Abstract

Technologies are provided herein for seamlessly updating firmware in a high availability enabled solution. A system for updating firmware in a high availability enabled solution includes a first active node that is functional on the system and which is connected to a firmware update client and a second passive node that is in an active-passive relationship with the first node. The first node receives a firmware update command and retrieves the updated firmware from the firmware update client. The first node then updates firmware of the second node using the updated firmware. Upon updating the firmware of the second node, the first node sets an indicator flag associated with the second node, which notifies the second node to become the active node upon being rebooted. The first node then reboots the second node, which then updates the firmware of the first node with the updated firmware.
