configuration file for Cluster

[Sharon Bi]

Dear All,

We have a three nodes cluster. Currently they are on a FDDI ring. Due to network upgrade, we are going to remove FDDI. So I have to plan to remove FDDI card, put in TWO new 100BT NIC.

As for hardware, I have already decided to go for a HP-PB NIC. But I don't know how to do it from software side. Could anybody teach me how to do that?

I have posted this question before. Why we choose to use HP-PB NIC is because there is an I60 in the cluster which does not have HSC slot. And please see the below plan:

Halt the system
- Turn off the power Switch
- Remove the FDDI card
- Reboot the system and do not turn on Cluster
- Remove the FDDI device file /dev/lan1:
Rmsf ?H 8
- Check the HP-PB LAN 9000 driver in the Kernel, look for the driver:
Lan1: HP-PB LAN 9000 Link S800
- Halt the system
- Turn off the power switch
- Plug the new HP-PB 100Base-T/9000 card
- Reboot
- The server autoconfigure and create the necessary device files
- Check the autoconfiguration of LANIC
Ioscan ?fn lan

Check the LANIC hardware path and S/W state field for value of CLAIMED (indicating the network driver is installed) for /dev/lan1
- Check if the network connectivity:
Ifconfig lan1
- Enable Cluster

I don't know what change shall I make in cluster configuration files? If the FDDI card was lan1 on the system before, can I make it remain lan1 after I change it to Ethernet card?

Thank you very much for your help!

Check what patch HP-PB requires.
If not change IP's and lanx is the same (lan1) should be okay. The have the same dev/lan, I am not sure if you could use lanadmin. You can set it up through a procedure, delete te old device rmsf, recreate insf -e. If not working use mksf. See man for each of them.
Otherwise, you should be ok.

I would be tempted to save you config files in /etc/cmcluster some where and rerun the cmquerycl again and let it discover your ans. And then reedit your config files and apply it again.
