4.1.3 Replacing the controller module
In 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 SANWatch to find out the firmware version of the present controller. From SANWatch GUI, go to
Storage Manager > Information > Enclosure View .
WARNING! DO NOT use the controller modules from different models. Each 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, ensure that you shut
down you applications and the system.
