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. -- RMA.

I have a different system, a HP Proliant ML110 00:1f.2 RAID bus controller: Intel Corporation 82801GR/GDH (ICH7R/ICH7DH) SATA Controller [RAID mode] (rev 01) any hints for me? -- Q: How do you keep a moron in suspense?
