An Oracle white paper sets out to teach readers how to quickly install and configure Oracle Solaris Cluster software for two nodes that are Oracle VM Server for SPARC (Sun Logical Domains) guest domains. Using the interactive scinstall utility, which is menu driven, users can configure all the nodes of a new cluster easily.

The menus help reduce the chance of mistakes and promote best practices by using default values and prompting for information specific to the cluster. The utility also helps prevent mistakes by identifying invalid entries and eliminates the need to manually set up a quorum device by automating the configuration of a quorum device for the new cluster.

Prerequisites for this procedure:

• Oracle Solaris 10 5/08 or later with required patches
• Logical Domains Manager software version 1.0.3 or later
• Oracle Solaris software group is End User
• Latest patches installed

The minimum configuration for the Oracle VM Server for SPARC:

• Oracle Solaris 10 5/08 OS with minimum patch versions 137042-01, 137111-01, 138042-02, and 138056-01, in both the I/O domain as well as the guest domains
• Oracle Solaris Cluster 3.2 1/09 software with minimum patch version 126106-15
• The cluster hardware is a supported configuration for Oracle Solaris Cluster 3.2 1/09 software
• Cluster software is installed only in the guest domain
• Each server has two spare network interfaces to be used as private interconnects by the cluster software running in guest domains
• SCSI shared storage is connected to the two nodes
• All of the SCSI devices are supported by Oracle Solaris Cluster software as potential quorum devices

Readers are taken step-by-step through the process, with examples and screenshots to simplify the process. The paper offers a sample primary and guest domain configuration. It also shows the initial preparation of public IP addresses and logical hostnames.

The bulk of this 18-page paper is on actually installing and configuring Oracle Solaris Cluster software packages with the scinstall interactive utility in Typical mode. This means Oracle Solaris Cluster software will be installed with the following defaults:

• Private-network address 172.16.0.0. If another cluster configuration (potentially in a different guest domain) is using the same physical adapters for the private network, they must use a different private network address.
• Private-network netmask 255.255.248.0.
• Cluster-transport switches switch1 and switch2.
• Installation security (DES) level Limited.

It should be noted that the example in this guide has no cluster-transport switches. Instead, the private networking is resolved by using cross-over cables.

Readers should also be aware that this document does not cover the configuration of highly available services.
