Dave,
In redhat5, you can/must use udev to control the order of the ethx assignments.
I seem to be unable to post to the list currently. Could you forward it for me?

Thanks for the replies this! So far I've received responses that state:
- Active-active is the best method, although make sure you have stacked switches.
- Active-backup is a better solution for failover/redundancy (nothing new).
- Redhat 4 has bond bugs, one of which is doesn't properly detect the loss of a member of a bond. You'll need to upgrade to Redhat 5.
- Redhat 5 has bond bugs, one of which is the ethx order changes on reboot.
Redhat 4 and 5 have bugs, so either way I'll just have to make sure we address the bugs matching the OS. No one has official recommendations from Oracle, so the choice is back to which is more important - potential performance gains vs. redundancy.
BTW, I was given a couple Metalink references but surprise, surprise, I can't get in currently. :-)
