How to configure NIC failover using HP-APA software on hp-ux?

[petulia3478]

The NIC failover is called LAN Monitor on hpux.

To configure LAN Monitor (NIC failover) on hpux perform the following steps:

1. Cable up the server ports to the switch or switches. For redundancy you would have more than on switch on the same subnet.

2. Check connectivity with the command "linkloop"; normally just linkloop -i then Ethernet address of the switch.

# linkloop -i 

3. Edit the /etc/rc.config.d/hp_apaportconf, add entries for the Primary and Standby ports

HP_APAPORT_INTERFACE_NAME[0]=lan1
HP_APAPORT_CONFIG_MODE[0]=LAN_MONITOR

HP_APAPORT_INTERFACE_NAME[1]=lan2
HP_APAPORT_CONFIG_MODE[1]=LAN_MONITOR
.
.
.

4. Activate the configuration; ignore any cannot open errors.

# /sbin/init.d/hplm stop
# /sbin/init.d/hpapa stop
# /sbin/init.d/hpapa start
# /sbin/init.d/hplm start

5. If you have not assigned the Primary IP address add it to /etc/rc.config.d/netconf. This will configure it after every reboot

6. Query the system for failover groups by running lanqueryconf, the command overwrites the /etc/lanmon/lanconfig.ascii file:

# lanqueryconf -s 

7. The /etc/lanmon/lanconfig.ascii can be changed to adjust the parameters, then run lancheckconf to verify.

# lancheckconf

8. Apply the configuration, make it active.

# lanapplyconf

9. Verify the configuration with lanscan -q and netstat -in

# lanscan -q
# netstat -in
