I also have a Dell PowerEdge 2850 with the PERC 4e/Di Raid card and I found some interesting information tonight that will help us all out. http://www.freebsd.org/news/press.html#story200505:02 Basically, LSI now supports FreeBSD and 5.4 seems to have the updated drivers... so what does this mean? Well, I discovered that the PERC 4e/Di Raid card is the same thing as the LSI MegaRAID 320-2X. So if you go to www.lsilogic.com and go to the download section and find the downloads for the "LSI MegaRAID 320-2x" you will see that there is a "driver" for FreeBSD. Download this file and unzip the contents. Inside there is a file called "MegaRC 1.04.zip" Unzip that and you will have a file called "megarc" make the file executable "chmod +x megarc" and run the command "./megarc -option" This will give you some options that you can play with. So far I've discovered the following useful information: ./megarc -AllAdpInfo This shows all your supported adapters. In my case it found the following: AdapterNo FirmwareType CardType 00 40LD/8SPAN PERC 4/DC I then did this to display the status/configuration of the controller: ./megarc -dispCfg -a0 Finding Devices On Each MegaRAID Adapter...
