standby lans

Carme Torca — Wed, 22 Dec 2004 06:25:55 GMT

Hi!,

How could I see the standby lans?, How could I know what lan is the standby of other lan?
Is there any file to see this?.

I have a lot of lans in one server and I don't known how to look this.

I know that lan1 and lan6 are the standby but I don't known of which lan.

Thanks very much!
Carmen.

Hello,

Go to sam
Networks and communications->interface cards
And you can see list of lan interface and their state: "enable or disable"

Hello

I take it the server is in a service guard environment ?

cmviewcl -v will show you which lans are configured in your cluster and what is primary, standby and heartbeat.

cmquerycl -c -l net

will give you a more detailed status

Then of course, to view non service guard nic config, look at /etc/rc.config.d/netconf

If on the other hand you are not using serviceguard but you WANT to configure failover LAN, you need a product called APA (Auto Port Aggregation). This allows the configuration of 2 NICs in load-balanced or failover mode.

haven't got any reference to this lans...
Does it means that there is not standby configured whith this lans??

Thanks very much!

Hello Carmen,

It seems you haven't configured it as standby lan's When they are configured you will not see them in the lanscan output and of course they must appear in the

/etc/rc.config.d/hp_apaportconf

file.
