ALM-0x2C000027 OS Shutdown Due to Watchdog Timeout (System, Major Alarm)

ALM-0x2C000027 OS Shutdown Due to Watchdog Timeout (System, Major Alarm)


Alarm message:

The OS is forcibly powered off due to the watchdog (arg1) timeout. 

This alarm is generated when the OS is forcibly shut down as the watchdog timed out during the BIOS/power on self-test (POST), OS load, or SMS/OS start process.


This alarm can be generated only after the watchdog is enabled and the timeout action is set to power down.

Alarm object: system

System boot process. For example, BIOS FRB 2, BIOS/POST, OS Load, SMS/OS or OEM.

Impact on the System

The OS shuts down, which interrupts services running on the server.

Possible Causes

  • If the alarm is generated during the BIOS/POST process, the hardware is faulty, or a fault occurs during basic input/output system (BIOS) startup.
  • If the alarm is generated during the OS load process, a fault occurs during OS startup.
  • If the alarm is generated during the SMS/OS process, a fault occurs in the OS.


  1. Disable the watchdog and restart the server.
  2. Use the remote keyboard, video, and mouse (KVM) to check displayed information during system startup. Determine the handling method based on the phases in which the alarm is generated.

    1. If the alarm is generated in the BIOS/POST phase, log in to the iBMC CLI, and run the ipmcget -d port80 command to check information about the port 80.
    2. If the alarm is generated in the OS Load phase, use the remote KVM to view error messages in the OS for fault locating.
    3. If the alarm is generated in the SMS/OS phase, log in to the OS, and check whether faults occur in the software where the watchdog is enabled, or the software is hung.

  3. Getting Help.
