Replacing The Controller Module(S): Single / Dual / Simultaneous Upgrade - Infortrend EonStor DS 1000 Gen2 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 controller from a single-controller system, ensure that your
applications have been shut down beforehand.
Controller firmwares MUST match 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
SANWatch (please refer to the SANWatch Manual for details).
To update the firmware, please refer to the following:
a. EonStorDS SANWatch User Manual on Upgrading the Firmware
b. Firmware Manual on System Functions: Upgrading Firmware
