I just received my Dell PowerEdge C6100 and found it’s software quite a bit outdated. After searching around quite a bit I found the resources lacking for explaining how to perform these updates. So in this post I’m going to quickly cover updating the BMC firmware on each blade.
The system I received had four different versions of the BMC software installed, additionally Two were branded as MegaRAC and the others branded as Dell. This update didn’t fix the branding (and I’d love to remove the Dell branding as it’s kind of annoying) it did, however, fix a number of other issues that I was experiencing such as:
- Console Redirection failing to connect
- BMC losing it’s network connection after a couple of minutes
- Slow responses, with occasional failures to load pages
- Remote IPMI tools being unable to read sensors status
The first step is too download the latest version of of the BMC software from Dell’s support site (Or a direct link, I’ve also taken the liberty of hosting a copy myself). I recommend you go through the process of entering the service tag of each of the blades and make sure that Dell recognizes them as existing even if they’re out of support.
There has been mention of versions of these blades that had custom modifications for DCS and any attempts to modify the BIOS or BMC will likely cause you to end up bricking the remote management board or the motherboard.
Even with the regular board there is always a risk of bricking it, though firmware updates have gotten a lot more reliable and I haven’t experienced a mis-flashed motherboard in years. You’ve been warned.
The BMC was fairly straight-foward. I installed the 64-bit version of Fedora 19
on a thumbdrive, downloaded version 1.30 of the BMC software (get the file
PEC6100BMC130.exe). The file itself is a self-extracting zip archive
which can be extracted using the regular unzip utility.
Inside you’ll find two folders, KCSFlash and SOCFlash should both be put on the
live drive within the KCSFlash. You’ll need to set the execute bit on the
contents of the linux directory and the linux.sh file. You’ll also need to
glibc.i686 package. Afterwards it’s as simple as booting each
chassis off the drive and as root run the linux.sh script.
If the KCSFlash fails, the SOCFlash will more likely than not work but it is
slightly more dangerous. If you need it mark the
linux/socflash_x64 as executable in the SOCFlash folder
and run the flash8.sh script.
After that you’re going to want to reboot into the BIOS and ensure the IPMI ethernet port is set to dedicated, as this switched it back to “Shared” on me.
