    摘要: Updating firmware on multiple systems or nodes within a merged networked environment includes providing firmware update code and a firmware update utility to a primary node. The firmware update utility determines the presence of a multi-node partition and detects the partition's configuration. The configuration determination includes determining the location of a remote service processor on each secondary node. The primary node creates an image of the firmware update code and distributes the created image to each of the secondary node service processors over a sideband link. Each of the remote service processors would then restart their respective systems. The node's BIOS detects the presence of the firmware update code on the service processor and forces the node to boot the update code directly. After the firmware update is complete, the firmware update code is deleted. When it subsequent restart occurs, the nodes will boot to the merged state.

    摘要翻译: 在合并的网络环境中的多个系统或节点上更新固件包括向主节点提供固件更新代码和固件更新实用程序。 固件更新实用程序确定多节点分区的存在并检测分区的配置。 配置确定包括确定每个辅助节点上的远程服务处理器的位置。 主节点创建固件更新代码的映像,并通过边带链路将创建的映像分发到每个辅助节点服务处理器。 然后,每个远程服务处理器将重新启动它们各自的系统。 节点的BIOS检测服务处理器上是否存在固件更新代码,并强制节点直接引导更新代码。 固件更新完成后,固件更新代码将被删除。 发生后续重启时,节点将引导到合并状态。
