Redhat Linux on Blade BL460C

[Linux in BladeServer]

We have HP Blade Server C7000 enclosure and Server is BL 460C ,it has got two switches as well as SAN storage
Installed redhat Enterprise Linux5 x86-64 bit on two of the blades inorder to setup Oracle Clustering
To setup clustering ,its required to have two seperate IP's as different subets as Private and Public. IP series as mentioned below,
Blade1:-
eth0 : 192.168.1.100
eth1: 192.168.2.100
Blade2:
eth0 192.168.1.101
eth1: 192.168.2.101
I am able to ping IP address assigned on eth1 but whenever I tried to access IP of eth0 ,its not getting through,giving messages as "Destination Host Unreachable"

Could you please come up the solution for this,where all I have to check ..Do i have to do something with route....?
Firewall is disabled,
ip_forwarding is enabled.

well ..you have to define the two networks in your switch config and check for google "multihomed linux"
