If you need to reset your ILOM hardware, you can do so without affecting the host OS. However, resetting an SP disconnects your current ILOM session and renders that component unmanagable during reset.
Log in to the ILOM web interface.
From the Maintenance tab, choose Reset ILOM hardware.
The Reset page appears.
Click the Reset ILOM hardware button, or select the radio button next to the appropriate SP or CMM.
The ILOM hardware reboots. The web interface is unavailable during reboot. You must log in again to continue working in ILOM.
