HP Auto Port Aggregation Administrator's Guide HP-UX 11i v3 (766140-001, March 2014)

Verify the ports in the failover group by issuing the following command:
# nwmgr -S apa
where xxx is the failover group instance number.
The Membership column shows the ports that compose the failover group.
If the failover group contains ports that you do not want, delete the ports
by issuing the following command:
# nwmgr -d -A links=port-number -c lanxxx
where port-number can be a list of multiple ports numbers separated
by commas and xxx is the instance number of the failover group (for
example, 900).
If any ports you wanted in the failover group are members of another
link aggregate, delete the ports in the other aggregate by issuing the
following command:
# nwmgr -d -A links=port-number -c lanxxx
If there are ports you wanted in the failover group that are not members
of the failover group, verify the type, speed, duplex mode, MTU size,
and checksum offload capability of each port you want with the following
command:
# nwmgr -v -c lanxxx
where xxx is the instance number for the port. All ports must have the
same values. To change an attribute, do the following:
1. Stop the port (unless it is a link aggregate) with the following
command:
# nwmgr -s -A mode=MANUAL -c lanxxx
2. Set the attribute value with the following command:
# nwmgr -s -A attribute=value -c lanxxx
3. Start the port (unless it is a link aggregate) with the following
command:
# nwmgr -s -A mode=LAN_MONITOR -c lanxxx
4. Verify that the port is in LAN_MONITOR mode with the following
command:
# nwmgr -A mode -c lanxxx
If the port is not in LAN_MONITOR mode, possible reasons are:
• 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.
5. Save the current configuration with the following command:
# nwmgr -s -A all --fr cu --sa -S apa
