/AUTO_START (Alpha/Integrity servers only)
       /NOAUTO_START

    Sets or clears the instance-specific autostart flag for the
    specified CPUs.

    When autostart is enabled, that CPU will join the OpenVMS active
    set when it is assigned or migrated into the partition. The CPU
    will also autostart if a power-up transition is completed while
    the CPU is owned by the issuing instance.

    Supported only on AlphaServer systems that support partitioning.
