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
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
deleting by hw_path (-d cpu:hw_path)
• can only delete CPU added by hw_path
deleting by hw_path (-d cpu:hw_path)
• can delete any CPU (except the boot processor)
adding by cell
• not available in A.03.xx
adding by cell (-a cell: cell_ID :cpu:: num )
• requires deleting by either of the following:
— by cell (-d cell: cell_ID :cpu:: num )
— by hw_path (-d cpu: hw_path )
boot processor
• not available in A.03.xx
boot processor
• cannot be deleted while the virtual partition is
up
Note that the actual boot processor can change
across virtual partition reboots. Use the
vparstatus -v command to determine which
CPU is the current boot processor
vparstatus output when virtual partition
is down
• shows all bound CPUs assigned to the
partition
vparstatus output when virtual partition is down
• shows CPUs assigned by hardware path
• shows count of CPUs assigned by cell
