HP Auto Port Aggregation Administrator's Guide HP-UX 11i v3 (766140-001, March 2014)
Verify the active ports in the failover group by issuing the following
command:
# nwmgr -v -c lanxxx
where xxx is the failover group instance number.
The Active Port(s) field lists the active ports.
If there are ports in the Not Ready Port(s) field, verify the port's operation
status by issuing the following command:
# nwmgr --st -c lanxxx
where xxx is the interface number.
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:
# nwmgr -r -c lanxxx
NOTE: Only reset physical ports, not link aggregates that are members
of the failover group.
If the port does not appear in the Ready Port(s) list, delete the port and
add it with the following commands:
# nwmgr -d -A links=port-number -c lanxxx -S apa
# nwmgr -a -A links=port-number -A mode=LAN_MONITOR -c
lanxxx -S apa
Save the current configuration with the following command:
# nwmgr -s -A all --fr cu --sa -S apa
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.
Verify that the active port is the one you intended by using the following
command:
# nwmgr -v -c lanxxx
where xxx is the failover group instance number.
If the active port is not the intended one and the intended port is listed
in the Connected Port(s) field, the intended port is connected to the
current active port. For priority-based failover groups, verify the port
priority or port cost for both ports with the following command:
# nwmgr -A port_pri -c lanxxx -S apa
where xxx is the port interface number.
For cost-based failover groups, verify the port cost for both ports with
the following command:
# nwmgr -A port_cost, port_pri -c lanxxx -S apa
