Multiple LUNs for tape drive

DEC Alpha 3000/600
Just upgraded to DU 4.0b from 3.2

At halt prompt, a s'ho dev' shows that our old Exabyte 8200 drive is now
recognized as 8 (0-7) independent devices, one for each Logical Unit
Number. Building the kernel of course generates a /dev/*rmt* for each
one (eg. rmt0, rmt1, rmt2, ... rmt7).

Accessing the drive (eg. vdump) is noticably slower.

How did that happen? Why would I be seeing this?
