About 4 years ago, I tried to install CentOS 6 on a Supermicro Server with SCSI drives using a LSI raid system.  I could never figure out or find a way to make the installation disc of Centos 6 identify the SCSI drives.  The installation disc for Centos 5 identified the SCSI drives without a problem. I finally gave up on Centos 6 and installed Centos 5 and the system has worked very well for the last 4 years.

Now that Centos 5 has been retired, I would like to install Centos 7 on this server.  Does the install disc for Centos 7 have the same issues with SCSI drives as Centos 6?  Has anyone used Centos 7 on SCSI drives, or am I going to need to get an upgrade of the server?  The server is working great.

Please note that I installed CentOS 7 on a machine with an LSI Ultra 320 SCSI card in it and I don’t remember having any problems. But there again, the OS on that system is installed on a separate SAS MegaRAID drive and the SCSI is just used for user files, so I never paid much attention to it during install.

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.
