any disruption to your applications by increasing your iSCSI Initiators'
 *             timeouts. For more information about increasing iSCSI Initiator timeouts for Windows and
 *             Linux, see <a href="https://docs.aws.amazon.com/storagegateway/latest/userguide/ConfiguringiSCSIClientInitiatorWindowsClient.html#CustomizeWindowsiSCSISettings">Customizing your Windows iSCSI settings</a> and <a href="https://docs.aws.amazon.com/storagegateway/latest/userguide/ConfiguringiSCSIClientInitiatorRedHatClient.html#CustomizeLinuxiSCSISettings">Customizing your Linux iSCSI settings</a>, respectively.</p>
 *          </important>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { StorageGatewayClient, UpdateGatewaySoftwareNowCommand } from "@aws-sdk/client-storage-gateway"; // ES Modules import
 * // const { StorageGatewayClient, UpdateGatewaySoftwareNowCommand } = require("@aws-sdk/client-storage-gateway"); // CommonJS import
 * // import type { StorageGatewayClientConfig } from "@aws-sdk/client-storage-gateway";
 * const config = {}; // type is StorageGatewayClientConfig
 * const client = new StorageGatewayClient(config);
 * const input = { // UpdateGatewaySoftwareNowInput
 *   GatewayARN: "STRING_VALUE", // required
 * };
 * const command = new UpdateGatewaySoftwareNowCommand(input);
 * const response = await client.send(command);
 * // { // UpdateGatewaySoftwareNowOutput
 * //   GatewayARN: "STRING_VALUE",
 * // };
 *
 * ```
 *
 * @param UpdateGatewaySoftwareNowCommandInput - {@link UpdateGatewaySoftwareNowCommandInput}
 * @returns {@link UpdateGatewaySoftwareNowCommandOutput}
 * @see {@link UpdateGatewaySoftwareNowCommandInput} for command's `input` shape.
 * @see {@link UpdateGatewaySoftwareNowCommandOutput} for command's `response` shape.
 * @see {@link StorageGatewayClientResolvedConfig | config} for StorageGatewayClient's `config` shape.
 *
 * @throws {@link InternalServerError} (server fault)
 *  <p>An internal server error has occurred during the request. For more information, see the
 *          error and message fields.</p>
 *
 * @throws {@link InvalidGatewayRequestException} (client fault)
 *  <p>An exception occurred because an invalid gateway request was issued to the service. For
