Cisco Host Upgrade Utility
The Cisco Host Upgrade Utility is a tool that upgrades the following firmware:
Cisco Integrated Management Controller (CIMC)
LAN on motherboard (LOM)
LSI (for any third-party LSI storage controllers that are installed)
Cisco UCS P81E Virtual Interface Card (VIC)
The image file for the firmware is embedded in the ISO. The utility displays a menu that allows you to choose which firmware components to upgrade. After the upgrade, you can also choose whether to reboot with existing CIMC settings or with the factory default CIMC settings.
If you are using UCSM Mode to integrate this server with Cisco UCS Manager, you must use Release 1.2(x) CIMC and BIOS firmware. To upgrade the 1.2(x) firmware, you need to use the Cisco Host Upgrade Utility for 1.2(x).
