C9800 stuck in boot

[Bill lo]

Hi all

設備:C9800-L-F  在一次重啟後就不能正常開機:

Chassis 1 reloading, reason - Critical process crash
Mar 2 11:53:17.358: %PMAN-5-EXITACTIvp: Process manager is exiting:
Mar 2 11:54:30.396: %PMAN-5-EXITACTION: F0/0: pvp: Process manager is exiting:
Mar 2 11:54:48.078: %PMAN-0-PROCESS_NOTIFICATION: R0/0: pvp: The process lifecycle notification component failed because Processes Shutdown Timeout

甚至也無法進入ROMMON

請問有人遇到相同狀況嗎?

看log是因为process crash导致的重启，还有process shutdown timeout的异常，尝试重新加电呢？

如果不行还是直接找TAC吧，crash的问题普通用户不太好排查解决

Hi ilay

感謝你的回覆，由於該產品沒有服務合同，所以無法開立Case支持。

由於該設備沒有服務合同，所以無法請求TAC支援；

thx

该问题的确比较负责，看到有类似的案例，也都是建议如下 ：

1、 - Push reset button for more then 10 seconds (have a factory reset), upgrade to last advisory release first : https://software.cisco.com/download/home/286323158/type/282046477/release, then restore the configuration from backup.

2、

Do not use 17.3.1.  Use a more recent version, like 17.3.5b.  

Force the WLC to boot into ROMMON and then use "emergency-install" to put a newer firmware into the WLC.

3、If you have TAC support, pls reach out to them & see how you can recover.

Hi  Rps-Cheers

感謝你的回覆，

1/有試過，但設備還是不斷加載。

2/無法中斷開機程序進入ROMMON mode

3/目前暫時無法開立Case

thx
