check mapping status. It should be “Mapped“.
Boot the server and press F6 when prompted to open the Boot Menu screen. In the Boot Menu screen, choose the prepared ISO. Choose Cisco CIMC-Mapped vDVD1.22 and press Enter. Now the server boots from the selected device.
Step 3: Allow the upgrade to take place.
After the HUU boots, Cisco End User License Agreement (EULA) appears, click on I Agree. After you accept the EULA, when the Cisco Host Upgrade Utility window appears with a list of all the components that are available for update. If you want to update all the listed components, click Update all. If you want to update specific components from the list, choose the components that you want to update.
Do you wish to update firmware on all components ? yes
Do you wish to proceed with firmware update? yes
Do you want to enable Cisco IMC secure boot? No
If you update all the components then it may take upto 1 hour.
Click Exit to exit from the HUU. Click Yes at the confirmation prompt.
Reboot the server to apply firmware changes, also check the CIMC firmware version.
Boot the server back into HUU ISO, and click Last Update Verify. This action compares the previously updated firmware version for each component that was updated using the HUU with the current version of the firmware on the components and provides the status of the update.
