Online firmware update

When you use an online method to update firmware, you can perform the update without shutting down the server operating system. Online firmware updates can be performed in-band or out-of-band.

In-band

Firmware is sent to iLO from the server host operating system.

The iLO drivers are required for in-band firmware updates.

During a host-based firmware update, if iLO is set to the Production security state, it does not verify user credentials or privileges. The host-based utilities require a root (Linux and VMware) or Administrator (Windows) login.

When iLO is configured to use the High Security, FIPS, or CNSA security states, user credentials are required.

Out-of-band

Firmware is sent to iLO over a network connection. Users with the Configure iLO Settings privilege can update firmware by using an out-of-band method.

If the system maintenance switch is set to disable iLO security on a system that uses the Production security state, any user can update firmware with an out-of-band method. If the system is configured to use a higher security state, user credentials are required.
