Spending a little planning time up front to become familiar with the server slot and bus configuration can prevent you from having to take unnecessary time later trying to troubleshoot configuration mismatches. In many cases, it completely prevents mismatches from occurring. Note: PCI bus number assignment changes only if PCI bridge devices are added or removed from the system. Compaq recommends adding controllers to slots in the order in which the slots appear on the bus. Following this recommendation prevents the occurrence of the scenarios discussed in the "PCI Test Configurations with ProLiant Servers" section of this paper. Such occurrences are most likely when controllers are added to an existing server configuration out of order, leaving vacancies between slots that reside on the same bus. 13UK-1200A-WWEN
