| Hi,
| 
| We have on an old Dell 2850 with 4 SCSI drives, where we put a
| Hardware
| RAID5 on 3 disks and left 1 as spare.
| I dont remember exactly, but the RAID was setup in the BIOS, and when
| installing CentOS6, I just saw "1 drive".
| 
| If it was software RAID, disk failure could be seen in /proc/mdastat,
| and I could simulate failure with mdadm.
| 
| As far as it is hardware ATM, how, at least, to know the state of the
| RAID array? (syncing, healthy,...)
| 
| Thank you.

The IPMI controller if you have one, or the Dell diagnostic tools such as OSMA.  Megacli can report these things back to you.
