Subject: How to identify unused NICs
Reply to author | Forward | Print | Individual message | Show original | Report this message | Find messages by this author
Hello,
Help a Solaris Admin out ...I'm a newby to  HP-UX 11 and  I inherited
a HP-UX 11  server.

I visually see an open unused NIC.  There are multiple NIC in use
which I do not want to disturb as this is a production server.

What native tools do I have to confirm which is the *free* interface
to use and configure on this server?
The free NIC port I saw was one of a 2 x port NIC which one was
already in use.

I posted some details below, this server is part of a 2 node
ServiceGuard Cluster. So some NIC's - I guess - are used for the
heartbeat which I want to avoid.

Looking at the output below it might be lan2 as the unused interface
but how can I be sure?

I'm not a ServiceGuard expert but does the NICS involved with the
heartbeat show in the netstat output as well?

...

On each node:-

lanscan will give a list of NICs

ifconfig lanx      will show if it is configured

Also the network config that is set up at boot time, along with routes
is contained in  /etc/rc.config.d/netconf.

Regards,

Ted.

From your output of netstat -rn, lan0 lan1 and lan3 are used.
use netstat -in to see other configured lan (standby used from cluster).
use lanadmin -x Y where Y is you ppa number to see if you have a cable
connect to other lan.
example
lanadmin -x 0
Speed = 1000 Full-Duplex.
Autonegotiation = On.

Regards
Antonio
