Chapter 4132
• Hardware Planning
• Power Supply Planning
• Quorum Server Planning
•LVM Planning
• CVM and VxVM Planning
• Cluster Configuration Planning
• Package Configuration Planning
The description of each planning step in this chapter is demonstrated
with an example worksheet. A complete set of blank worksheets are in
Appendix F, “Blank Planning Worksheets,” on page 443. You can use
them to record the parameters and other data relevant for successful
setup and maintenance. As you go through each step, record all the
important details of the configuration so as to document your production
system. During the actual configuration of the cluster, refer to the
information from these worksheets.
NOTE Planning and installation overlap considerably, so you may not be able to
complete the worksheets before you proceed to the actual configuration.
In cases where the worksheet is incomplete, fill in the missing elements
to document the system as you proceed with the configuration.
Subsequent chapters describe configuration and maintenance tasks in
detail.
