Caution - ILOM enters a special mode to load new firmware. Note the following requirements. 1) The node host power must remain off, so the node ILOM must be accessed from another system on the network to perform the upgrade. 2) No other tasks can be performed in the node's ILOM until the firmware upgrade is complete and the ILOM is reset. To ensure a successful update, do not attempt to modify the node's ILOM configuration, or use other ILOM interfaces (Web, CLI, SNMP, or IPMI) during the update process. Wait until after the update succeeds before making further node ILOM configuration changes. The update takes about 20 minutes.
