Managing Serviceguard Eighteenth Edition, September 2010

NOTE: Under agile addressing, the storage units in this example would have names
such as disk1, disk2, disk3, etc. See “About Device File Names (Device Special
Files)” (page 106).
As of A.11.20, Serviceguard supports cluster-wide DSFs, and HP recommends that you
use them. See “About Cluster-wide Device Special Files (cDSFs)” (page 135).
Figure 4-1 Sample Cluster Configuration
Create a similar sketch for your own cluster. You may also find it useful to record the
information as in the sample Hardware Worksheet (page 127), indicating which device
adapters occupy which slots, and the bus address for each adapter; you can update the
details as you do the cluster configuration (described in Chapter 5).
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.
Collect information for the following items; see the Hardware Configuration Worksheet
(page 127) for an example:
