Rob:
VIOS is by far and away the best way to virtualize Ethernet and provide for
failover/load balancing. That said I don't think Paul has that environment.
Paul:
As someone pointed out VIPA might fit the situation as well. Here's a
document that explains all:
https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_72/rzajw/rzajwpdf.pdf
Start on about page 25. It'll talk about workload balancing and then next
scenario is failover.
I find VIPA to be confusing to most folks, particularly the non IBM i
network administrator that will most likely understand what your trying to
do but then not be helpful in the end since it's not Microsoft/Cisco.

for Load balancing/fail over
We use two VIOS lpars. One controls one ethernet card and the other
controls the other. They both go to different switches.
I'm so damned confident of this solution that I've upgraded VIOS during the
middle of the day. Of course when you use the same solution on three Power
systems and you test it out on the sandbox machine first it helps.

Jim,
https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_73/rzajy/rzajylinka
gg.htm
Thanks for that link.
The diagram was very helpful.
So only one interface and line description are used.
No changes to the interface, only to the line description.
AGGPCY (Aggregate policy) would be set to either *ETHCHL or *LNKAGG (Not
sure which method at this point)
AGGRSCL (Aggregated resource list) would contain the resource names CMN01,
CMN02.
One key question.
The link prerequisites states that this solution is only valid everything
is going to one/same switch.
" All of the ports must be connected to the same link partner (switch)."
My intended solution is going to a 2nd switch.
Is there a different configuration if a 2nd switch is involved?
Paul

Subject: How to configure a 2nd Enthernet port to a 2nd Eternet Switch for
Load balancing/fail over
I'm looking for a resource (pdf/link) on how to configure a 2nd Ethernet
port to a 2nd Ethernet Switch for Load balancing/fail over.
The goal is to provide a higher level of redundancy for if either the 5899
PCI port or the Ethernet switch would fail.
The 2nd port would be connected to a 2nd switch.
I need the details for both the Interface and line description, and any
other TCP/IP config changes (default routes, static routes, etc), if
needed.
Thank You
