Status so far. I decided to bypass the E0 network port and put another nic out of a pc I had in slot 5. I then tested in single mode and multi mode and everything worked great. I'll try out cluster failover tommorrow. Since I have each nic going to a different network card on my cisco 6509, I decided to hit the netapp from machines on each of the network cards on the cisco and instantly saw traffic on both interfaces. It only maxed at a 100mb thoughput and was distributed between the interfaces on the Netapp. I was hoping to be able to get double the performance. Is this a limitation of the bus or the virtual Interface?

thanks

Hi,

I think what Sam Cramer said about switch might be considered :

A multi-mode vif will, when attached to a switch or set of interfaces on another host capable of trunking, balance network load across its constituent links. Most switches distribute the load across the links by hashing an incoming packet's source and destination address. Thus, if incoming packets share the same source and destination address, they will flow over the same link. This may be what is biting you here.

Try to get an expert from the Cisco support to help you in knowing how to configure your Cisco 6509 switch, and the way you could make some tries to see if it works.

Also , I wonder if you do not bad in using identical names for your devices (vif01 in both Filer). Also (again), try to use ifconfig only to set up the IP adress. Instead of : > ifconfig e6 mediatype 100tx-fd > ifconfig e0 mediatype 100tx-fd > vif create multi vif01 e6 e0 > ifconfig vif01 `hostname`-e6 mediatype 100tx-fd partner vif01 you could try : > ifconfig e6 mediatype 100tx-fd > ifconfig e0 mediatype 100tx-fd > vif create multi vif01 e6 e0 > ifconfig vif01 `hostname`-e6 partner vif02

At the end (not also), I noted in you sysconfig -v output that one of two interface was down. So to be sure you right use single or multi here is : - failover purpose : ifconfig e1... ifconfig e2... vif create single vifa e1 e2 vif favor e1 ifconfig vifa... - loadbalancing purpose : ifconfig e1... ifconfig e2... vif create multi vifa e1 e2 # no favor expected ifconfig vifa...

Thank you to let us know how it works.
