Hi Shawn,
The refurb controller is working just fine, the MSA works fine with one controller that is not the issue. The issue is to revive the bricked controller.
The refurb one has the latest firmware that I could find, and I'm trying to XMODEM the same firmware to the bricked controller.
Partner update does not work as it does not recognize the failed controller, however there is still output via CLI from the bricked controller, so this is not a hardware issue.
Firmware version of the working controller: M114P01
Firmware version of bricked controller: unknown
