I have 2 SCSI U320 hard drives for my server that I am having an issue with.

Both drives, when installed into the server power up, and spin up fine, but, they are not recognized when it comes to trying to configure them.

I would have thought from the documentation that the default configuration would work, but, it does not.

I know the J6 would be the configuration jumper, but, am not up enough on servers to know which SCSI ID to use based upon which position I have it in the chain.

I would also assume that I would need to remove the resistor(s)? The current drives I have in the server do not have configuration jumpers. These are the only 2 in the batch of 10 that came in my lot have have them.

Do these need jumpers for properation?

No. In order to enable hot-swappping those drives feature SCA (Single Connector Attachment), which is a single 80-pin connector that carries power, data and configuration signals, meaning the IDs are set by the backplane they are connected to. Note also that there are no resistors to remove or attach to these drives. You'll want to consult the documentation for that server to see how the SCSI backplane should be set up and configured.

This is exactly what I thought.

I have 2 of these drives that remain unrecognized.

The rest of the drives I have (not the same brand) work fine.

I've done no configuration so to speak of the backplane, I've just slid the drives into the slots, powered on the server, and attempted to configure RAID.

It is at this point where the controller is not seeing these drives.

The "green" power light is lit, but, the "green" access light never does light.

It sounds like those drives may be defective. Scott.
