How to determine RAID controller model

Have a server running Redhat 8. It is an older offbrand server. There is no documentation for it and google has turned up no results. Plus I am unsure how the hardware has been modified by the servers previous owners.

I need to determine what type of RAID controller it is running so that I can get documentation for this controller. I have SSH access to the server. I'd prefer to be able to do this without having to bring the server offline and with out having to go on site, if that is possible.

There are a couple of options...

1) Try doing 'dmidecode' as root.

2) lhinv - Hardware Inventory for Linux

3) Type 'dmesg' and see if your RAID controller shows up there
