If a computer has two SCSI cards how does the OS decide which is c0 and which is c1?

UnixWare 7/OpenServer 6 starts with IO address. For example a mixture of IDE and SCSI would be as follows.

IDE Primary Controller would be c0.
IDE Secondary Controller would bd c1.
SCSI Controller would be c2.

Usually SCSI controllers are choosen the same way they are listed as the BIOS loads. You may be able to modify this behavior in your SCSI BIOS. See the SCSI HBA manufacturer for more information.

    You may also be able to modify the loading order in the dcu.
    There's a TA or a doc in the search engine about it.

    You may get some info from resmgr or from sdiconfig -l.
