RAID Card Firmware Compatibility
The firmware on the RAID controller must be verified for compatibility with the current Cisco IMC (3.1.5)
and BIOS (2.3) versions that are installed on the server. If not compatible, upgrade or downgrade the RAID
controller firmware accordingly using the Host Upgrade Utility (HUU) for your firmware release to bring it
to a compatible level.
See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to bring
server components to compatible levels:
