Overview Serviceguard packages
A package groups application services together. A Serviceguard package
consists of the following:
1. Package name
2. Virtual IP address
3. Application processes that run one cluster node and “belong” to that
package
4. Storage that “belongs” to the application that is started with this
Serviceguard package.
The typical high availability package is a failover package. It usually is
configured to run on several nodes in the cluster, and runs on one at a
time. If a service, node, network, or other package resource fails on the
node where it is running, Serviceguard can automatically transfer
control of the package to another cluster node, allowing services to
remain available with minimal interruption.
The following describes how these components are used to implement a
SGeSAP/LX package. The SGeSAP/LX package name is derived from the
SAP component type and / or functionality.
