Configure VIOS SEA w. load sharing
Post 302680553 by funksen on Thursday 2nd of August 2012 03:54:21 AM

never tried such a configuration, since we migrate almost everything to blade now, and they just have one vio server each, it's been a long time I configured a sea over two vios
maybe the problem comes with the etherchannel? you wrote you use 2 10gbit interfaces on each vio
do you use an active backup configuration, round robin active active or lacp? I had big problems with 10gbit lacp, so we had to switch to active backup
you could try to remove the etherchannel, and create the sea with one physical adapter, just for troubleshooting
if you don't use etherchannel at all, forget this post..

IFCFG-BONDING(5) Network configuration IFCFG-BONDING(5) NAME
ifcfg-bonding - interface bonding configuration SYNOPSIS
/etc/sysconfig/network/ifcfg-bond* Bonding Interfaces To setup a bonding interface you need a configuration file ifcfg-bond<X> with the usual network settings. But you must add additional vari- ables BONDING_MASTER must be set to 'yes' to identify this interface as a bonding interface BONDING_SLAVE_<X> here you specify the interface name representing the slave network interfaces. BONDING_MODULE_OPTS contains bonding options. Here you can set interface timeouts or working modes ('mode=active-backup' for backup mode). For addi- tional information take a look into the documentation mentioned at the bottom. Note, that this options are not passed as parameters to the bonding kernel module any more, but set via sysfs interface. This variable will be renamed in the feature. BONDING_SKIP_REMOVE_WORKAROUND When set to "yes", a bonding interface will be not removed while ifdown any more to avoid problems, e.g. when some third party ker- nel module, such as Veritas 'llt' module, does not react correctly to the UNREGISTER event and does not remove its references to the bonding interface causing all network related operation to stuck. Note: the bonding options are not reverted when this option is enabled and it is required to either explicitly keep the old options and set them to their default setting on bonding configuration changes or to reboot. Example Example for a bonding interface on eth0 and eth1 using the backup mode ifcfg-bond0 STARTMODE='onboot' BOOTPROTO='static' IPADDR='192.168.0.1/24' BONDING_MASTER='yes' BONDING_SLAVE_0='eth0' BONDING_SLAVE_1='eth1' BONDING_MODULE_OPTS='mode=active-backup miimon=100' Additional Information For additional and more general information take a look into /usr/src/linux/Documentation/networking/bonding.txt. Maybe you need to install the kernel sources to get this additional documentation. The configuration of routes for this kind of interface does not differ from ordinary interfaces. See man routes for details. BUGS
