Multiple NICs and remote install of RHEL causes issues ...


Hi,

We are using an IBM xSeries 440 server. This host has 3 NICs (one built-in on motherboard -- the broadcomm one and the other 2 were NIC cards in PCI slots in terms of Intel Pro*100).

The server originally had RHEL AS 3 U6 (32 bits) and we wanted to install RHEL AS 4 U3 remotely. The intent was to install it remotely without any manual intervention.

So we did copy the vmlinuz file and initrd image for RHEL AS 4 U3 (32 bits) as stated here:
http://www.redhat.com/magazine/024oc...cm_edmsept_007

The installation ISOs and kick-start file were shared via NFS.
This is what we provided in the menu.lst file of GRUB:

title Remote Install
root (hd0,0)
kernel /vmlinuz_remote ks=nfs:nfs_server_ip:/path/to/ks.cfg vnc vncpasswd=mypassword
initrd /initrd_remote.img

After making this entry as the default entry and saving grub, we rebooted the box anticipating that it will start the install.

The problem was, when we rebooted the box so as to start install via kickstart, it seems it was not able to find the kickstart file which was NFS mounted...Further investigation revealed that, the installer was perhaps NOT treating the onboard Broadcomm NIC as eth0 but one of the NICs in the PCI slot (one of the Intel Pro*100) was treated as eth0. AS none of the Intel Pro*100 had ethernet cables connected, the installer was not able to find the ks.cfg via NFS.


Obviously, we could remove the two Inte Pro*100 NICs from the PCI slots and go ahead with the install.. But the idea was to be able to remotely install without any manual intervention at all...

Hence we were wondering what could be done to achieve that ?
How do we make sure that the installer treats the onboard ethernet (the broadcomm one) as the eth0 and not the ones in the PCI Slots (the Intel Pro*100).

Will appreciate any pointers/suggestions.

Thanks,
The LnxKido.

I met the same symptom few week before. In CentOS4.4 Linux box, there're two onboard Intel82573 network devices, and later add one Intel Dual-Port ethernet work card in PCI-X slot. That's saying, the box has total four network interface. When I try to install Linux via NFS, these four cards mess, the Dual-Port have eth0 and eth1, and onboard are assigned to eth2 and eth3. During current the network installation, it seems we have to connect the cable to corresponding port. So, LnxKido, I'll look for the better resolution with you.

Regards,
Phillip
