Planning a Subsystem
28 HSG80 ACS Solution Software V8.8 for IBM AIX Installation and Configuration Guide
Defining Subsystems
This section describes the terms this controller and other controller. It also
presents graphics of the Model 2200 and BA370 enclosures.
Note: The HSG80 controller uses the BA370 or Model 2200 enclosure.
Controller Designations A and B
The terms A, B, “this controller,” and “other controller,” respectively are used to
distinguish one controller from another in a two-controller (also called
dual-redundant) subsystem.
Controllers and cache modules are designated either A or B depending on their
location in the enclosure, as shown in Figure 4 for the Model 2200 enclosure and
in Figure 5 for the BA370 enclosure.
