4 Planning and Documenting an
HA Cluster
Building a Serviceguard cluster begins with a planning phase in which
you gather and record information about all the hardware and software
components of the configuration.
This chapter assists you in the following planning areas:
• General Planning
• Hardware Planning
• Power Supply Planning
• Cluster Lock Planning
• Volume Manager Planning
• Cluster Configuration Planning
• Package Configuration Planning
Appendix D contains a set of blank worksheets which you may find
useful as an offline record of important details of the configuration.
NOTE Planning and installation overlap considerably, so you may not be able to
complete the worksheets before you proceed to the actual configuration.
In that case, fill in the missing elements to document the system as you
proceed with the configuration.
Subsequent chapters describe configuration and maintenance tasks in
detail.
