Abstract: The disclosure provides an approach for a non-disruptive system upgrade. Embodiments include installing an upgraded version of an operating system (OS) on a computing system while a current version of the OS continues to run. Embodiments include entering a maintenance mode on the computing system, including preventing the addition of new applications and modifying the handling of storage operations on the computing system for the duration of the maintenance mode. Embodiments include, during the maintenance mode, configuring the upgraded version of the OS. Embodiments include, after configuring the upgraded version of the OS, suspending a subset of applications running on the computing system, transferring control over resources of the computing system to the upgraded version of the OS, and resuming the subset of the applications running on the computing system. Embodiments include exiting the maintenance mode on the computing system.

Abstract: A computer system is rebooted upon crash without running platform firmware and without retrieving all of the modules included in a boot image from an external source and reloading them into system memory. The reboot process includes the steps of stopping and resetting all of the processing units, except one of the processing units that detected the crash event, selecting the one processing unit to execute a reboot operation, and executing the reboot operation to reboot the computer system.

Abstract: A computer system is rebooted after updating a boot image without running platform firmware with its power-on self-test of system hardware devices and without retrieving all of the modules included in a boot image from an external source and reloading them into system memory. The reboot process includes the steps of loading one or more updated modules of the boot image into the system memory, executing the boot loader module to load for execution modules of the boot image including a system software kernel and the updated modules, and transferring execution control to the system software kernel.
