I'm sorry but but it seems I got something wrong.
I checked again and found that the non-disconnect-capable tape drive on one scsi-host does not
interfere with the devices on the other host. Only when hd and tape is on the same host I get a
blocking hd when trying to read the tape (and hd LED/cdrom LED and tape LED is flashing)! When
reading the tape connected to the Adaptec host (with "allow disconnect" disabled) I
simultaneously can work with hd connected to the Tekram host.

Regards,
Roland Boden
