DELL iDRAC goes down during LiveDVD firmware update
Last weekend I had a small task to update BIOS and other firmware on a non-mission critical DELL PowerEdge T310 server. To safe myself a site visit I decided to to do this remotely via iDRAC.
I initially planned to run the updates from DELL Lifecycle Controller, but this was failing with error "The updates you are tying to apply are not Dell-authorized updates" due to out of date version of the Lifecycle Controller itself.
To get around this, I decided to use DELL firmware update LiveDVD, that can be downloaded from here. I mapped the Centos65-OM74-Firmware-LiveDVD.x86_64-1.1.0-Build6.1.iso file to the server via iDRAC and booted from it. Few minutes later, the firmware update utility loaded and gave list of components eligible for an update.
I selected all components that were eligible and started the process. The update was running happily for about 10-15 minutes. Then I left my desk for a few minutes and when I came back the iDRAC client seemed to be frozen. I tried to PING local iDRAC interface IP address from another machine on the same network, but there was no response... At that point the only option left was to drive to the site and check what had happened.
