Thanks, Frank.

I did some more testing just now and posted the results in another
mail perhaps helps us in certain ways. Please have a look.

Thx & Rgds,

Hi,

I'd the same problem on a DL 580. It seams to be a problem with the intel
chips at the nics. the kernel took the e1000 for both cards, but their must
be a differnce. after two days configuruing and testing, we take one card
out of the system (didn't configure it) at build in a 3COM. Also supported
by HP and running fine.

With regards
Frank

Hi there,

I'm a newbie in Redhat Linux. Recently I sent up a RHEL AS3 server
on ProLiant ML370. It came with two network cards: one is NC7781
(shown in /proc/pci as Broadcom Corp NetXtreme BCM5703 Gigabit
Ethernet) and another shown as PCI device 8086:1026 (Intel Corp)
don't know what model, perhaps it's NC7131 or NC1020. By default
I got the first one recognized by the OS automatically as eth0
and working fine. But when I tried to configure the second, I
can't activate it as if I do so the first card would be deactivated
and lost the connection.

I suspected it as the driver problem, so I downloaded and installed
the e1000 (suppose to be for NC7131) and bcm5700 (suppose to be for
NC1020) driver directly from HP website (of course they are for RHEL
AS3), and followed the instructions exactly. When I used Network
configure wizard to add the eth1, the system captured the e1000 as
the driver automatically no matter how I specify it manually. Once
I activate the eth1, the whole connection thru eth0 got lost
immediately. I have to goto the console manually deactivate eth1
and re-activate eth0 again should it be back to normal.

Can anyone tell me what's going on here and how to get it resolved?

Thx & Rgds,

SCHYU
