After Grid Infrastructure deinstallation: [INS-40912] Virtual host name assigned to another system on the network

If you have ever installed a Oracle Grid Infrastructure Software and deinstalled it and again tried to install it, then you might run in the error [INS-40912] Virtual host name assigned to another system on the network.

If you check to ping node2 from node1 or node1 from node2 through their virtual IP's then that will succeed. This is wrong cause the nodes should NOT be pingable BEFORE the installation of the Grid Infrastructure.

In my case an alias was created for my interface NIC with the use of the virtual IP (which came with the previous installation):

eth0:2 Link encap:Ethernet  HWaddr 00:50:56:B9:0E:AA
       inet addr:  Bcast:  Mask:
       Interrupt:19 Base address:0x2000

So in that case just do:

ifconfig eth0:2 down
