Selecting Master Time of Day for Maximum Redundancy

摘要

An approach is provided in which a system selects a first processor as a master Time of Day (TOD) processor in a first TOD topology. The system then assigns a second processor as an alternate master TOD processor to a second TOD topology based upon determining that the second processor is on a different node than the first processor. The system configures to the first TOD topology and, when the system detects a TOD failure requiring a topology switch, the system re-configures to the second TOD topology.

1. A method implemented by an information handling system that includes a memory and a plurality of processors, the method comprising:
selecting a first one of the plurality of processors as a master time of day (TOD) processor in a master TOD topology, wherein the first processor is located on a first node; assigning a second one of the plurality of processors as an alternate master TOD processor to a backup TOD topology based upon determining that the second processor is on a second node that is different than the first node; configuring the information handling system to the master TOD topology; and in response to detecting a TOD failure on the master TOD topology, re-configuring the information handling system to the backup TOD topology.
