To create a SEA Failover scenario in a Dual VIO configuration

Follow below procedures step by step as it is written

1. Create two virtual adapters on both the vio say ent1 and ent2 . Keeping in mind that ent0 is physical adapter or real adapter .

2. While creating keep the pvid of both adapters different for example ent1 pvid as "1" and ent2 pvid as "99"

3. Make ent1 as trunk adapter with priority 1 on vio 1 and ent1 as trunk adapter as trunk adapter with priority 2 . To create trunk adapter select the option use this adapter for bridging .

4. Create SEA adapter by issuing command on both vio servers . If your configurationmatches the above just copy and paste the command below on both the vio servers.


mkvdev -sea ent0 -vadapter ent1 -default ent1 -defaultid 1 -attr ha_mode=auto ctl_chan=ent2

5. Add ip address on the new adapter that is ent3 .


mktcpip -hostname $(hostname) -inetaddr <your -ip address> -interface en3 -netmask <your netmask>


6. Make Sure you created SEA adapter and IP address on the adapters .

7. Test the status of adapters by issuing following command .

entstat -all ent3 |grep -i state


It will show status PRIMARY or BACKUP depending on which vio you are running .

8. Change the state of adapter by using command below to check failover .

chdev -dev ent3 -attr ha_mode=standby

9. Test the status of adapters again  by issuing following command .

entstat -all ent3 |grep -i state

It show show failover
