HP Auto Port Aggregation Administrator's Guide for HP-UX 11i v1 and 11i v2 September 2008
• The port has IP addresses or VLANS configured on it. Unconfigure
them from the port and start LAN_MONITOR again.
• The port is not in full-duplex mode. Make sure the port on the
server and on the switch are set to full-duplex or to autonegotiate.
Start LAN_MONITOR again.
• The port is already in a link aggregate or failover group. Find
another port to use.
• The port is not an Ethernet port or is not supported by HP APA.
• The port is down. Wait for the port to come up. Verify that the
port is connected to the switch correctly. If it is, reset the port.
All ports UP?
NO
YES
Verify the active port in the failover group by issuing the following
command:
# lanadmin -x -i linkAggPPA
where linkAggPPA is the failover group instance number.
The Active Port PPA # field lists the active port.
If there are ports in the Port(s) not ready field, verify the port's
operation status by issuing the following command:
# lanadmin -x -p portPPA linkAggPPA
If the Operation Status is up, wait 30 seconds to see if the port becomes
ready or active. If it does not, see the steps for Link partner
configured?. Then, reset the port with the following command and
wait 30 seconds:
# lanadmin -r portPPA
NOTE: Only reset physical ports, not link aggregates that are members
of the failover group.
If the port does not appear in the Port(s) ready list, edit the
configuration files and make any changes. For more information, see
“Editing Configuration Files for Failover Groups” (page 107).
If the Operation Status is down, do the following:
1. If the port is a link aggregate, see the appropriate troubleshooting
section for the specific type of link aggregate to resolve the
problem.
2. Check the cabling from the NIC to the switch. If the cable is
disconnected, reconnect it.
3. Verify that the NIC is operating. See the steps for NIC operating?.
4. Check the nettl log for any other messages.
5. Remove the port from the failover group.
Active port
correct?
NO
YES
Verify that the active port is the one you intended by using the
following command:
# lanadmin -x -i linkAggPPA
where linkAggPPA is the failover group instance number.
If the active port is not the intended one and the intended port is listed
in the Port(s) connected to the active port field, the intended port is
connected to the current active port. For priority-based failover groups,
edit the configuration files and verify the port priority or port cost for
both ports.
