Managing Serviceguard 13th Edition, February 2007

Planning and Documenting an HA Cluster
Hardware Planning
Chapter 4 139
Create a similar sketch for your own cluster, and record the information
on the Hardware Worksheet. 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, 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.
Network Information
Serviceguard monitors LAN interfaces.
NOTE Serviceguard does not support heartbeat communication across routers
between nodes in the same cluster.
