HP UX Auto Port Aggregation (APA) Software # /sbin/init.d/hplm stop # /sbin/init.d/hpapa stop

System booted without errors?

YES

NIC installed?

YES

NIC claimed?

YES

NO

NO

NO

Edit the /etc/rc.log file and search for the string hpapa. This takes you to the beginning of the HP APA start-up section. If there are failover groups configured on your system, the following message indicates an error:

ERROR: lanapplyconf failed

If there are no failover groups configured on your system, you can ignore the error message.

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 89) 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. For information on how to do this, see the Installing and Administering LAN/9000 Software manual.

2.Verify that the NIC is seated correctly and that it is operational.

3.Reboot the system.
