某局点 S5560X-EI重启后堆叠分裂无法恢复

现场4台S5560X-EI堆叠，环境异常掉电，重新上电后slot2无法加入堆叠组。

1、重新上电后检查配置，发现slot2d的irf-port相关的配置丢失。

2、查看诊断信息，发现slot2的配置文件时间异常,slot1的时间是4/16，slot3和slot4时间是4/13

3、进一步查看日志信息发现，4/16保存操作时没过多久就ssh登出了

%@4343915%Apr 16 20:59:11:514 2026 NN-USR-AL-F15-SW-IRF SHELL/6/SHELL_CMD_INPUT: Input string for the save command is the Enter key.

%@4343916%Apr 16 20:59:11:609 2026 NN-USR-AL-F15-SW-IRF SHELL/6/SHELL_CMD_CONFIRM: Confirm option of command save is yes.

4、分析是触发该已知问题：关于H3C部分产品保存配置时退出登录导致配置丢失的技术公告 - 知了社区

堆叠环境保存配置是一台一台执行的，涉及该问题的版本建议保存配置时预留2分钟时间，如果堆叠成员数量越多，需要预留的时间越长。
