"Host IPMI system event log status" alarm in vCenter Server (1033725)

To resolve this issue, ensure that the NTP settings are correct on the ESXi host, clear the IPMI System Event log file, and reset the sensors.

To clear the IPMI System Event log file and reset the sensors:
Open vCenter Server using the vSphere Client.

In the vCenter Server Inventory, select the ESXi/ESX host.

Click the Hardware Status tab.

Click System Event log under View.

Click Reset Event Log. The red alert is removed from the System Event log.

Click Reset Sensors to reset the host sensors.

Starting with ESXi 5.1 U2, 5,5 P01 and later, you can use the localcli command line to clear the IPMI SEL logs.

To clear the IPMI SEL logs in ESXi 5.1 and later:
Connect to the ESXi host through SSH.

Run this command:

localcli hardware ipmi sel clear

If you find an incorrect date and if you are unable to reset the logs:
In ESX - Restart the management agents and sfcbd-watchdog.

To restart sfcbd-watchdog, run this command from the ESX console:

/etc/init.d/sfcbd-watchdog restart

In ESXi - Restart the management agents.
