If the APA State is
Down
, do the following:
1.
Check that all ports in the failover group are connected to the
switch.
2.
Verify that the link partner is configured for no trunking. Make
any changes, if necessary, and wait 10 seconds. Then, verify that
the failover group is up.
Correct ports in
failover group?
NO
YES
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.
