Redetect PCI ethernet adaptor using redhat kudzu

Gregory Lee — Thu, 05 Dec 2002 13:04:49 GMT

I added a 2nd NIC card to my Redhat 7.1 netserver & used KUDZU to detect it. It seems that the dectection was successful because in /etc/sysconfig/hwconf, I have 2 entries for the NIC cards:

---------------------------
class: NETWORK
bus: PCI
detached: 0
device: eth
driver: eepro100
desc: "Intel Corporation|82557 [Ethernet Pro 100]"
vendorId: 8086
deviceId: 1229
subVendorId: 103c
subDeviceId: 10cb
pciType: 1
-
class: NETWORK
bus: PCI
detached: 1
device: eth
driver: eepro100
desc: "Intel Corporation|82557 [Ethernet Pro 100]"
vendorId: 8086
deviceId: 1229
subVendorId: 103c
subDeviceId: 10c3
pciType: 1
---------------------------

My first NIC is working & uses the eepro100 module. The 2nd card also uses the same drivers (it's working in another setup).

My problem is now:
- I can't see the 2nd PCI card at /proc/pci or when using "lspci -v".
- Following that I can't configure my eth1 interface, redhat complains that there is no such interface.

How can I force the OS to redetect the 2nd card? Running KUDZU again does nothing since it was already detected. There is still no sign of the 2nd NIC in /proc/pci

Any pointers is appreciated.

Thanks,

Hi,

It may be a hardware pb. Try to unplug the 2nd card and re-plug it again.

Good luck.

hi,

Do you have the following
lines in your /etc/modules.conf ?

alias eth0 eepro100
alias eth1 eepro100

rgds.

Umm, as to the simple part of this, to get kudzu to re-detect the device, just remove the associated details from that 'hwconf' file, then re-run kudzu.

That file is it's 'Database' of devices.

1- Yes, I've checked /etc/modules.conf to ensure I have both entries:
alias eth0 eepro100
alias eth1 eepro100

2- I did try to remove the associated entries in /etc/sysconfig/hwconf. The "new hardware" screen showed up and asked if I wanted to configure it. But when I added the config for my 2nd NIC card, it changed the config for my 1st card (ie. /etc/sysconfig/network-scripts/ifcfg-eth0)!!

Did this a few times & everytime KUDZU said a card was detected with 2 entries in the database but my eth1 was still elusive.

3- Hardware check : I read somewhere that the best way to do it was to unplug it out, startup the server to let KUDZU remove the 2nd NIC from the database - then put the NIC card back in hopefully to a new slot. As this is a production server, this would be my last option.

Hmmm....
