the Smart Array 6i has 2 ports. Port 2 is internal only, and Port 1 has an internal and an external connector. It's not possible to have internal and external devices on the same port. My guess is that you have your disk cage cabled for Duplex. That means port 1 is used internally, and external devices cannot be attached (as the error message says)
Have a look at the Setup and Installation Guide for info on how to cable the server internally for simplex. Then you can use your external port.

Do not use the DAT device on the RAID controller !
It will crash the system OR it will slow down drive performance.

I guess in the DL380 you have two additional embedded (basic) SCSI controllers.
And you have - as described in the answer postetd before - two scsi channels.

Connect on of the scsi channels (cables) to the "basic" scsi controller and attach the DAT to that one !

Or - if there are no other internal scsi controllers - add an PCI scsi controller just for the DAT device.
