IP address conflict
Hi, I am currently working on 2 SPARC-ENTREPRISE T5220 (cluster servers), named SERVER 3A and SERVER 3B.

Both servers have their own Ip ADRESS and share 1 Virtual IP adress to share applications.......

Both servers are available , but can't communicate together right now. For example, from server A, I can't ping server B......, so server A can't use applications of server B.... anymore

I really don't know how to solve this, please help



*******************Network Configuration*******************

Virtual Adress that Both server share : **.***.17.45
IP ADRESS FROM SERVER 3A : **.***.17.41
IP ADRESS FROM SERVER 3B : **.***.17.43
