Managing HP Serviceguard for Linux, Tenth Edition, September 2012

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 11 Before Package Switching
In Figure 12, 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.
NOTE: For design and configuration information about clusters that span subnets, see
the documents listed under “Cross-Subnet Configurations” (page 27).
