I  have configuring  clusters from more than 10 years and have worked on Powerha  , RHEL clusters , Pacemaker and many more more or less all clusters behaves or configures in same way as the others .

But the way we can configure PowerHA 7.1 , its so easy and when i say so easy it really is

just ass entries in /etc/cluster/rhosts file <dont ask me what entries >

install cluster binaries

configure /etc/hosts file < how ??? hmmmm>

and run command as below , oh dont forget to create a shared disk for repository .

/usr/es/sbin/cluster/utilities/clmgr add cluster <clustername>  nodes=<host one>,<host2> repository=<disk for repository>
FOR EXAMPLE
/usr/es/sbin/cluster/utilities/clmgr add cluster TESTCLUSTER nodes=TEST301,TEST302  repository=hdisk1

and voila it work and cluster up


We can manage and add resources through command line and i will post them on coming posts.

 LOAD SHARING IN SEA

Below figure provide details of  SEA configuration in a typical  load sharing SEA environment .

The figure shows that eachVIO has been configured with two SEA adapters which are allowing 
different VLAN ids 
 


Trunk adapter in VIO 03 is allowing vlan id 115 and trunk adapter in VIO 04 is allowing vlan id 121 and 116 

I already posted how to configure SEA adapter and  detail explanation in these posts so i am not going in details of creation of SEA adapter in HMC and their respective setting .



You should be configuring atleast two SEA adapters in order to configure load sharing.

http://aix-administration.blogspot.in/2013/01/configuring-sea-adapter-in-dual-vio.html

So create two virtual adapter in vio-03 and vio-04 , with trunk priority one in one vio and trunk priority 2 in other .
Both the trunk adapters  will be configured with different vlan ids  to allow through them .
Repeat the same on the other VIO 

See the figure at VIO 03 trunk adapter allows 115 and the other allows 116 and 121 , on the other hand on VIO 04 , trunk adapter allows 116 and 121 and the other trunk adapter allows 115 .
 
 

So suppose we have two virtual trunk adapters ent6 and ent13 and we are using adapter ent7 for control channel . we can type the command 
ent8 is our physical adapter .
mkvdev -sea ent8 -vadapter ent6,ent13 -default ent6 -defaultid 1 -attr ha_mode=sharing ctl_chan=ent7  

note that we have used two adapters in -vadapter and we have used ha_mode=sharing
of course you have to create vlan tag ids on the new adapter created to allow all the vlan to pass through it .
suppose you get ent14 as your SEA

then you should type for all vlan ids , like the example for 115

mkvdev -vlan ent14 -tagid 115
