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
abbreviated 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
abbreviated to “other” in CLI commands.
Figure 1–3 shows the relationship between “this controller” and “other controller” in a
Model 2200 enclosure. Figure 1–4 shows the same relationship in a BA370 enclosure.
