When connecting multiple SCSI devices in a chain, it is important to ensure the SCSI IDs do not conflict. Each SCSI device requires a unique ID because the ID identifies a physical address on the SCSI bus.
To prevent conflict problems, the SCSI device ID should be uniquely set. However, the methods used to set the SCSI ID will vary, depending on whether the device is a disk or host. For example, with disks, the ID can be set on the hardware.
The ID of a Sun storage enclosure is generally hardwired to a drive position within the enclosure. This method ensures that each position has a unique SCSI ID associated with the position.
Setting the SCSI ID for a host that is a SCSI-initiator is more complex.
