4.1.2 Replacing the Controller Module
When replacing a controller in a dual-controller system, ensure that the replacement
controller’s
firmware matches with the controller that you want to get replaced. The replacement provided to you has
the firmware version on the label of the packaging.
Use PAC Mgmt. Software to find out the firmware version of the present controller. From PAC Mgmt GUI, go to
Storage Manager > Information > Enclosure View .
WARNING! DO NOT use the controller modules from different models. Each controller module has
a unique ID which is applied to the host port names. If you insist on using other
models’ controller
modules, you may encounter SAN problems on multiple systems.
IMPORTANT! When removing/installing a controller in a single-controller system or both controllers
simultaneously in a dual-controller system, ensure that you shut down the applications and the system.
To replace the controller:
1. Prepare a clean, static-free work pad or container to place the controller.
2. For replacing a controller in a single-controller system or both controllers simultaneously in a dual-
controller system, shut the system down. Stop all I/O access to the system and ensure all cached
writes have been distributed to disk drives using
firmware’s
Main Menu > System Functions >
Shutdown controller function . Power off the system and turn off the power switches and unplug
the power cords from PSUs.
3. Disconnect all cables from the controller that you want to be replaced.
4. Loosen the screws that secure the
controller’s ejection levers to the chassis.
