upgrading the idrac fw from the idrac gui wont cause a system reboot, and rebooting the idrac also does not reboot the system, only the idrac itself is affected. That said, what I would suggest is to SSH into the idrac, then run racadm ping . if it can ping the NTP server, I would suggest a reboot of the idrac, using the racadm racreset command. The server itself will not reboot.   #Iwork4Dell 
Hello, I have several PowerEdge R430 servers.  Each one of them has iDRAC 8 Enterprise.  Some of the iDRAC's clocks are wrong.  I have set their time zone to the correct one and then set NTP servers several hours ago. But the iDRAC's clock in one of them is still wrong.  In the help, it's written that iDRAC will sync with NTP if the setting is configured.  Is there a bug in the iDRAC?  Is there any way to force a NTP sync?  The host O/S is Vmware ESXi. Thanks in advance.
