Hi,
Our's is the oracle active passive setup (cold failover cluster). We have two interfaces eth0 and eth1.
Eth0 10.72.40.27/25 -> is meant for public interface. Client communication is happening via eth0.
Eth1 10.72.42.100/24 -> is meant for CRS private interconnect between node1 and node2.
Issue is - SAN server (10.72.42.60) storage is attached as LUN to the node1 using iSCSI via eth0 interface. Due to this, non-production traffic (client traffic) and production storage traffic is sharing the same interface. Due to this, we are seeing lot of I/O issues.
We are looking at enabling additional interfaces to the blade, however, we believe the current IP's in use for the private oracle communication will present a problem for isolating the iSCSI traffic, as they currently reside in the same subnet as the SAN which makes routing difficult.
We need to move the oracle private traffic to new IP's (since it doesn't have to route beyond the subnet gateway) prior to isolating the iSCSI traffic to a specific interface. Any documentation steps to do this?
