CentOS

Follow attachment. I have a vip from heartbeat service, it is 10.137.157.12.

I want to create one more vip on this heartbeat service, it is 10.188.63.249.

How i do this?

Heartbeat hasn't had any maintenance since about 2009. The current CentOS versions have switched to using corosync and pacemaker instead of heartbeat. Also, you have about 2 weeks left before CentOS 5 dies and goes out of support.
