Qualifiers

/ALL
   Applies the specified operation to all CPUs in the active set.


/ASSIGN
      /ASSIGN [=option] (Alpha/Integrity servers only)

   Assigns the CPU to the current instance if no option is
   specified.

   If an option is specified, the CPU is assigned to that resource.

   Option          Description

   $$PARTITION     The current soft partition of the OpenVMS
                   instance.

   $$HARD_         The hard partition of the OpenVMS instance.
   PARTITION

   Supported only on AlphaServer systems that support partitioning.


/AUTO_START
      /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.


/CAPABILITY
      /CAPABILITY
      /NOCAPABILITY

   Allows bits in the process user capability mask to be set or
   cleared individually, in groups, or all at once.

                                  NOTE

      The SET CPU/[NO]CAPABILITY command will fail if there is
      an active process that requires a capability that is not
      available on any remaining active CPU.

   Specifying the /CAPABILITY qualifier has no direct effect, but
   merely indicates the target of the operations specified by the
   following secondary qualifiers:

   /SET=(n[,..Sets all user capabilities defined by the position
              values n, where n has the range of 1 to 16.
   /CLEAR=(n[,Clears all user capabilities defined by the position
              values n, where n has the range of 1 to 16.

   The secondary qualifiers can all be used at once as long as the
   user capability bits defined in the /SET and /CLEAR parameters do
   not overlap.

   The /NOCAPABILITY qualifier clears all user capability bits.


/CLEAR
      /CLEAR=(n[,...])

   Clears all user capabilities defined by the position values n
   specified by the /CAPABILITY qualifier.


/FAILOVER
      /FAILOVER=option (Alpha/Integrity servers only)
      /NOFAILOVER

   Establishes instance-specific failover relationships for each CPU
   in the instance's potential set.

   When the instance crashes, CPUs with a failover target other than
   the current instance will be assigned or migrated to that target.

   Specifying the /FAILOVER qualifier has no direct effect; however,
   it indicates the target of the operations specified by the
   following options:

   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.

   $$PARTITION     Assigns a resource to the current partition of
                   the current instance.

   $$HARD_         Assigns a resource to the hard partition node
   PARTITION       of the configuration tree. This makes the CPU
                   available to multiple soft partitions below it.

   The /FAILOVER qualifier generates a resource assignment only when
   the current instance crashes.

   Supported only on AlphaServer systems that support partitioning.
   99


/GLOBAL
   Modifies the global cell SCH$GL_DEFAULT_CPU_CAP. This global cell
   is used to initialize the user capability mask of CPUs that are
   brought into the active set for the first time.


/MIGRATE
      /MIGRATE=option (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.


/POWER
      /POWER=option (Alpha/Integrity servers only)

   Turns the power on or off in one or more CPU slots. Valid options
   are ON and OFF.

   Supported only on AlphaServer GS series systems.


/OVERRIDE_CHECKS
      /OVERRIDE_CHECKS (Alpha/Integrity servers only)

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


/REFRESH
      /REFRESH (Alpha/Integrity servers only)

   Examines and updates the OpenVMS context for the specified CPU or
   CPUs, using the hardware configuration tree.


/SET
      /SET=(n[,...])

   Sets all user capabilities defined by the position values n
   specified by the /CAPABILITY qualifier.


/START
      /START (Alpha/Integrity servers only)

   Initiates a request for the specified CPU to join the OpenVMS
   active set if it is not already there.
