Replace Network Interface Card

[Sharon Bi]

Dear all,

I am going to replace old NIC card with a new one on one of my UNIX box.

1) Make a copy of the output of : ioscan -fnC lan
Make a copy of /etc/rc.config.d/netconf file
2) shutdown the box
3) Take out the old NIC card
4) Restart the box

*** By now, will the system hang? If not, then I do a ioscan -fnC lan, will the lan card still be there? then I have to do a " rmsf "?

Thanks a lot for your help!

If you remove the NIC card and restart the system, the OS will do the rmsf for you. No need. If you are going to replace the NIC with an identical one, while the system is shutdown, put the new NIC in after the old one came out. This will keep your HW paths the same. There may be some modifications required in the netconf file but that depends on the card you are putting in. If identical, there should little if any modifications.

do the ioscan -fkC lan and make sure it is coming up claimed. If not, and it says unknown, then you will have to apply the software drivers for it. If it is unknown and a 100BaseT card, what is the driver saying? That will determine the software needed.

If your new card is the same "kind" as the old one, then you have nothing to worry about. If on the other hand this new card is different, you may be required to load (install) the drivers for the new card prior to shutting down the server.

If the card you are going to remove is 100BT Lan card, check the file '/etc/rc.config.d/hpbase100conf'
The parameter HP_BASE100_STATION_ADDRESS[0]
should be blank. This might have your old card mac address, if so make it blank.
Thanks.

Actually, I am going to replace on FDDI card with two Ethernet NICs.

In which case, you will need to modify the /etc/rc.config.d/netconf file, the /etc/rc.config.d/hp*conf file (depending on the driver for the card).

Again, on removing the card the ioscan should not show the HW for that device. On installing the new cards, the ioscan should show the CLAIMED for the new HW address. Make sure you have the appropriate drivers for the type of cards you are going to install.
