US 2004/0210705 A1 · Methods, systems, and media for timed power-on in a logically partitioned environment

Abstract

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.

Dependent claims

A method for launching at least one logical partition of a system, the method comprising:

determining a time period based upon a time to launch a partition of the at least one logical partition and a time of day associated with the partition, the partition being the next partition to launch of the at least one logical partition;
scheduling a launch for the system based upon the time period;
and
launching the system in response to the scheduled launch for the system.
