Notes to self and to help others along the way...

Upgrading CIMC (including firmware, BIOS, LOM, Ethernet Adapter, LSI)

7/25/2018

Cisco Integrated Management Controller is Cisco proprietary out-of-band management for servers. This is HP's iLO equivalent on Cisco UCS (Unified Computing System) servers.

Note: UCS are servers which are capable of running virtual machines (VMWare ESXi or other hypervisors).

Recently, I did an upgrade on the UCS server's CIMC (which include all the components mentioned in the title). I will go through the steps here. You can also upgrade individual components if needed. My server was running ESXi but that is irrelevant.

Note: Go through the Release Notes of the firmware at Cisco.com and make sure you can go from the source version to the destination version. You have to be logged in to be able to download the software.

​
Here are the steps:

​Gracefully shut down all the VMs running on the UCS server (this isn’t required but recommended) 
Open the CIMC interface by going into the CIMC IP Address (ignore any certificate errors) 

Note: This is not the same as ESXi IP. 

Note: I prefer using Internet Explorer than using Chrome for this upgrade (even though my choice of browser is Chrome).

Click on Launch KVM Console (most times than never, Launch KVM will pop up a Java security error. Even after accepting the security error, Java would fail to launch. 

To fix the Java error, go to your PC’s Start 
button --> Control Panel --> Java --> Security --> Edit Site List --> Add the CIMC IP Address like this: https://10.10.10.1 
Note: I am running Java 8 Build 71

If the hypervisor you are running is ESXi, you will see a similar screen to the one below: ​
Picture
Click on Virtual Media --> ‘Activate Virtual Devices’ 
Click on Virtual Media --> ‘Map CD/DVD Drive’ and browse to where you have downloaded the firmware from cisco.com 
Restart the server so it can boot from Firmware file this time. 
(F12 and F11 if its an ESXi) 
Picture
Press F6 on the boot screen to get in the Boot Menu. (you might have to press F6 multiple times just to make sure you hit it at the right moment) ​
Picture
Select vKVM mapped CD/DVD ​​
Picture
UCS Host Upgrade Utility will start ​​

It can a while to load the firmware files (I guess this depends on network connectivity - mine was pretty good but still it took around 10 minutes).
Picture
When you get the license agreement, click 'I Agree'.
Picture
Now the following screen is where you need to select the components you are planning to upgrade. Select the components (Now click on 'Update' or 'Update All' (I selected All). At that time the upgrade process on each component would start. 
Picture
You would get the option to select Secure Boot Option. I selected 'No' as I wasn't using this feature.
Picture
You can see the progress throughout the process (almost)
Picture
Depending on the source and target version, you might lose connection to this window while some components are being updated. Don't panic. Give it time.

​Note: Some versions where you won't lose access to the KVM Console, you would lose connection when you exit the installer when the firmware is finally applied (Adapter or BIOS firmware).

Server would go through a power cycle and would load up the hypervisor. You can go the CIMC webpage to make sure that version is actually upgraded.
Hope this helps!

I sometimes wish I am also very good with computers. I am not that old. Some people my age are very good with computers. I thought they were ten years younger but I am surprised we were the same age. How come they knew all these stuff? I can't even assemble a desktop. How am I supposed to learn how all these hardware and software work? I wish I also have a computer as a young kid. Maybe that is the reason why I am not computer literate. I thought it was too late for me to learn things then I found out my mother is now better than me.

I am not sure what this is about but if it's another thing about computer I think I am going to start crying anytime now. I couldn't understand anything. We all know it's like a totally different language altogether and for me it is simply out of this world. I don't think there will ever be a time where I will ever understand these things. I know you know what I am talking about. For us seniors, it will never be the same.
