I suspect that you might have not selected the correct/appropriate network settings during the CRS Install (3rd or 4th screen). Also, can you see you can invoke vipca to verify what the current settings look like (as root). Just a thought. Also, what does your crs_stat indicate?

We are doing a RAC install on RedHat Linux.[2.6.9-34.ELsmp #1 SMP ]. Currently on 2 nodes, Clusterware is installed successfully. OCFS2 of clusterware and ASM for database. ASM is working. Database not installed yet. All the components of clusterware working alright. But, in the ASM laert I find: WARNING: No cluster interconnect has been specified. Depending on the communication driver configured Oracle cluster traffic may be directed to the public interface of this machine. Oracle recommends that RAC clustered databases be configured with a private interconnect for enhanced security and performance. oifcfg getif is not working. I don't get any reply. Public is used in place of interconnect. We have collected RDA and working on SR. But you know even after uploading RDA results, analyst is asking what is the Linux version? :( Any suggestion? TIA, Shiva
