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