Cisco UCS firmware upgrade

Recently I have upgraded UCS C240 from firmware to 4.0,



1-      Download UCS CIMC firmware from Cisco.com (Path Downloads Home >>Servers - Unified Computing>>UCS C-Series Rack-Mount Standalone Server Software>>UCS C240 M5 Rack Server Software)

2-      Login CIMC and Launch KVM (I was using Java)

3-      Activate the Virtual Devices from Virtual Media tab

4-      Map the ISO to the CD/DVD option.

5-      Then reboot the system waiting for the option to press F6

6-      select the Cisco vKVM-Mapped option (Cisco vKVM-Mapped vDVD1xx)

7-      Now the system will start copying the files and will perform some checks. This step would take 10-15 mins

8-      Host Upgrade Utility will show you list of upgrades, choose all or Specific

9-      When the upgrade completes all components will have status PASS: this would take 20-40 mins

10-   Click Exit and the server will reboot and activate the new CIMC. Wait for the server to come back up and you will see that CIMC has been upgraded
