RAID setup on Fedora 3.8

[Khaled]

Hello,

I need to find out further information about the RAID setup on a backup
server running Fedora 3.8; unfortunately the person who set up the system is
no longer available. Can anyone help me with RAID in regards to Fedora, i.e.
commands/files with more information on the RAID setup, and anything else
anyone may think to be useful.

I am trying to determine whether the system has hardware/software RAID, what
level is setup,  and hopefully configure RAID in the future.

So any help is appreciated.

Kindly,

Khaled
