How MC/ServiceGuard Works
The following examples illustrate scenarios in which MC/ServiceGuard
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
