ServiceGuard Manager Version A.02.01 Release Notes
What’s in this Version
Chapter 1 9
Note: Because Continental Clusters are always on more than one subnet,
ServiceGuard Manager sees them as two clusters. To see all the
information about a Continental cluster, open two instances of
ServiceGuard Manager. In each instance, connect to a server on the
appropriate subnet.
Figure 1-2 How ServiceGuard Gathers Information
In this diagram, ServiceGuard Manager has been installed on 3 systems,
(Windows, HP-UX, and Linux). Each of these management stations
connects to a server (a node with ServiceGuard A.11.12 or later
installed). The server goes out on its subnets and discovers all the cluster
objects that have ServiceGuard Version A.10.10 or later. (The cluster can
be running on HP-UX or Linux.) It queries for status and configuration
information. If the server has access permissions, the cluster node will
supply the information. (See “Before Installing ServiceGuard Manager,”
below, for a description of configuring node access permissions with
cmclnodelist.)
This information is used to create the map, tree, and properties. In this
example, operators at any of the three stations can connect to the SG
A.11.12 node servers. Because the servers and clusters are all on the
same subnet, all three observation stations can see all three clusters.
