BIOS and Firmware Hotfixes for Management Center Hardware
We provide updates for BIOS and RAID controller firmware on management center hardware. If your management center does not meet the requirements, apply the appropriate hotfix. If your management center model and version are not listed and you think you need to update, contact Cisco TAC.

Hotfixing is the only way to update the BIOS and RAID controller firmware. Upgrading the software does not accomplish this task, nor does reimaging to a later version. If the management center is already up to date, the hotfix has no effect.
Tip |
These hotfixes also update the CIMC firmware; for resolved issues see Release Notes for Cisco UCS Rack Server Software. Note that in general, we do not support changing configurations on the management center using CIMC. However, to enable logging of invalid CIMC usernames, apply the latest hotfix, then follow the instructions in the Viewing Faults and Logs chapter in the Cisco UCS C-Series Servers Integrated Management Controller CLI Configuration Guide, Version 4.0 or later. |
Note |
The management center web interface may display these hotfixes with a version that is different from (usually later than) the current software version. This is expected behavior and the hotfixes are safe to apply. |
Determining BIOS and Firmware Versions
To determine the current versions on the management center, run these commands from the Linux shell/expert mode:
-
BIOS: sudo dmidecode -t bios -q
-
RAID controller firmware (FMC 4500): sudo MegaCLI -AdpAllInfo -aALL | grep "FW Package"
-
RAID controller firmware (all other models): sudo storcli /c0 show | grep "FW Package"
