I tried to upgrade the firmware of S2360 from 4.0.1a to 4.0.4h or 4.0.4k using UCSM, CIMC and HUU but each time the CMC update fails. All the other components were updated successfully. The 4.0.4k appears as the backup fw for the CMC although it was activated by the HUU. Any ideas to workaround this?
