Planning a PCI System Configuration
Modifying a multi-controller configuration and understanding what happens to specific physical
devices can be confusing in a PCI-based network server. 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.
