Hi,

Well, i've got some trouble to connect 2 PowerEdge 2550 under Linux 7.0
(2.2.16-22) on the same SCSI Bus.
I'm using the following HW :
 - 2 AHA 39160 on each servers,
 - one disk array with 2 HD 18,6 LV on each channel B (Full LVD, no
Ultra/SE).

The 39130 ID  is set to ID7 (default) on server A and to ID8 on server B.
'Bus Reset' at boot is disabled.

Linux is running on both servers (and fine when there are no disk mounted
from the share bus).

Actually, the systems can not run together as i got  scsi time-outs,
errors on the shared bus. Also, the other controller does not appears in
devices list connected on the local SCSI controller (is it normal ??)
I think that one of the controllers must be set as target mode. How can i
do that ? is there any parameter to include at aic7xxxx module load ?

Thanks for Help.
