[Linux-cluster] virtual ip

[Celso K. Webber]

Hello,

As far as I can tell, this way of adding VIPs was introduced in RH Cluster Suite 4.0 and onwards, Cluster Suite under RHEL versions 2.1 and 3.x used to implement VIPs using Linux alias interfaces (eth0:0, eth0:1, etc.).

Celso.

A subinterface (eth#:1) would show up in ifconfig, but RHCS adds the VIP directly to the eth# interface itself as a second address, so you have to use 'ip addr' to view all the IP's. Ifconfig will only show you the first.

The same on node two. Where does the virtual ip get set at, and what command can you type to find out the virtual ip?
