Today I was installing a grid infraestructure whe one of the checks performed by the OUI (Oracle Universal Installer) I get the following error;
[INS-40912] Virtual host name: node.domain is assigned to another system on the network.
I’ve asked the network team two virtual IP, you need it to install a cluster with grid infrastructure. The problem is that the sysadmin has included the twice IPS in the network cards (NIC) (this is done with bounding in linux / unix and NIC teaming in Microsoft Windows) with which they respond to ping, I think is what OUI are doing as a check. In this case nothing should respond to ping in order to pass the requirements of OUI. The solution has been to remove the IPs from the NICs, it works fine.
