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 the PAC Management Software to find out the firmware version of the present controller.
From the PAC Management GUI, go to
Storage Manage > 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 system.
