I'm in the middle of trying to install 11Gr2 clusterware on a RHEL box. I've registered with DNS the names for the public, vip and private and scan addresses for each node.
Example, say node one has DNS entries for
And so on for all 5 nodes. I've done this in the past with an older 11G install.
I'm wondering why the installer is borking on this?
Looking up on MOS, the documentation only shows:
P: [INS-40912] Virtual host name: node.domain is assigned to another system on the network.
S: Virtual host name should be unused and down as it's managed by CRS, "ping" can confirm
So, do I need to have networking set something up differently? How do you make the entry non-pingable (i'm guessing this is the problem?)
Thanks in advance,
Don't assign the vip to your system.
When you install Grid it will automatically create the vip for you.
So you can have it in your hosts file but it shouldn't be configured on any of your interfaces.
So when you ping the vip and you get a response it means it is assigned somewhere on your network.
Having the IP in your hosts file or in DNS does not mean you will get a "reply from xyz" message when you ping. You will only get this response if the IP has been assigned.

On your public interface (eg; eth0) , don't set the VIPs. These VIPs just should be in your hosts file.
I told the network folks about the non-pingable requirment...they removed the entries from DNS.
I tried install...said VIPs were still in use...I commented them out of the /etc/hosts file...reran it.
NOW...I'm getting an error of INS-40910 Virtual IP vaausoraiam1-vip. entered is invalid. Details saying it won't resolve to an IP address.
So, what do I tell the network guys to do?
How do you put an entry in DNS for a name/IP combination, and make it non-pingable???
I can't get a straight answer from Oracle support on this either.
Thanks in advance,
You probably want to read my previous post..or you can just ignore it if you want.
Adding an IP into DNS does not make it "pingable". DNS is used for name resolution.
Can you ping the IP address successfully regardless of it's in DNS or not?
If the answer is yes then the IP has already been assigned to a device on your network. What response do you get when you run your ping?
