Table 5. UNIX LLI driver messages for the Ethernet controller (continued)
pnt0-21 add_intr_handler failed! Out of range interrupt number.
Explanation: The interrupt request (IRQ) that was specified, or the IRQ that was found,
conflicts with other devices in the server. Action:
v Modify your hardware settings.
v Run the NETCONFIG program to search for another Ethernet controller.
pnt0-22 add_intr_handler failed! Out of range IPL.
Explanation: The interrupt request (IRQ) that was specified, or the IRQ that was found,
conflicts with other devices in the server. Action: Modify your hardware settings. Run the
NETCONFIG program to search for another Ethernet controller.
pnt0-23 add_intr_handler failed! Vector already occupied.
Explanation: The interrupt request (IRQ) that was specified, or the IRQ that was found,
conflicts with other devices in the server. Action: Modify your hardware settings.
pnt0-24 add_intr_handler failed! Vector already shared at different IPL.
Explanation: The interrupt request (IRQ) that was specified, or the IRQ that was found,
conflicts with other devices in the server. Action:
v
Modify your hardware settings.
v
Run the NETCONFIG program to search for another Ethernet controller.
pnt0-26 The DMA number is not necessary for PCI device.
Explanation: The IBM Netfinity 10/100 Fault Tolerant Adapter does not require a DMA
setting. Action: Edit the SPACE.C file to delete the DMA parameter.
pnt0-29 The IRQ number is already in use.
Explanation: The specified I/O address is already in use. Action: Run the NETCONFIG
program to modify your hardware settings.
pnt0-31 I/O address is not necessary for the PCI device.
Explanation: The I/O address specified is not required. Action: Remove the assigned I/O
address specified for the Ethernet controller
Power checkout
Power problems can be difficult to troubleshoot. For instance, a short circuit can
exist anywhere on any of the power distribution busses. Usually a short circuit will
cause the power subsystem to shut down because of an overcurrent condition.
A general procedure for troubleshooting power problems is as follows:
1.
Power off the system and disconnect the AC cord(s).
2. Check for loose cables in the power subsystem. Also check for short circuits, for
instance if there is a loose screw causing a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and power connectors to all
internal and external devices until system is at minimum configuration
required for power on (see
″
Minimum operating requirements
″
on page 144).
4. Reconnect the AC cord and power on the system. If the system powers up
successfully, replace adapters and devices one at a time until the problem is
isolated. If system does not power up from minimal configuration, replace
FRUs of minimal configuration one at a time until the problem is isolated.
