Managing Serviceguard A.11.20, March 2013

Figure 14 Before Package Switching
Figure 15 shows the condition where Node 1 has failed and Package 1 has been transferred to
Node 2 on the same subnet. Package 1’s IP address was transferred to Node 2 along with the
package. Package 1 continues to be available and is now running on Node 2. Also note that
Node 2 can now access both Package1’s disk and Package2’s disk.
NOTE: For design and configuration information about clusters which span subnets, including
site-aware disaster-tolerant clusters, see the documents listed under “Cross-Subnet Configurations”
(page 29).
