I finally got a cable made to connect both the Quantum drives (a 40S and
a 105S) to my 2091. When I connect it and power up, though, my 2000
only recognizes the 105S. Both hard drives work fine when connected
independently, and neithe fried when I connected them up together, so
I don't think the cable is bad. I did take the terminator packs out
of my 40S and put them in the 105S as the 2091 manual said I should.
I also changed jumper 5, option 1 on the 2091 to on, so the controller
would recognize more than one SCSI drive. Is there anything I missed?
I did not get a manual with the 105S (bought second-hand) so if it
needs a unit number change or something, I don't know how to do it.
Any help or suggestions appreciated!
Kurt

Is there anything I missed? >I did not get a manual with the 105S (bought second-hand) so if it First of all, jumper 5.1 is NOT so the 2091 can recognize multiple drives, it's to allow multiple logical units to be recognized at EACH physical SCSI address. With the Jumper in the off position the controller expects a maximum of ONE SCSI device at each of the 7 available addresses (0-6). With it on, it will attempt to address up to 8 (0-7) logical units (LUNs) at each of the 7 available SCSI addresses. The device at a given address would need to be a controller capable of decoding the LUN addresses and be connected to multiple drives that would all be at address x LUN x allowing up to 56 drives on the 2091. Your configuration however has each of the two drives as separate PHYSICALLY addressed devices (or at least they should be) and this jumper would have no effect. You need to be sure that each drive is strapped for a different SCSI address (on the drive itself) to have them both on the 2091 at the same time. Since you say either one works alone but the two don't work together, I suspect they are at the same address.

Probably to (re?)move a jumper on one of the drives to give it another SCSI address. Do they show up as the same unit when connected independently? If so, this is the matter.

The first disk in the chain has a flag on the RigidDiskBlock to tell it that there are no more drives past its address, so the driver doesn`t look. Saving changes erases the flag from the first drive and moves it to the second. Steve

Steve,
I wnated to reply to you to let you know your answer was the
solution. Thanks!
Does anyone know why none of my replies or e-mail to CBMVAX never make
it there NOR do they bounce back to my account here?
