vio server and virtual network adapters

[ogniemi]

a vio server has 4 phisical network adapters.
In vioserver profile I've created 1 virtual network adapter for (trunk and server checkboxes are selected for this ent in profile). The will be only one network/lan running on all these phisical interfaces - all 4 ports on switch are in the same VLAN).

Next, I aggregated ents as follows:

mkvdev -lnagg ent0,ent1,ent2 -attr backup_adapter=ent3

Next, created SEA as follows:

mkvdev -sea ent5 -vadapter ent4 -default ent4 -defaultid 1


mktcpip -hostname vios00 -inetaddr 10.2.47.42 -interface en6 -netmask 255.2
55.255.0 -gateway 10.2.47.1


Is my configuration of virtual interface done properly from technical point of view or it should be done in the other way?

Should virtual devices in vioserver profile be checked as required or no (they will be served for clients - right now I have then not checked as required and everything is fine but somewhere on the net I've seen an example where they were checked as required and don't know why)

THX for any hint how it should be done the best from performance point of view.

would you mind explaining this one to me....what's it doing? I might be able to use this.

mkvdev -lnagg ent0,ent1,ent2 -attr backup_adapter=ent3


Another option might be to etherchannel (ent0 and ent1) as well as (ent2 and ent3) then make sea's out of each of those etherchannelled device. You would be able to split the workload up across the two shared ethernet adapters (alternating two client lpars). Ofcourse if ent0 and ent1 are the same physical card ( two ports ), then this would be a bad idea because you would have a Single Point of Failure.
