Bonding with RHES5 on DL585 G7

Hi!

Bondig with RHES5 on DL585 G7 does not work smoothly.

After every reboot the network ist not available. Only if we issu service network restart or ifdown/up bond0, network connectivity is established.

Here's our config:

modprobe.conf

alias eth0 bnx2
alias eth1 bnx2
alias eth2 netxen_nic
alias eth3 netxen_nic
alias eth4 netxen_nic
alias eth5 netxen_nic
alias bond0 bonding

ifcfg-bond0

DEVICE=bond0
BOOTPROTO=none
USERCTL=no
ONBOOT=yes
IPADDR=xxx.xxx.xxx.x
NETMASK=255.255.255.0
BROADCAST=xxx.xxx.xxx.255
BONDING_OPTS="mode=1 miimon=100"

ifcfg-eth0 and ifcfg-eth2

DEVICE=eth0
BOOTPROTO=none
HWADDR=1C:C1:DE:07:98:EC
ONBOOT=yes
MASTER=bond0
SLAVE=yes

Thank you all for your help.

Wolfgang

Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008)

Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: eth2
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: eth0
MII Status: up
Link Failure Count: 0
Permanent HW addr: 1c:c1:de:07:98:ec

Slave Interface: eth2
MII Status: up
Link Failure Count: 0
Permanent HW addr: 78:e7:d1:58:56:fc

But this is after a network restart is done.

Wolfy,

On my biond configuration - I have bonding options in /etc/modprobe.conf instead of ifcfg-bind0 sir:

alias bond0 bonding
options bond0 mode=active-backup miimon=100 primary=eth0

Also.. did you do mkinitrd rebuild of your initrd sir?

Regarding to the instructions from RH for RHEL5, bonding options should be configured in ifcfg-bondX.

And why should we use mkinitrd? we use the kernel supplied driver from RH.

Any other suggestions?

Thanks

Wolfgang

The mkinitrd suggestion was one of our fixes one other box that was exhibiting the same issue as yours. Listen or Not -- it is a free world.

Is there anything in your startup logs if you are able to capture them sir? Maybe thre is a clue in /var/adm/messages sir?

Also:
What else do you have in /etc/sysconfig/networking-scripts? do an "ls -lt" maybe there is one or 2 misconfigured file in there.

You can also check:

root@arrog01# chkconfig --list network

and see if it is ON at RLs where it should start (2,3...)

And Lastly:
Suggest to fall back to non Bond config if the network subsystem starts on boot.
