The configuration and administration of the IRIS FailSafe™ system software and its IRIS FailSafe NFS™ and IRIS FailSafe Webserver options are described in this guide, the IRIS FailSafe Administrator's Guide. The configuration of other IRIS FailSafe options, such as IRIS FailSafe Sybase®, IRIS FailSafe INFORMIX®, and IRIS FailSafe Oracle® is described in separate guides. They are listed in the section “Related Documentation,” below.
This guide was prepared in conjunction with Release 1.2 of the IRIS FailSafe product.
The IRIS FailSafe Administrator's Guide is written for the person who administers the IRIS FailSafe system. The IRIS FailSafe administrator must be familiar with the operation of CHALLENGE® or Origin™ servers, as well as optional CHALLENGE Vault or CHALLENGE RAID storage systems, whichever is used in the IRIS FailSafe configuration. Good knowledge of XLV and XFS is also required.
IRIS FailSafe configuration and administration information is presented in the following chapters and appendices:
Chapter 1, “Overview of the IRIS FailSafe System,” introduces the components of the IRIS FailSafe system and explains its hardware and software architecture. This chapter also describes IRIS FailSafe node states and how failover works. It gives overviews of the procedures for configuring a new IRIS FailSafe system and for upgrading an IRIS FailSafe system from release 1.1 to release 1.2.
Chapter 2, “Planning IRIS FailSafe Configuration,” describes how to plan the configuration of an IRIS FailSafe cluster.
Chapter 3, “Configuring Nodes for IRIS FailSafe,” describes several procedures that must be performed on nodes in an IRIS FailSafe cluster to prepare them for IRIS FailSafe.
Chapter 4, “Creating the IRIS FailSafe Configuration File,” explains how to edit configuration file templates to create or modify an IRIS FailSafe configuration file.
Chapter 5, “Testing IRIS FailSafe Configuration,” describes how to test the configured IRIS FailSafe system.
Chapter 6, “Administering IRIS FailSafe,” explains how to perform basic IRIS FailSafe system administration tasks, such as starting and shutting down the IRIS FailSafe system, getting current status information, and using administrative commands to change node state.
Chapter 7, “Upgrading an IRIS FailSafe Cluster,” explains the procedures for upgrading the hardware and software on IRIS FailSafe nodes, including installing new IRIX releases, IRIS FailSafe software, and patches, adding new high-availability services, and installing a new version of the configuration file, /var/ha/ha.conf.
Chapter 8, “Performing Simple Hardware Maintenance,” explains how to perform simple cable replacement procedures and how to replace batteries in the remote power control unit that is included in IRIS FailSafe clusters with CHALLENGE S systems.
Appendix A, “Messages About Configuration File Errors,” lists error messages that can appear as output of the ha_cfgverify command and gives an explanation of each one.
Appendix B, “System Troubleshooting,” explains how to troubleshoot IRIS FailSafe system problems.
Appendix C, “Sample ha.conf Configuration File,” describes an example IRIS FailSafe cluster configuration and provides the IRIS FailSafe configuration file for this configuration.
