I've got a number of Dell R710 machines with the standard quad bnx2 internal
network card. Now I have a few of these that I am using as cluster login nodes
and they have eth0 pointing to the internal cluster network and eth1 pointing
to our corporate LAN. A couple of these boxes simply refuse to run eth1 at
gigabit speed. They all come up at 100Mb full duplex.
I've gone through the standard troubleshooting procedures (I think):
Update to latest BIOS on R710 (1.3.6)
Update to latest Broadcomm firmware from Dell (NETW_FRMW_LX_R246418.BIN)
Update to latest bnx2 driver from Dell (v1.9.20d)
Swapped out ethernet cables
Double check settings on switch (it is a 1U 48 port Cisco although I have the
same problem connecting to a Netgear).
Done googling around and added
"options bnx2 disable_msi=1" to /etc/modprobe.conf
The box is running RHEL 5.4 and I see this problem with both stock -164 kernel
and the older -128.7.1.el5_lustre.1.8.1.1 kernel that I really need to be
using. ethtool always reports eth1 as running at 100Mb/s except when the
network is first coming up and it has "unknown" values for both Speed and
Duplex.
Has anybody else encountered something like this?
# ethtool eth1
Settings for eth1:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Link detected: yes
If I try and force eth1 to be 1000Mb/s, I get the following error:
# ethtool -s eth1 speed 1000 autoneg off duplex full
Cannot set new settings: Invalid argument
not setting speed
not setting duplex
not setting autoneg
Any help or hints would be greatly appreciated!
Thanks
Tim
