after changing a network cable, how to get network connection back?

[Carol Yu]

Hi, here is what happened and what we did. We have a L class server running HP-UX 11i. 1 NIC card on. But the network connection was pretty bad. It ended up the connector on the network cable to switch port is bad. So I had to use another cable. But after that, we still can't ping the server. Then:
(1) We disabled and enabled the NIC from SAM, didn't work
(2) We deleted the NIC and configure it from SAM, didn't work
(3) We rebooted the server, it worked.

Certainly rebooting the server is a silly idea. I am wondering what is the correct waqy of making the network connection work after you changed the network cable or adjust the NIC settings?

Thanks a lot,
Carol

Carol,

I would suggest downing the interface before you unplug the cable, replacing the cable, then enabling the interface again.

ifconfig lanx down

Change the cable.

ifconfig lanx up

Or maybe the switch disabled the port?

Hi,

to be sure everything has been taken care of after a cable replacement,

these are the steps.

/sbin/init.d/net stop
/sbin/init.d/nettl stop
/sbin/init.d/net.init stop

Now restart these services in the reverse order.
/sbin/init.d/net.init start
/sbin/init.d/nettl start
/sbin/init.d/net start

Hope this helps.

I had a similar problem before out switch was on UPS power. Everytime the power was gone I used lanadmin to reset the NIC.
This brought it back to respond.
