Hello,

We have an HP server rx6600 running HP-UX 11i v2 ( setp 2007).
the customer needs to use APA software over lan0 and lan1 network cards.

Can someone inform me how to configure the APA software after the installation.

Thanks and Regards

Roger

Hi,

You need to have APA product installed on your server. It is licensed product.

Read this to configure..

I have attached a small doc which will help you to understand the APA and its configuration .

Configuring LAN Monitor Failover Groups

To configure a LAN Monitor failover group, proceed as follows:

1. Connect the physical devices that are to be in the failover group to the same switch, or different switches/hubs on the
same subnet if switch/hub redundancy is desired.

2. Check that a linkloop between the devices succeeds. If it fails, resolve the physical connection between the devices.

3. If the device to be the primary link does not have the desired IP address, add the IP address for the primary port to /etc/rc.config.d/netconf.
Editing that file or using SAM will preserve the IP address permanently (across reboots).

You can also temporarily assign an IP address to the primary link by typing, for example:

ifconfig lan1 192.5.5.138

4. (HP-UX 11.0 and 11i only) In the /etc/rc.config.d/hp_apaportconf file, create a failover group consisting of primary and standby interfaces,
and assign the configuration mode (LAN_MONITOR).

Example, to put lan1 and lan2 into a failover group:
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

You can also set the LAN_MONITOR mode with: lanadmin -X -p PortPPA AnyLinkAggregatePPA

5. Activate the configuration by typing:
/sbin/init.d/hplm stop
/sbin/init.d/hpapa stop and then
/sbin/init.d/hpapa start
/sbin/init.d/hplm start

6. Query the system for possible link failover groups by typing:
lanqueryconf -s

Running lanqueryconf -s will overwrite the original /etc/lanmon/lanconfig.ascii.

This command will query the system and network for all possible failover groups. The results of the query will be placed in the
configuration file /etc/lanmon/lanconfig.ascii. This file should contain data similar to:

NODE_NAME hpxyz6e
POLLING_INTERVAL 10000000
DEAD_COUNT 3
FAILOVER_GROUP lan900
STATIONARY_IP 192.5.5.138
PRIMARY lan1 5
STANDBY lan2 3

You can manually edit this file and change the number of ports in the failover groups, the dead count, or the poll interval.

7. Verify that the configuration in /etc/lanmon/lanconfig.ascii is still valid by typing:
lancheckconf

8. Create the failover groups specified in the configuration file by typing:
lanapplyconf

This command will create the specified failover groups in the binary configuration file /etc/lanmon/lanconfig.
Check the failover group by using lanscan -q and netstat -in
Note: if you later want to delete all the failover groups specified in the /etc/lanmon/lanconfig.ascii configuration file, type:
landeleteconf

9. The failover group is now operational. A reboot will restart the failover group as long as the /etc/lanmon/lanconfig.ascii file is intact.

Example: Configuring a LAN Monitor Failover Group

Intent: Configure a two port LAN Monitor failover group.
K-class system with lan1 currently configured with IP address
192.1.1.153. We have spare HSC 100BT devices: lan2, lan3, lan4 as
shown by netstat and ioscan

# netstat -in

lan1 1500 192.1.1.0 192.1.1.153 9504123 12437048

lo0 4136 127.0.0.0 127.0.0.1 417 417
# ioscan -fkC lan

lan 4 8/12/2/0 btlan4 CLAIMED INTERFACE HP HSC 100Base-TX
lan 0 10/12/6 lan2 CLAIMED INTERFACE Built-in LAN
#

It is decided that lan2 will be the standby link for the failover group, with lan1 as the primary device.

To configure the failover group:

1. Connect lan1 and lan2 to the same switch, or different switches/hubs on the same subnet.

2. Check that a linkloop between the two devices succeeds. If it fails, resolve the connectivity issue between the devices.

# linkloop -i 1 0x0060B04B7B83

Link connectivity to LAN station: 0x0060B04B7B83
-- OK
#

3. In the /etc/rc.config.d/hp_apaportconf file, verify that an entry exists for the primary and standby interfaces that sets the interfaces'
port configuration mode to LAN_MONITOR.

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

Also set the mode with the lanadmin command:
lanadmin -X -p 1 LAN_MONITOR 100
lanadmin -X -p 2 LAN_MONITOR 100

4. If the device to be the primary link does not have the desired IP address, use the ifconfig command to assign the IP address. Also add
an entry to the /etc/rc.config.d/netconf file to assign the IP address permanently (or use SAM to do it).

# ifconfig lan1 192.1.1.153
#

5. Use the lanqueryconf -s command to query the system for possible failover groups.

# lanqueryconf -s
ASCII output is in file /etc/lanmon/lanconfig.ascii
#

6. Verify that the contents of the /etc/lanmon/lanconfig.ascii have the failover group configured as planned.

# cat /etc/lanmon/lanconfig.ascii
# ********************************************************
# *********** LAN MONITOR CONFIGURATION FILE ********
# *** For complete details about the parameters and how **
# *** to set them, consult the lanqueryconf(1m) manpage **
# *** or your manual.

DEAD_COUNT 3
FAILOVER_GROUP lan100

#

7. Use the lanapplyconf command to build the failover group, and check it with lanscan -q and netstat -in

# lanapplyconf

The failover group is now operational. A reboot will restart the failover group as long as /etc/lanmon/lanconfig.ascii file is intact.

Roro,

You will need to look at the docs provided. One issue is deciding what you want setup. Just a fail group, or a trunk. If you are going to do trunking, you will have to have switched that are supported.
