I need to setup a hacmp cluster (my first one, we usually use VCS on AIX), but I require more network bandwith than a normal gigabit etherchannel setup can provide, so I am thinking about using linkaggregation - 2 active adapters to one switch and a single backup adapter to another switch...

Hi,
I'm not from the Solaris world and some of these things are new to me. Can someone tell me if it is possible to configure link aggregation without using LACP?

ifcfg-bonding
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.
