Aruba 5412R zl2 is restarting - Reason for system reboot: Watchdog reset

Hi,

 

I have an Aruba 5412R zl2 switch. For the last two days, the switch reboots about every 8 hours. It has two management modules, but the issue exists with either of them connected or with both of them connected. After each reboot the log shows something like this:

 

I 09/02/17 11:15:30 00062 system: AM1: System went down without saving crash information
I 09/02/17 11:15:30 03006 system: AM1: Reason for system reboot: Watchdog reset
 
Is there any possibility to disable the watchdog to avoid the restart?
 
Thank you,
Florin

A watchdog is something that checks the functioning of your system, and restart the system when components stop responding (properly). This is done in the hope that after a restart, things will be better.

 

Restarts due to watchdog timeout indicate a serious issue with your hardware/software. And periodic watchdog issues should be investigated by Techsupport.

I did that, but they are moving slowly. Until then, I am trying to disable this watchdog. So, is there any possibility to do this?

I'm not sure on that; TAC should be able to help you with that question for a workaround.

 

If you believe TAC should be moving quicker, feel free to use the escalation procedure described here, as having a network interruption every 8 hours seems unacceptable to me.
