and that the CPUs are in the same state as in the saved configuration. The command will continue to
restore the configuration if new cards or CPUs have been added to the system since the interrupt
configuration was saved.
RETURN VALUE
Exit values are:
0 Successful completion.
>0 An error condition occurred.
EXAMPLES
Display information about all interface cards which belong to the class
lan:
intctl -C lan
Display the interrupt information of the card with hardware path
0/4/0/0/5/0 :
intctl -H 0/4/0/0/5/0
Display interrupt information of all the interface cards under the path, 0/4:
intctl -H 0/4
Display interrupt information of all interface cards under the hardware path 0/4 and which belong to class
lan:
intctl -C lan -H 0/4
Display interrupt information about the CPU with CPU ID 3:
intctl -c 3
Migrate the interrupt with ID 1, coming from the card whose hardware path is 0/4/0/0/5/0 to CPU
3.
intctl -M -H 0/4/0/0/5/0 -I 1 -c 3
Migrate interrupts of the card whose hardware path is 0/4/0/1 as specified by the entries in the file
intr_assign .
intctl -M -H 0/4/0/1 -f intr_assign
Store the system interrupt configuration to myconfig.Ifmyconfig already exists, its contents are
overwritten.
intctl -s myconfig
Restore the system interrupt configuration from myconfig .
intctl -r myconfig
Display all the CPUs available in cell_id 2.
intctl -l 2
WARNINGS
The intctl command can be executed only by the super user. The intctl command should be used
only by performance analysts for performance tuning purposes. If care is not taken to redistribute the
interrupts properly, it could lead to a decrease in the overall system performance by overloading some pro-
cessors and by not optimally utilizing the remaining processors.
