SCSI disks conflicts on ADAPTEC 29160
I have a PCI ADAPTEC 29160 SCSI card on my PC with an internal SCSI disk (ID=6) booting Linux REDHAT7.3.
I wanted to add an external SCSI disk (ID = 2) on this SCSI.
When I try to reboot the system, it doesn't recognize the boot disk and tries to boot on the network.
It seems to be a conflict between the disks and I don't understand why. I already have an external DAT drive on this SCSI (ID=3).
Thanks if you have an answer.
