SolutionYou can put a STOP/CPU 1 command somewhere in your
startup procedures to disable the second CPU.
I don't think you can boot from other than the primary
CPU (CPU 0) and if the primary CPU dies, your system
dies. I am not aware of any SYSGEN parameters that
control this.

Re: Limiting an SMP AlphaServer to one CPU
START /CPU 1
to restore the full capabilities. If you remove SMP license the system will attach an OpenVMS addl-user 100 units and enable the second CPU. You'll also get a message to operator's log.

Re: Limiting an SMP AlphaServer to one CPU
the SMP_CPUS system parameter (a bit-mask) can be used to prevent ANY secondary CPUs from booting. Setting SMP_CPUS to 0 will nevertheless allow the primary CPU to boot.
See $ MC SYSGEN HELP SYS_P SMP_CPUS
