我的 ASA 5516 突然停止工作。不再有 In/Outbound 流量，Ping 到内部和外部接口失败。
在设备运行超过 6 个月之前。
在问题发生时，系统日志中仅记录了丢弃消息，例如：

还有一条可疑消息，但这种情况持续了几个月
Jun 29 09:02:38 192.168.100.1 %ASA-3-341011: Storage device with serial number MSA2101XXXX in bay 0 faulty
我能够通过串行接口进入设备，在停机时我检查了默认网关的 ARP 缓存 - 记录是有效的。
在重新加载期间出现此消息：
Jun 29 10:09:50 192.168.100.1 %ASA-3-341008: Storage device not found. Auto-boot of module sfr cancelled. Install drive and reload to try again.
不确定，但存储设备可能会导致这种情况吗？
如果再次发生这种情况，您会建议做什么或尝试什么？
谢谢马特
