these default values be modified, e.g., to synchronize the subsystem
thresholds with other severs/devices at the same installation site.
5.8 Redundant Parameters
This window provides access to the following options:
1. Redundant Controller Communication Channel:
This is a view-only item in subsystems that come with preset
channels for synchronized cache communications between RAID
controllers. For Fibre-to-Fibre RAID controller heads, this
becomes a configurable option. You may assign specific routes
for communications traffic, such as “dedicated RCC” and
“drive+RCC.”
2. Secondary Controller RS-232 Terminal:
When set to enabled, you can connect a serial cable to the
Secondary controller’s serial port. Note that you can only monitor
the working status of the Secondary controller, and cannot make
changes to system configuration through the Secondary
controller.
