98 SPARC Enterprise Mx000 Servers Administration Guide • August 2009
An LSB on a midrange or high-end server has up to four processors (when a Uni-XSB
is assigned to the LSB); therefore, the LSB needs 32 processor IDs. An LSB on an
entry-level server, which supports only a single processor, requires only eight
processor IDs.
TABLE A-1 shows the relationship between LSB numbers and starting processor (proc)
numbers, in hexadecimal/decimal format. The Solaris prtdiag(IM) command
provides the LSB numbers and CPU chip numbers in decimal format for components
that are part of the domain.
