Update Firmware for Management Consoles Without Servers Downtime

You can update firmware for management consoles for CMC, iDRAC and Lifecycle Controller without downtime on the servers:
  1. In a scenario, where both the primary and the standby CMC is present, you can update the CMC firmware without servers or IOMs downtime.
  2. To update firmware on the primary CMC, see the Updating Firmware section. When you update firmware on the primary CMC, the standby CMC takes on the role of the primary CMC. Hence, IOMs and servers downtime does not occur.
    • NOTE: The firmware update process impacts only the management consoles of IOM and iDRAC servers. There is no impact on the external connectivity between the servers and IOMs.
  3. To update iDRAC or Lifecycle Controller firmware without a downtime of chassis, perform the update using the Lifecycle Controller service. For information on updating server component firmware using Lifecycle Controller, see the Upgrading Server Component Firmware section.
    • NOTE: While updating any other components such as Mezzanine cards, NDC controllers, and BIOS, a downtime of the servers occurs.
