HA set for ECC 6.0 in AIX - Unix


Hi Experts,
Our h/w team has setup HA cluster for our ECC 6.0 production system, on which migration will be carried out. Below are our system background:

SAP / DB / OS : ECC 6.0 / Oracle / AIX 7.1

Node A <--> Node B (Active <--> Active)

Node A : DB + ERS(10)
Node B : CI(00) + ASCS(01) + ERS(10)
Node C : DI(02)
Node D : DI(03)

Here in Node A > DB (SPOF) & in Node B > ASCS01(SPOF) are in cluster (AIX - HACMP). Can any one please let me know, is their any need of installing additional DI in Node A with same instance number (00). Also please comment on the setup and areas where care needs to be taken, if any.

Appreciate you valuable response.

Warm regards,
