MORE INFORMATION
The concept of Systems Management Server (SMS) 2.0 site recovery is a fundamental SMS concept, but one that is often not fully understood. Problems resulting from an incorrect site recovery may not be immediately apparent and can be hard to detect from a cursory SMS site examination. As such, it is crucial for you, as the SMS administrator, to become familiar with SMS site recovery procedures and the scenarios in which a recovery is necessary
An SMS 2.0 site recovery occurs whenever an SMS site is installed with a site code or site server name that was previously used in that SMS hierarchy. Repairing and re-synchronizing data are the core tasks of a site recovery, and they are required to prevent interruption of operations and corruption of data.
SMS 2.0 sites that exist in a hierarchy use serial numbers, transaction IDs, and other means of tracking various data that moves up and down the hierarchy. These numbers preserve the ordering of instructions and data. If you rebuild or restore a site, but it is not properly recovered, these numbers are no longer synchronized with other SMS sites in the hierarchy. SMS components at parent and child sites may reject the out of sequence data, which causes a breakdown in normal SMS site communication. To avoid this, you have to follow proper site recovery procedures.
Note: The site recovery procedures that are referenced in the article supersede those in the SMS 2.0 Administrator's Guide, Chapter 18, "Maintaining SMS Systems." These procedures are incomplete and do not fully document the procedures that are necessary to restore an SMS 2.0 site.
