New Features and Functionality

Sun Cluster Security Hardening

Sun Cluster Security Hardening uses the Solaris Operating Environment hardening techniques recommended by the Sun BluePrints^TM program to achieve basic security hardening for clusters. The Solaris Security Toolkit automates the implementation of Sun Cluster Security Hardening.

The Sun Cluster Security Hardening documentation is available at http://www.sun.com/blueprints/0203/817-1079.pdf. You can also access the article from http://wwws.sun.com/software/security/blueprints. From this URL, scroll down to the Architecture heading to locate the article “Securing the Sun Cluster 3.x Software.” The documentation describes how to secure Sun Cluster 3.1 deployments in a Solaris 8 and Solaris 9 environment. The description includes the use of the Solaris Security Toolkit and other best-practice security techniques recommended by Sun security experts.

Flexible Topologies

Sun Cluster 3.1 software now supports open topologies. You are no longer limited to the storage topologies listed in the Sun Cluster 3.1 Concepts document.

Use the following guidelines to configure your cluster.

• Sun Cluster supports a maximum of eight nodes in a cluster, regardless of the storage configurations that you implement.

• A shared storage device can connect to as many nodes as the storage device supports.

• Shared storage devices do not need to connect to all nodes of the cluster. However, these storage devices must connect to at least two nodes.

Diskless Clusters

Sun Cluster 3.1 now supports greater than three-node cluster configurations without shared storage devices. Two-node clusters are still required to have a shared storage device to maintain quorum. This storage device does not need to perform any other function.

Support for Data Service Project Configuration

Data services may now be configured to launch under a Solaris project name when brought online using the RGM—See “Data Service Project Configuration” section in “Key Concepts – Administration and Application Development” in Sun Cluster 3.1 Concepts Guide for detailed information about planning project configuration for your data service.

Support for the Solaris Implementation of Internet Protocol (IP) Network Multipathing on Public Networks

For more information on the support for the Solaris implementation of IP network multipathing on public networks, see“Planning the Sun Cluster Configuration” in Sun Cluster 3.1 Software Installation Guide and “Administering the Public Network” in Sun Cluster 3.1 System Administration Guide.

Set Secondary Nodes for a Disk Device Group

For more information on how to set a desired number of secondary nodes for a disk device group, see “Administering Disk Device Groups” in Sun Cluster 3.1 System Administration Guide (refer to the procedures for Setting the Desired Number of Secondaries and Changing Disk Device Group Properties). Additional information can also be found in “Cluster Administration and Application Development” in Sun Cluster 3.1 Concepts Guide (See the section on Multi-Ported Disk Failover).

Data Services

For information on data services enhancements, see “What's New in Sun Cluster 3.1 Data Services 5/03” in Sun Cluster 3.1 Data Service 5/03 Release Notes.
