This manual presents the tasks you need to perform in order to create a functioning OPS cluster using MC/LockManager. These tasks are shown in Figure 1-2 “Tasks in Configuring an MC/LockManager Cluster ”.

Figure 1-2 Tasks in Configuring an MC/LockManager Cluster

The tasks in Figure 1-2 “Tasks in Configuring an MC/LockManager Cluster ” are covered in step-by-step detail in chapters 4 through 7. It is strongly recommended that you gather all the data that is needed for configuration before you start. Refer to Chapter 4, "Planning and Documenting an OPS Cluster," for tips on gathering data.

If you are ready to set up an MC/LockManager cluster, skip ahead to the "Planning" chapter. Specific guidelines on cluster creation are found in the chapters "Building an OPS Cluster Configuration" and "Configuring Packages and their Services."

The following is a quick glance at the remaining chapters of this book:

Chapter 2, "Understanding MC/LockManager Hardware Configurations," describes the hardware configurations used by MC/LockManager and provides a general view of how they work together.
Chapter 3, "Understanding MC/LockManager Software Components," describes the software components of MC/LockManager and shows how they function within the HP-UX operating system.
Chapter 4, "Planning and Documenting an OPS Cluster," steps through the planning process and provides a set of worksheets for organizing information about the cluster.
Chapter 5, "Building an OPS Cluster Configuration," describes the creation of the cluster configuration.
Chapter 6, "Configuring Packages and Their Services," describes the creation of high availability packages and the control scripts associated with them.
Chapter 7, "Cluster and Package Maintenance," presents the basic cluster administration tasks.
Chapter 8, "Troubleshooting Your Cluster," explains cluster testing and troubleshooting strategies.
Appendix A, "MC/LockManager Commands," lists the MC/LockManager commands and reprints summary information from each man page.
Appendix B, "Designing Highly Available Cluster Applications," describes how to create or port applications for HA operation.
Appendix C, "Blank Planning Worksheets," contains a set of empty worksheets for preparing an MC/LockManager configuration.
Appendix D, "MC/Lock Manager Error Messages," lists GMS error messages (OPS 8.0.5 ) and DLM error messages (OPS 7.3.x only) with cause and action text.
