Preparing for SEM-HA Installation
This chapter describes the installation requirements and other information you need before installing High Availability for Solstice EM (SEM-HA). It also contains a checklist to use if you have a problem installing the software. The checklist outlines the information you need to provide if you call customer support.
The following topics are covered in this chapter:
- Section 1.1 Overview
- Section 1.2 System Requirements
- Section 1.3 Information you Provide
- Section 1.4 Getting Help
1.1 Overview
SEM-HA enables Solstice EM to be highly available when supported by a cluster of servers (Sun Cluster Servers). A highly available system contains no single point of failure.
Sun Cluster provides high availability support for data service applications, such as Solstice EM. In a HA environment (such as Solstice EM) the software application runs on the primary server. If the primary server fails, a backup server in the cluster takes over designated applications from the primary server, and then applications are able to resume services with minimal disruption.
For more information on Sun Cluster high availability feature, refer to the Sun Cluster 3.0 Concepts Guide.
1.2 System Requirements
Your system must meet the following hardware and software requirements before SEM-HA can be installed.
1.2.1 Hardware Requirements
SEM-HA runs on any hardware supported by the Sun Cluster 3.0 configuration and Solstice EM 4.1.
A cluster configuration will have:
- Two or more servers with local storage
- Shared storage in the form of multihosted disks or RAID arrays
- Cluster interconnect
- Public Network Interface
For setting up the cluster hardware, refer to Sun Cluster 3.0 Hardware Guide
You will also need the following:
- A CD-ROM drive (local or remote).
- No additional space is required beyond the memory requirements for Solstice EM 4.1.
- Superuser password for the machines on which you are installing the High Availability option
Note If the CD-ROM drive is on a different machine, you must have the superuser password for that machine as well.
1.2.2 Software Requirements
The following software must be installed successfully before you can install SEM-HA:
- Solaris 8.0 operating environment
- Sun Cluster 3.0 with Volume Management Software (viz. Solstice DiskSuite (SDS) or Veritas Volume Manager)
1.3 Information you Provide
Read through the Chapter 2, then complete the checklist in TABLE 1-1. You must be able to answer yes or have the appropriate information for each of the questions. If you have problems with your installation, you will need this information when you call customer support.
1.4 Getting Help
If you have problems installing or using SEM-HA, you can call your authorized service provider and have the following information ready:
- Model number of the machine
- Serial number of the machine
- SunOS release number
- Solstice Cluster release number
- Solstice EM release number
