We usually update firmware, idrac, bios, lifecycle, etc. through Windows. But we are considering to change this practice to using the Update facility in IDrac (under IDrac Settings -> Update and Rollback) instead.
When we update through Windows, there are frequently multiple updates available for each server. We sequence the updates ourselves according to this guide: http://en.community.dell.com/techcenter/extras/m/white_papers/20408841
We do this because we at one time managed to leave a server completely inoperable after updating BIOS, IDrac and LC in the wrong sequence. Dell had to replace some of the hardware to get the server working again.
Question: Using the Update facility in IDrac, we can actually upload multiple updates at the same time. If we do that, will the update facility in IDrac take care of sequencing the updates correctly for us?
Any opinion on the benefits of updating through IDrac or through Windows?
