I have a proliant ML3xx(not sure exact mode)l with 3 x 250 gb hot swap sata raid 5 hard disks, the middle disk looked as if it was failed as the red light was on. I put in a brand new hp drive today but still the red light showed and ACU it was showing as failed or missing.
I noticed when I took out the disk completely there was a red light showing on the board where the drive connects to the board .
I then tried the disk in the fourth slot which is a spare slot and a green light came on the disk, so it would appear that the connector on the board is faulty and not the drive.
Does anyone know if it is possible to tell the array to use the 4th slot for the disk rather than the 2nd slot which I assume if faulty??
