Hii all,

Well, I've gone through the pre-reqs for trying to install 11G clusterware on RHEL 5.3.

I'm to the point where i'm trying to run:

./runcluvfy.sh stage -pre crsinst -n node1 -verbose

I get this:

Performing pre-checks for cluster services setup

Checking node reachability...
Node reachability check failed from node "node1 ".
Check failed on nodes:
node1


ERROR:
Unable to reach any of the nodes.
Verification cannot proceed.


Pre-check for cluster services setup was unsuccessful on all the nodes.


I'm just wanting right now, to install a one node RAC system (I will add servers later as I get them online).
I've verified that ssh is working (thinking it may be trying to connect to itself by ssh). I have the keys generated and installed...if I connect ssh as the oracle user back to the same machine, it gets me right on with no prompts for passwords.

nslookup on node1 looks great.

This box has 2 cards....eth0 and eth1. Right now in the /etc/hosts file, I have node1 to the IP for eth0, and node1-priv set for the IP address eth1.

I do have a little trouble understanding what the node1-vip is supposed to do or be set. I found the an IP address one higher than for eth0 wasn't being used, and set node1-vip to be that.

(Can someone explain to me a little more about the vip host?? Is it supposed to somehow point to node1's IP address on eth0 like the regular one does?)

Since this is a one box, one node install...hoping clusterware and checks are just looking at the /etc/hosts file. I've tried playing around, and setting node1-vip to be the same as node1 (IP)...that doesn't work either.

One thing I can guess 'might' be wrong. Does runcluvfy use "ping"? I found the oracle user cannot ping this box from this box. The box (node1) can be pinged from outside the box...it is registered on DNS, I can ssh into it no problem, and again, oracle can ssh into himself on same box with keys properly generated).

I've been looking around, and I just don't see much of what to look at to troubleshoot with this error, I guess everyone gets past the verification the first time with no host unreachable errors?

I'm a bit weak when it comes to networking. Any help greatly appreciated...suggestions, links...etc!!
