Managing Serviceguard Eighteenth Edition, September 2010

NOTE: Under agile addressing (see “About Device File Names (Device Special Files)”
(page 106)), the storage units in this example would have names such as disk1, disk2,
disk3, etc.
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).
