Updating iDRAC does not need a host reboot. Only iDRAC FW get rebooted after FW update.
 Hello Dell community.  Apologies if it's an easy request. I've only dealt with Cisco and Supermicro in the past.I have to upgrade our racks from 4.40 to 5.0.10.20 and would like to know how disruptive it is. They're ESX hosts. Do I need to put it into maintenance or it's fairly safe not. The reason for the upgrade is that we're running an old version and we are getting regular "CPU 1 temperature is greater than the upper critical threshold." alerts. These only last for 5 secs. My understanding is that this is a low risk change and doesn't require a reboot of the host to upgrade iDrac. Can you confirm ? Thanksregards Gaetan
