Cisco SFS 3012R Server Switch Controller Module
The following points apply to the controller modules:
•
Each Cisco SFS 3012R Server Switch comes with one active controller and, optionally, one warm
standby controller.
•
Upon power-up, the controller in slot 1 becomes the master (active). The controller in slot 14, if
present, becomes the standby.
•
The startup configuration file can be synchronized between the active and the standby controllers.
The Command Line Interface (CLI) prompts users to synchronize the controllers.
•
When the master controller fails or reboots, the standby controller automatically takes over as the
new master. All I/O modules (InfiniBand switch modules, Fibre Channel gateways and Ethernet
gateways) reboot when a failover occurs.
•
Users can force a fail-over with the Element Manager graphic user interface (GUI) or with the CLI.
•
The software upgrade/install process upgrades both the master controller and the standby controller
at the same time. You do not need to upgrade them separately.
•
A subnet manager (SM) runs on each controller module. The SM can manage a single
Cisco SFS 3012R Server Switch or redundant Cisco SFS 3012R Server Switches.
