adding to or deleting from the total count of CPUs is
performed by any of the following:
• modifying total directly (cpu::total)
• adding or deleting by hw_path (cpu:hw_path)
— if the virtual partition is up, total will be adjusted
automatically (unless the CPUs are already assigned
to the partition)
— if the virtual partition is down, the number of CPUs
assigned by hardware path must be less than or
equal to the pre-existing total
if this is the case, you should first modify total to
allow the additional CPU.
• adding or deleting by CLP
— total will be adjusted automatically
adding to or deleting from the total count of CPUs
assigned to a virtual partition is performed by only
• modifying total directly (cpu::total)
adding by num (-a cpu::num)
• deletion requires decreasing by num (-d cpu::num) or
by hw_path (-d cpu:hw_path)
adding by num (-a cpu::num)
• deletion requires decreasing by num (-d cpu::num)
adding by hw_path (-a cpu:hw_path)
• deletion requires deleting by hw_path (-d
cpu:hw_path)
• this does adjust total if the virtual partition is up
(unless the CPU is already assigned to the partition);
otherwise, if the virtual partition is down, the number
of CPUs assigned by hardware path must be less than
or equal to the current total
• partition can be up or down
adding by hw_path (-a cpu:hw_path)
• deletion requires deleting by hw_path (-d
cpu:hw_path)
• this does not adjust total
• this does not adjust min
• requires the partition to be down
