8.4 Locating SCSI Device ID Conflicts
The most common SCSI configuration problem is an ID conflict. Each SCSI
device on a port must have a unique ID from 0 – 15, which cannot be the same as
the host ID or that of any other drive.
Note
By default and convention the host is always at ID
7 and disks start at ID 0. UNIX does not currently
support drives at IDs from 8 – 15.
8.4.1 Two Disk Drives with the Same ID
The most common result of having two disk drives with the same ID is that
neither
of them shows up at the >>>
show dev
command.
8.4.2 Disk Drives with the Same ID as the Host
The most common result of having disk drives with the same ID as the host is
that
none
of the disk drives shows up at the >>>
show dev
command.

In this example a disk drive was set to the host ID of 7. There is actually only 1
disk drive on the bus, but it responds at each ID.
