moving lan cards

[Todd McDaniel_1]

I am moving from a 10/100 card to a new Gige card. My network switches can accomodate the change in speed, and I have the driver loaded and the card is claimed.

lan 5 0/0/3/1/0/6/0 igelan CLAIMED INTERFACE HP A9784-60001 PCI/PCI-X 1000Base-T FC/GigE Combo Adapter


I know that I need to edit hpigelanconf.

HP_IGELAN_INTERFACE_NAME[0]=lan5
HP_IGELAN_STATION_ADDRESS[0]=
HP_IGELAN_SPEED[0]=auto_on


My question is what steps do I need to do after I shutdown the application and databases?

How do I shutdown the network and then move the cable and then reenable the network?

Prior to remove the old card, connect to the systems console, disable the card (SAM) and remove the device files (rmsf).

Once the cards are changed, easily use SAM to configure the new card.

I am not physically removing the old card but switching the cabling to the new one.

Other than editing the files I have detailed how do I enable the new lan card and restart the network.

[Todd McDaniel_1]

I really dont trust SAM for something like this...

is there a command line method?

[Torsten.]

Use SAM to unconfigure the old and configure the new card.

I would use the system console to prevent using just this card for network connection.

I agree with Torsten. SAM is the easiest way to do it. It hits all of the correct files.

Simply disable the old card in SAM, and enable the new card with the correct IP. SAM will allow to customize/optimize the to a limited degree.

Manual
Down old interface (ifconfig)
modify netconf and hpigelanconf
move cable
bring up new interface (ifconfig)
Reboot system to make nothing was missed

Why do you think you need to edit the hpigelanconf file? The default should be autoon and such.

If you intend to simply move the IP from the old 10/100 to the new gige card, you could go into netconf file and simply change the interface name in the existing entry for your 10/100 interface and then either reboot or stop/start networking. if you do either of those, it best be from the console.

you could even simply:

ifconfig 0.0.0.0
ifconfig IP etc

and make sure you have the routes you were expecting to have - might need to reestablish the default route

simplest way will be ig GIGE is already available on host..
simply shutdown old 10/10, by putting a 0.0 ip as mentioned.. and then assign the ip to new card.
also update /etc/rc.config.d/netconf .. if you have any card specific file, will need to be updated ..

A good way to change network cards and verify that all of your files are set up correctly is to stop the network, change the network, and restart the network.

This will need to be done on the console.

/sbin/init.d/net stop
ifconfig OLDLAN down
ifconfig OLDLAN plumb
ifconfig OLDLAN unplub

vi /etc/rc.config.d/netconf #Change the interface name to lan5

/sbin/init.d/net start

ifconfig lan5 #Make sure the IP address is correct

netstat -rn #Make sure the default route is associated with LAN5

[Josiah Henline]

For the least amount of interuption, you can put several commands on the same line and experience almost no downtime. You can then go back and change the netconf later.

ifconfig OLDLAN down;\
ifconfig OLDLAN plumb;\
ifconfig OLDLAN unplumb;\
route delete default DEFAULT_ROUTE_IP;\
ifconfig lan5 IPADD netmask NETMASK up;\
route add default DEFAULT_ROUTE_IP 1

Make sure to include the " 1" on the end of the last line. Then you can change the netconf to reflect the new card. I would still recommend running the command from the console in case there is a typo.
