系统恢复

The following describes the recovery process for the NetHSM system software. These instructions are only applicable if the API is inoperable, e.g. not responding to API requests. In the case of an operable API perform a factory reset instead. Follow the instructions precisely to prevent any accidental deletion of data.

重要

只有当磁盘上的 GUID 分区表 (GPT) 和分区本身未损坏时，系统恢复才会起作用。启动过程中出现的以下信息可能表明分区已损坏。

Booting 'NetHSM automatic boot (USB or primary system)'

GRUB: No valid configuration found on (usb0).
GRUB: No valid configuration found on (ahci0,gpt1).

GRUB: Booting failed. System will switch off in 10 second.

如果它们已损坏，本说明将导致 NetHSM 系统软件的出厂安装。

系统恢复的步骤如下。

NetHSM 2NetHSM 1

1. 从提供的私人下载页面下载以*...installer.img.zip结尾的安装程序映像* 。

   重要

   下载损坏时安装的同一版本的安装程序镜像。不支持降级或跳版本升级。

2. 解压安装程序映像。

3. 将安装程序映像写入 U 盘。为此，你可以使用图形工具`balenaEtcher<https://etcher.balena.io/>`__。在 Linux 上，也可以使用命令行工具 dd。忽略任何分区表丢失的警告。

4. 将USB闪存盘连接到NetHSM上的USB端口。NetHSM既可以从机身前部的USB端口启动，也可以从机身后部垂直排列的四个USB端口启动。

   备注

   Some USB drives are incompatible with the NetHSM. This results in the NetHSM not recognizing them as a boot media. In case the NetHSM does not boot from the connected USB drive, try a different USB drive model. Best results are achieved with drives that have samller capacities and USB 2.0 interface.

5. Optionally: Connect a keyboard and monitor with the NetHSM.

6. Make sure the system is turned off, but connected to power.

7. Turn the NetHSM on by pressing the power button on the front.

8. Now the software is going to be installed. Wait for ca. one minute until the NetHSM shuts down. Optionally, if you have a monitor connected: When you see the boot menu, select NetHSM automatic boot (USB or primary system) in the first menu and then NetHSM Software Installer in the second menu.

   警告

   请勿从菜单中选择``NetHSM Factory Reset - DELETES ALL DATA!``。这将无法恢复磁盘上的数据。

NetHSM 安装程序将安装系统软件并关闭。
