The SET CPU command syntax is:
SE[T] C[PU] [/qualifier] [<XMI-node>]
where <XMI-node> is the XMI node number of the processor to be affected.
If you omit <XMI-node>, the system uses the current processor.
If you omit all qualifiers, the SET CPU command immediately causes the
specified processor to become the primary processor. The console terminal is
then connected to the new primary processor, and the next console prompt
is generated by the designated processor.
If you use qualifiers, the SET CPU command changes the processor
parameters that take effect at the next system reset. These qualifiers
modify the EEPROM (if the lower key switch is set to Update) and take
effect immediately:
• /ENABLE
• /NOENABLED
• /VECTOR_ENABLED
• /NOVECTOR_ENABLED
The /NEXT_PRIMARY qualifier acts the same as if you had issued a
SET CPU/NOPRIMARY command for all other nodes. To undo /NEXT_
PRIMARY, you can issue the SET CPU/PRIMARY/ALL command. The
/PRIMARY qualifier means that the specified processor is eligible to be
the primary processor.
The /NOVECTOR_ENABLED qualifier removes the vector processor
from the system configuration. The scalar processor is not affected.
The /VECTOR_ENABLED qualifier restores the vector processor to the
configuration.
The effect of the SET CPU command qualifiers is shown on the BPD lines
of the system self-test display (see Section 6.5).
NOTE: For performance reasons, the scalar processor of a scalar/vector pair
should not be made the primary processor when other scalar processors are
in the system.
