The Logical Unit numbers should be the same on all the drives. The SCSI ID
numbers have to be different for all drives on a SCSI bus. You can add up
to 7 SCSI devices to the SCSI bus (the SCSI controller is the 8th device).
Usually the controller is ID #7.
If no internal drives are to be used, then set the ID numbers of the two
drives (ie: set one to #6 and the other to #5. Sometimes there is a
push-buttom to do this; other times you have to change jumper blocks).
Daisy-chain the drives & remember that the first and last devices on the
SCSI bus must be terminated. If the controller is terminated, than this
counts as the first termination (I don't have any experience with the
A2090A, only SCSI in general). You'll have to terminate the last drive on
the bus. This should do it.
Let me know if you have any questions…I am currently using a HardFrame
with: 1 internal 80MB Quantum, 1 internal SyQuest, and 5 external 600MB CDC
drives.
