In TABLE 4-4, the XSB board number xx is in the range of 00-15; the IOU board number

xxis the IOU board number corresponding to the XSB board number. For example, XSB 00-0 has IOU#00-PCI#0.

Domain Component List and Logical System Boards

The domain component list (DCL) identifies the potential resources for a domain. A single XSB can potentially belong to multiple domains. However, a single XSB can be assigned only to one specific domain.

XSB numbers are not used in domain configuration, however. The software requires that each XSB number “map” to a logical system board (LSB) number. Processor numbers and I/O bridges are based on LSB numbers. Appendix A contains additional information on LSB and device path names.

Overview of Steps for Domain Configuration

This section applies to domain configuration after installing a new board in the system.
