I recently installed Ubuntu Server 14.04 an HP ProLiant ML350 Generation 6 (G6) server, that used run windows, which appears to have RAID controller:
The Ubuntu Community Help Wiki says:
Hardware-RAID: A special controller used to build RAID. Hardware RAID is generally faster, and does not place load on the CPU, and hardware RAID can be used with any OS
But I'm not certain if this means the hardware will do things automatically, or if there's something I have to configure.
When I check:
root@webserver:~# cat /proc/mdstat
Personalities :
unused devices: <none>
It doesn't appear as though anything is there.
This is the first server I've ever configured a server, and I'll confess I was ignorant to what RAID was when I installed the OS, so my question is do I have to configure RAID now or is the hardware doing everything automatically? If I still need to configure it, how do I do that without re-installing the OS?
