Cause
闪存设备未按照 Cisco 问题“CSCuv67115”装载。
此问题最初仅在处于待机状态的管理程序上发生。此问题未通过 ISSU/D、系统切换或重新加载来纠正,而是在处于活动状态的 Supervisor 上观察到。
Logflash 仅用于存储调试命令的输出。系统稳定运行不需要它。
Resolution
解决方法:
关闭并重新打开受影响的 Supervisor 的电源。
在双监控器系统中,这是通过使用 out-of-service module 命令并使用 no poweroff module 命令。确保 Supervisor 处于待机模式,以便恢复不会影响系统的稳定性。
使用 重新启动模块是不够的 reload 或 system switchover 命令。
例:
命令:
-
确认备用管理程序处于 HA 待机状态:
show system redundancy status
-
关闭备用管理程序模块的电源:
out-of-service module <standby sup>
-
接通备用 Supervisor 电源:
no poweroff <standby sup>
-
等待 HA 备用:
show system redundancy status
监控交换机 show logging 输出,以查看 EXT3-fs错误消息是否仍在交换机上记录。如果错误仍在记录,请切换到备用管理程序并重复上述步骤 1-4。
