HP-UX Reference (11i v1 05/09) - 1M System Administration Commands A-M (vol 3)

i
intctl(1M) intctl(1M)
interface cards on the system.
When used with the -C class option, -H
displays information about all interface cards con-
nected to the path and which belong to the specified class.
When used with the
-M option, -H hw_path specifies the hardware path of the interrupt
that needs to be moved to a different CPU.
-I intr_id Used with -M option to specify the interrupt ID of the interrupt to be moved.
-M Migrate an interrupt to a specified CPU. This option must be specified with the
-H, -
I
, -c options.
The -M option should be specified first in the command line followed by the remaining
options which can be specified in any order.
-p Display interrupt information about all the CPUs on the system in a long format with spac-
ing in between the fields.
-r file Restore the system interrupt configuration from the specified file, file. The interrupt
configuration is restored only if all the interface cards and CPUs referenced in the saved
configuration file are still present on the system and the CPUs are in the same state as in
the saved configuration. If new cards and new CPUs are added to the system,
intctl
will continue to restore the interrupt configuration as long as the old configuration has not
changed.
intctl will fail to restore the interrupt configuration if the file permission is
not 0600.
In restoring the system configuration, the command will assign interrupts from the inter-
face cards to the CPUs as specified in the file.
-s file Save the system interrupt configuration to the specified file, file, with file permission 0600.
If the file exists, the content of the file will be overwritten and the file permissions will be
changed to 0600. The command will store the interrupt information of all the CPUs on the
system. This file can be used to restore the interrupt configuration of the system later using
the
-r option.
Interrupt Configuration Display
The interrupt configuration can be displayed sorted by CPU ID (intctl -p) or sorted by interface card
hardware path (
intctl -H hw_path).
By default, the command displays interrupt information about all the interface cards on the system. Here
is a sample interrupt configuration display, and the fields are explained below.

hw path
A numerical string of hardware components separated by slash (/), to represent a bus con-
verter. The first component in the hardware path is the cell (for a cell based system) or the
system bus adapter (for a non-cell based system). The system bus adapter is followed by the
address of the local bus adapter and the interface card. Subsequent numbers are separated
by periods (.). Each number represents the location of a hardware component on the path of
the device.
class The class of the interface card, e.g., lan, tty, ext_bus.
drv name The driver associated with the card.
card cell The cell number of the cell that the card is connected to.
cpu ID An integer value representing the identity of the CPU that the card’s interrupt is assigned
to.
