ProcedureSPARC: 如何强制实施崩溃转储和系统重新引导

使用以下过程可以强制实施系统崩溃转储。该示例遵循以下过程，说明如何使用 halt -d 命令强制实施系统崩溃转储。运行此命令后，您需要以手动方式重新引导系统。

  1. 为系统键入 Stop 组合键。

    特定的 Stop 组合键取决于您的键盘类型。例如，您可以按 Stop-A 或 L1-A。终止时，请按 Break 键。

    PROM 将显示 ok 提示符。

  2. 同步文件系统并写入故障转储。 


    > n
ok sync

    将崩溃转储写入磁盘后，系统将继续重新引导。

  3. 确认系统引导至运行级别 3。

    引导过程成功完成后，将显示登录提示。
