Managing Serviceguard Fifteenth Edition, reprinted May 2008

Planning and Documenting an HA Cluster
Hardware Planning
Chapter 4 135
Create a similar sketch for your own cluster, and record the information
on the Hardware Worksheet (see “Hardware Configuration Worksheet”
on page 141). Indicate which device adapters occupy which slots, and
determine the bus address for each adapter. Update the details as you do
the cluster configuration (described in Chapter 5). Use one form for each
SPU. The form has three parts:
• SPU Information
• Network Information
• Disk I/O Information
SPU Information
SPU information includes the basic characteristics of the systems you
are using in the cluster. Different models of computers can be mixed in
the same cluster. This configuration model also applies to HP Integrity
servers. HP-UX workstations are not supported for Serviceguard.
On one worksheet per node (see “Hardware Configuration Worksheet” on
page 141), include the following items:
Server Number
Enter the series number; for example, rp8400 or
rx8620-32.
Host Name
Enter the name to be used on the system as the host
name.
Memory Capacity
Enter the memory in MB.
Number of I/O slots
Indicate the number of slots.
