I have a dedicated server with 4 hdd and RAID 10, with Cent OS 6.4
How can I check if RAID is really enabled. I'm in doubt because on another server with RAID 10 enabled, I can see in /dev sg0 sg1 sg2 sg3 sg4, and with the command smartctl -d scsi --all /dev/sga1 for example, I can get info about the disks.
In this new server, I don't have this.
Is there any other way to check if it really have RAID enabled?
