DD890 SAS Controller Module Firmware

Hi,

I recently got my hands on a decommissioned DataDomain 890 hardware to play around and learn with. No DDOS was left on the system.

Trying to update the included SAS31601E to latest firmware using standard tools I accidentally "cross-flashed" the integrated SAS (Raid?) Controller module (the one where the head's internal hard drives are connected to) instead which consequently now sufferes from personality disorder and falsely claims to also be a SAS31601E.

Is there a way to get my hands on a working firmware for the SAS Module? Could even be LSI or the like as long as it fits.

Thanks in advance!

Alex
