HP 9000 Containers A.03.01 on HP Integrity Server Administrator Guide HP-UX 11i v3 (5900-3112, June 2013)

10 Integration with SG
HP SG allows you to create high availability clusters of HP 9000 or HP Integrity servers. SG is not
supported inside an HP 9000 container. But, it can be installed in the global container (that is, on
the host system) and configured for applications running inside containers.
HP 9000 system containers support two methods of SG integration:
• Application package model—HP 9000 containers are up on all the failover nodes, but the
monitored application runs inside only one of the containers at any given time. Only the
application is failed over to the other container when required.
• Container (SRP) package model—HP 9000 container is active only on one node at a time.
Failover happens at a container level. The entire container is shut down on the primary node
and started on the failover node. RC scripts must be written to start applications along with
container startup.
HP 9000 classic containers currently supports the application package model only.
To configure SG cluster for HP 9000 containers:
1. Set up the SG cluster.
2. Configure system on each node in the cluster.
3. Select the package model.
4. Select the application that will manage file system and network interface.
5. Configure SG package on the primary node.
After selecting the package model, SG cluster configuration requires the following:
a. Configure shared logical volumes.
b. Configure HP 9000 container on the primary node.
c. Configure HP 9000 container on each failover node.
d. Create or migrate monitor script.
e. Create RC scripts to start applications (container package only).
f. Create or migrate SG package configuration.
6. Copy and apply package configuration.
10.1 Setting up the SG cluster
For information about setting up the SG cluster, see Managing Serviceguard A.11.20 at
www.hp.com/go/hpux-SG-docs.
10.2 Configuring system on each node in the cluster
All the nodes in the cluster must be identical with respect to OE and patch levels. For more
information about how to prepare each node for HP 9000 Containers, see Chapter 2 (page 15).
10.3 Selecting the package model
For SG integration, you can either choose application package model or container (SRP) package
model. HP 9000 classic container supports only the application package model of SG integration.
For HP 9000 system container, select the model based on the requirements. It is easier to transition
the existing SG packages to the application package model and the application failover is quicker
compared to container package model. Container package model simplifies manageability primarily
by supporting shared container file system.
