After you upgrade Cisco UCS Manager, a new host firmware policy named "default" is created, and is assigned to all service profiles that did not already include a host firmware policy. The default host firmware policy is blank. It does not contain any firmware entries for any components. This default policy is also configured for an immediate reboot rather than waiting for user acknowledgment before rebooting the servers. https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-manager/GUI-User- Guides/Firmware-Mgmt/3- 1/b_UCSM_GUI_Firmware_Management_Guide_3_1/b_UCSM_GUI_Firmware_Management_G uide_3_1_chapter_0111.html
