1    /ALL

    Stops all eligible secondary processors in the system's active
    set.

2    /ASSIGN

       /ASSIGN=option (Alpha/Integrity servers only)

    Assigns specified processors to the hard partition node after
    they are stopped.

    Option          Description

    $$HARD_         The configuration tree hard partition node. All
    PARTITION       instances running in the hard partition defined
                    by this node have visibility and access to CPUs
                    owned at this level.

    Supported only on AlphaServer systems that support partitioning.

3    /MIGRATE

       /MIGRATE (Alpha/Integrity servers only)

    Transfers ownership of the CPU from the current instance to
    another soft partition.

    Option          Description

    instance_name   The name of any valid running instance in the
                    current hard partition.

    partitionID     The numeric ID of any partition (reflected in
                    the configuration tree) in the current hard
                    partition. An operating system instance is not
                    required to be running with this identifier.

    Supported only on AlphaServer systems that support partitioning.

4    /OVERRIDE_CHECKS

    Directs the STOP/CPU command to bypass a series of OpenVMS
    scheduling checks that determine whether the specified processor
    is eligible for removal from the active set.

    Note that this is not an unconditional operation; other CPU load
    or configuration constraints may prevent the specified processor
    from being stopped.

5    /POWER

       /POWER=OFF (Alpha/Integrity servers only)

    Powers down the CPU after it is removed from the active set. The
    CPU will be powered down while still owned by the instance, prior
    to any assignments.

    The /POWER qualifier cannot be used in conjunction with the
    /MIGRATE qualifier.

    Supported only on AlphaServer GS series systems.
