Create SEA Failover in VIOS

We need 2 virtual adapters, one for sea and another for ctl_chan
after created two adapters, from the scratch we will have ent2,ent3 as our virtual adapter
now we start with create sea adapter

$ mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid 1 -attr ha_mode=auto ctl_chan=ent3

**defaultid is the vlan number of your vios (depends on you)

Now we will have ent4 which will be our sea adapter.
Check it with

$lsdev -dev ent4 -attr

Now we need an ip address for sea adapter.
Start with this

$cfgassist

Then choose for our sea adapter which is ent4 for now.

Please do the same with VIOS_2, so you can have sea failover operates correctly.
