Controller Designations “This Controller” and “Other
Controller”
Some CLI commands use the terms “this” and “other” to identify one controller or the
other in a dual-redundant pair. These designations are a shortened form of “this controller”
and “other controller.” These terms are defined as follows:
■ “this controller”—the controller that is the focus of the CLI session. “This controller”
is the controller to which the maintenance terminal is attached and through which the
CLI commands are being entered. “This controller” can be shortened to “this” in CLI
commands.
■ “other controller”—the controller that is not the focus of the CLI session and through
which CLI commands are not being entered. “Other controller” can be shortened to
“other” in CLI commands.
Figure 1–3 shows the relationship between “this controller” and “other controller” in a
Model 2200 enclosure, and Figure 1–4 shows the same relationship in a BA370 enclosure.
