I currently have the following setup:

HP DL380 G4 Server
6 x 73GB, Ultra160, 10k, SCSI 80 Pin Drives
Smart Array 6i Controller
RAID 5

One of the drives is failing and needs to be replaced. I have on hand drives that are the same size and type, but are Ultra320, 15k instead. I have verified that these drives work in another system with the same type of drive controller.

When I plug one of these in the system simply reports the drive as being offline and has nothing further to do with it. From what I have read these drives should be compatable.

Should this work at all and if so, what might be preventing it?
