Domain Component List and Logical System
Boards
The domain component list (DCL) identifies the potential resources for a domain. On
midrange or high-end servers, a single XSB can potentially belong to multiple
domains. However, a single XSB can be assigned only to one specific domain. Entry-
level servers are configured with one XSB and one domain, and the XSB is already
configured in the 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. Note that on entry-level
servers, which have only one XSB, the LSB number is 0 by default.
Overview of Steps for Domain Configuration
This section applies to domain configuration after installing a new board in the
midrange or high-end server.
Note – If you create a new domain, you have to install the Solaris OS on the
domain. See the Solaris OS documentation collection for instructions.
Domain configuration typically includes these steps:
