Abstract

Method For Interlocked Deferred Partition Reset In A Logical Partitioning Environment Disclosed is a method to interlock asynchronuos resets/reboots to a logical partition signaled from the partition's operating system or the hardware management console (HMC). In a logical partitioning computer architecture, IO/CPU/memory resources housed within one large computer system can be partitioned to form sub-computers which exhibit the same behavior and characteristics of a typical machine. These logical partitions are required to exhibit the same operational characteristics of a computer, including the ability to turn them off or reboot them without affecting any of the other logical partitions supported by the larger system framework. Specifically, the reset/reboot signals can originate from the logical partition's operating system or from a HMC external to the host machine.
