You ran out of space and added a eighth disk to your SCSI-I system. When you try to start, the system no longer boots.

What is most likely the cause of this problem?

A.
SCSI-I supports only 8 devices including the adaptor

B.
SCSI-I supports only 6 disks per adaptor

C.
There is a SCSI-ID conflict that causes that problem

D.
You forgot to set the SCSI-ID #8 for the new disk

Explanation:
SCSI-I supports only 7 diskdrives per adaptor, if you need more devices switch to Wide-SCSI (15 drives) or install an additional SCSI adaptor.
