Dear expert,
I will be installing this for the first time SAP on HA environment (clustered) for only abap stack with 2 app servers.
The scs, ers, db and 2 app servers, these should reside on single server each.
please guide me on how to do this. However, I am going through guides but need quick approach to get the clear picture.
Operating System: Solaris 10.2
Database : Oracle 11.2g
SAP : ECC 6.0 (erp)
Thanks for your efforts!

Hi Rahman,
You may choose the following approach which I had done it many a times
Node 1: DB+ APP1+ERS
Node 2: ASCS+ CI
Node 3: APP2
Node 1 & Node 2 will be configured in HA ( by Unix Team) with failover elements like DB & ASCS.
Node 3 is standalone installation and not part of cluster.
When Node1 fails , Node 2 will have DB+ASCS+CI
When Node2 failes, Node1 will have DB+APP1+ASCS
APP1+CI+APP2 can be configured using SAP logon load balancing to distribute the load.

Hi
To make it simple as of now
You can Install DB on one node and SAPCI on another node with HA on it. To get HA configured out you have to have unix (solaries) team along with you. To even configure ERS b/w these two nodes you need unix team.
Once done then you can intall Apps on two different servers, makes life easy and simple

see below screen shot for HA overview.
There are multiple ways to configure the HA for SAP. The one mentioned above is:
1) All the groups running on node 1 and install a dialog instance on node2. In case of node1 down, then all the groups will move to node2 and the additional dialog instance will be down (no need to down the dialog instance if you lots of resources ie. CPU, memory.)
2) Option 2 :- Run database group on node1 and SAP CI group on node2 and install additional apps on separate server. (I would recommend this)
Make sure you read the installation guide on how to configure / install SAP on HA. Also involve the UNIX/Network team in discussion before you start config/install.
