is used to switch control of a package between different cluster servers:
Example 1: MC/ServiceGuard Package
Switchover
The SG cluster shown in Figure B-1 represents a typical scenario:
❏ Node 1 runs the application packages A and B
❏ Node 2 is runs the application package C
❏ Node 3 is runs the application packages D, E, and F
❏ The nodes are connected by two redundant LANs connected by way of
a bridge
❏ Each node has its own root disk and shares volume groups
