An LSB has four processors as a maximum (when a Uni-XSB is assigned to the LSB); therefore, an LSB needs 16 processor IDs. Note that 32 IDs are assigned for future expansion.

TABLE A-1shows the relationship between LSB numbers and starting processor (proc) numbers, in hexidecimal/decimal format. The Solaris prtdiag command provides the LSB numbers and CPU chip numbers in decimal format for components that are part of the domain.
