could you try `lspci -nn`,  this will return the vendor/device ID, which 
will pin down which megaraid it is.

but, I'm afraid the answer is, that hardware is way over 10 years old, 
and support has been dropped from newer OS releases.   Those raid 
controllers require not only specific drivers, but also support 
utilities for monitoring the status of the raids, and configuring them.

The Megaraid family started back under NCR/Symbios in the late 80s, LSI 
acquired what was left of Symbios in 1998, Avago acquired LSI in 2014, 
then merged with Broadcom  in 2016 (as I understand it, Avago acquired 
Broadcom, but then renamed themselves). Sadly, support for legacy 
hardware tends to evaporate in corporate takeovers as its seen as pure 
overhead.
