HP Auto Port Aggregation Administrator's Guide HP-UX 11i v3 (766140-001, March 2014)
If you see error messages about link aggregate attributes, do the
following:
1. Stop HP APA with the following commands:
# /sbin/init.d/hplm stop
# /sbin/init.d/hpapa stop
2. Correct the attribute in the appropriate configuration file.
3. Restart HP APA with the following commands:
# /sbin/init.d/hpapa start
# /sbin/init.d/hplm start
Search for the string hplm in the /etc/rc.log file. If there are failover
groups configured on your system, the preceding message indicates an
error. If there are no failover groups configured on your system, you
can ignore the error message.
Also look for any driver and network errors.
Do the following:
1. Verify that the network card is seated correctly and that it is
operational.
2. Check that your network physical port connectors between the NIC
and the switch (or wall plug) are fully connected.
Verify that the NIC has been claimed by the operating system. Issue the
following command:
# ioscan -fkC lan
If the driver has been claimed, the driver name appears in the Driver
column and CLAIMED appears in the S/W State column for the lan
class and hardware path. See “Scanning the system hardware”
(page 69) for more information on ioscan.
If the software state is UNCLAIMED, do the following:
1. If the class is unknown and driver is UNKNOWN, the interface driver
has not been generated into the kernel. Verify that the /stand/
vmunix file contains the appropriate keyword for the NIC you are
using with the following command:
# what /stand/vmunix | grep -i driver-name
For example, if you are using the 1000Base-T NIC, the igelan
keyword appears. If it does not, you must edit the file and create
a new kernel.
2. Verify that the NIC is seated correctly and that it is operational.
3. Reboot the system.
Verify that the NIC is operating. Enter the following command:
# nwmgr -v [-c lanx | -S driver-name]
If the Interface State is DOWN, do the following:
1. Check the status of the Link LED.
If the LED is off, check the connection to the switch. Make sure that
the switch is configured in the correct mode and is autonegotiating,
if necessary. Reset the NIC with following command:
# nwmgr -r -c lanxx
2. Make sure the link speed and duplex mode match the settings on
the switch. If they do not, set the correct link speed and duplex
