Abstract

System management software which manages multiples systems generally persists some information about each system it manages. In order to differentiate between managed systems, it may rely on some unique identifier programmed in the hardware. This unique identifier is usually stored in a persistent data device on the system motherboard. This information is programmed as part of the manufacturing process. When the planar is replaced in the field, this information needs to be reprogrammed. Currently this is accomplished as a manual step by the CE (Customer Engineer) replacing the planar. Frequently the CE forgets this step in the process. This article describes two solutions to automating the re-assignment of this unique identifier.
