什么是 system power cycle

  • 系统电源循环是一种从 SP/BMC 重新启动控制器的方法,它将启动节点的非正常关机
  • 执行电源循环后,运行 system console 命令以监视系统启动
  • 确保控制台会话日志记录已开启,以捕获启动过程

何时执行"system power cycle"?

如何执行"系统电源循环"?

  1. 通过以下任一方式访问 SP/BMC:
    1. 从管理主机访问 SP/BMC
    2. 从系统控制台访问 SP/BMC
  2. 运行 system power cycle  命令:

SP node-name>system power cycle
This will cause a dirty shutdown of your appliance. Continue? [y/n]

  • 如果系统电源循环无响应,请尝试:
    • system power off 
    • 等待 90 秒
    • system power on
  1. 运行 'system console' 命令,验证系统如何启动:

SP node-name>system console
Type Ctrl-D to exit.
