Bug Description
Brief Description
-----------------
On the Duplex system for Dell PowerEdge R750 machine, standby controller-0 was rebooted due to SM failure , then it was stuck during reboot procedure after the activated controller node sends the reboot command to mtcClient.
The activated controller will send reboot command to mtcClent on the standby controller due to the SM failure(heartbeat missed), and mtcClient tries to reboot the system gracefully. But if the standby controller isn't rebooted within 120s, mtcClient tries to force reboot it using the following command
"echo b > /proc/sysrq-
Severity
--------
Major
Steps to Reproduce
------------------
(1) Stop SM heartbeat on standby controller (controller-0) using the below commands.
sudo bash
date; cat /var/run/
(2) Then mtcAgent on controller-1 sends reboot command to mtcClient on controller-0, and mtcClient tries to reboot controller-0 gracefully. But the controller isn't rebooted within 120s, so mtcClient tries to force reboot it using "echo b > /proc/sysrq-
Or
Execute execute the following command 'sudo -i; echo b > /proc/sysrq-
Expected Behavior
