Methods, systems, and media for timed power-on in a logically partitioned environment

摘要

Methods, systems, and media for timed power-on in a logically partitioned environment are disclosed. Embodiments may disclose determining a time period based upon a time to launch a partition and a time of day associated with the next partition to launch. After determining the time period, a timer is set to boot the system based upon the time period. More specifically, embodiments allow the timed power-on (TPO) and time of day (TOD) of logical partitions to be modified by clients independently of other partitions by determining the system TPO based upon TPOs and TODs of logical partitions as well as the TOD of the system. Some embodiments include initiating a transaction like an interrupt in response to a change in a TPO or TOD of logical partition or the system. Several of such embodiments incorporate adjusting or re-calculating the system TPO in response to the transaction.
