I suggest using the Dell Update Package, which you can run from a supported OS.  There is a windows version and a Linux version that you can download from support.dell.com: Windows:  [URL] Linux:  [URL] If neither of those work, you might need to run the repair package.
I decided last week to start getting up to speed with some much needed firmware updates on my PER710 ESXi 4.1 hosts.  After exploring the options, I decided to try using Unified Server Configurator (USC) to perform these updates.  I used USC as instructed to perform updates one R710 and the procedure went flawlessly.  I was very impressed and moved onto the next hosts... I tried two more hosts, and they didn't go too well.  I initiate the platform update and I believe I got as far as the following screen: [IMAGE] Then after maybe a minute or so, USC crashes and displays the following: [IMAGE] I contacted Dell Pro Support on both of these servers, and they replaced the motherboards.  They said the USC image must have been corrupted when the server shipped.  Has anyone seen this behavior before?  Dell suggested a method of updating the broken USC image using the BUU cd; I was just hoping to get more information before I play Russian Roulette on the next server I try to update.
