Connecting and Installing the Clusters

Language:

Example Cluster Configuration illustrates the cluster configuration the example configuration uses. The secondary cluster in the example configuration contains one node, but other cluster configurations can be used.

Figure 8 Example Cluster Configuration

image:Figure illustrates the cluster configuration used in the example configuration.

Figure 24, Table 24, Required Hardware and Software summarizes the hardware and software that the example configuration requires. The Oracle Solaris OS, Oracle Solaris Cluster software, and volume manager software must be installed on the cluster nodes before Availability Suite software and software updates are installed.

Table 24 Required Hardware and Software

Hardware or Software	Requirement
Node hardware	Availability Suite software is supported on all servers that use Oracle Solaris OS. For information about which hardware to use, see the Oracle Solaris Cluster Hardware Administration Manual.
Disk space	Approximately 15 Mbytes.
Oracle Solaris OS	Oracle Solaris OS releases that are supported by Oracle Solaris Cluster software. All nodes must use the same version of the Oracle Solaris OS. For information about installation, see the Oracle Solaris Cluster 4.3 Software Installation Guide
Oracle Solaris Cluster software	At least Oracle Solaris Cluster 4.1 software. For information about installation, see the Oracle Solaris Cluster 4.3 Software Installation Guide.
Volume manager software	Solaris Volume Manager software. All nodes must use the same version of volume manager software. For information about installation, see Chapter 4, Configuring Solaris Volume Manager Software in Oracle Solaris Cluster 4.3 Software Installation Guide.
Availability Suite software	Different clusters can use different versions of Oracle Solaris OS and Oracle Solaris Cluster software, but you must use the same version of Availability Suite software between clusters. For information about how to install the software, see the installation manuals for your release of Availability Suite software.
Availability Suite software updates	For information about the latest software updates, log into My Oracle Support.

Example of How to Configure Device Groups and Resource Groups

This section describes how device groups and resource groups are configured for an NFS application. For additional information, see Configuring Replication Resource Groups and Configuring Application Resource Groups.

This section contains the following procedures:

The following table lists the names of the groups and resources that are created for the example configuration.

Table 25 Summary of the Groups and Resources in the Example Configuration

Group or Resource	Name	Description
Device group	`devgrp`	The device group
Replication resource group and resources	`devgrp-stor-rg`	The replication resource group
	`lhost-reprg-prim`, `lhost-reprg-sec`	The logical host names for the replication resource group on the primary cluster and the secondary cluster
	`devgrp-stor`	The HAStoragePlus resource for the replication resource group
Application resource group and resources	`nfs-rg`	The application resource group
	`lhost-nfsrg-prim`, `lhost-nfsrg-sec`	The logical host names for the application resource group on the primary cluster and the secondary cluster
	`nfs-dg-rs`	The HAStoragePlus resource for the application
	`nfs-rs`	The NFS resource

With the exception of devgrp-stor-rg, the names of the groups and resources are example names that can be changed as required. The replication resource group must have a name with the format devicegroupname-stor-rg.
