Hi,

I'm not sure whether it's a s/w (ADSM) or a h/w question.

I have the following environment:

RS/6000 model E20, AIX 4.1.5, ADSM, SCSI diff. (wide - 16 bits - 68 pins)
card, to which a 3570-B12 (dual headed) in "base mode" is attached. A
3995-A63 (optical) is attached as an additional scsi device after the
second drive of the 3570 (ie: E20----3570 drive#1---3570 drive#2 - 3995).

AIX sees both the 3570 and the 3995 alright. However, the 3570 sems to  have
seems to have problems in thi config. (when using Atape commands). When
I disconnect the 3995 (and put a termintor instead), everything seems ok,
except, of course, that I can't use the 3995 ...


I am not aware of any limitations that do not allow conneting additional
devices after the 3570, and the 3570's operator guide (I did RTFM, and
least here and there...) does in fact suggest such a connection.

1. Should such a connection work (remember, I'm talking without load,
   adsm not using any device, or even running, at that time) ?

2. Any special cabeling between the 3570 and 3995 ? Can you suggest an
   IBM part # for that cable ?

3. Any other idea/suggestion/hint ....


Thanks for any suggestion,

/Zvika
