Managing HP Serviceguard for Linux Ninth Edition, April 2009

The switching of relocatable IP addresses is shown in the figures that follow. Users
connect to each node with the IP address of the package they wish to use. Each node
has a stationary IP address associated with it, and each package has an IP address
associated with it.
Figure 3-6 Before Package Switching
In Figure 3-7, node1 has failed and pkg1 has been transferred to node2. pkg1's IP
address was transferred to node2 along with the package. pkg1 continues to be
available and is now running on node2. Also note that node2 now has access both to
pkg1's disk and pkg2's disk.
