set network point

Fauziah Mahdan — Mon, 11 Sep 2006 20:33:36 GMT

I ahve new itanium server RX2620 installed with 3 internal network point lan0 lan1 and lan2 and 1 more network card.
If Iw ant to make this server connect to more than 1 vlan segment. Can I just assigne lan0 as vlanx lan1 as vlany and lan2 as vlanz. Which of the network point will behave as core network point? What about the network card point?
Pls help

Shalom Fauziah,

Slow down a little.

You can configure any of the LAN cards to be your "core network point"

The HP-UX installation program(Ignite-UX) lets you check a box at install time to designate one of your NIC cards as primary. This means the default gateway(route to the next network) is on that card. That is about as close the the concept of core network point as we get.

Also note that HP-UX does not much like two NIC cards configured on the same network.

e.g.

primary is 192.168.0.11 netmask 255.255.255.0

This make sthe network 192.168.0 and the hostname 11.

To configure another NIC card on the same network(subnet) is a bad idea, though not impossible to do any more.

192.168.1 or 10.1.1 is fine under this scenario.

Network configuration file: /etc/rc.config.d/netconf

Reconfigure networking:
set_parms

Try to avoid using sam for this on a working system as it can sometimes make a working system into a non-working system.

Thanks Steven.
I will follow the instruction to set the network point. Will ask again if I lost. :-)

Thanks

Another stupid question if I have 2db server which is clustering how these 2 servers talk each other? Is it using LAN connection?

When there are two servers clustered, they talk to each other in many different ways, but they at least need to have one LAN interface each, on the same vlan/subnet so that they can talk to each other and check each other's heartbeat. Heartbeat preferably needs to be on a separate LAN if you can do it that way.

When clustering, communication between two servers depends on the clustering software you are using, i.e., serviceguard or veritas clustering. The interface address assignments and like, is handled by your clustering software.

WIth the information you provided, there is not much further that I can predict. If you provide more details and what exactly you are after, I am sure you will get more detailed information.
