Replacing The Controller Module(S): Single / Dual / Simultaneous Upgrade - Infortrend EonStor GS 3000 Series Hardware Manual

Replacing the Controller Module(s): Single / Dual /
Simultaneous Upgrade
WARNING
Controller firmware MUST be identical for proper functionality.
DO NOT mix controller modules from different models. Each controller has a unique
ID which is applied to host port names. As the result, you may encounter SAN
problems with identical port names on multiple systems.
When removing a RAID controller from a Single-Controller system, ensure that your
applications have been shut down beforehand.
Controller firmware MUST match so before you replace a controller in a dual-
controller system, please check if the firmware of the operational controller matches
the replacement controller sent to you. The replacement controller sent to you will
state its firmware version with a label on the packaging. To find out the firmware
version of your operating controller, use Storage Manager > Information > Enclosure
View in EonOne (please refer to the EonOne Manual for details).
To update the firmware, please refer to the following:
a. EonStor GS EonOne User Manual on Upgrading the Firmware
b. Firmware Manual on System Functions: Upgrading Firmware
