id 2
ID3. Every other device can be set to any number as long as it's not in use. It is a recommended practice in IT comunity to set the scsi ID number for CD-ROM drive to 3.
ID 3
The ID number which is traditionally assigned to the SCSI controller is ID 7. ID 7 is given the highest priority during bus arbitration.
Assign each SCSI device a unique ID number
The SCSI logical unit number for boot devices is almost always zero(0).Matt Friend
The host adapter is assigned SCSI ID 7, which has the highest priority over all other devices.
You change the ID of one of them. You change the ID of one of them.
8 or 16 depending upon the SCSI hardware being used. In a narrow bus, you can use a SCSI ID of 0-7, and in a wide bus, you can use 0-15.

When assigning IDs to SCSI peripherals, ID 0 should generally not be used for devices other than the SCSI host controller itself. This is because ID 0 is typically reserved for the SCSI initiator, which is responsible for sending commands to other devices on the bus. Using ID 0 for other peripherals can lead to conflicts and communication issues within the SCSI chain. It's best to allocate IDs 1 through 6 or 7 for other devices, depending on the SCSI standard in use.
Multiple SCSI (Small Computer System Interface) devices are connected using a daisy-chaining method, where each device is connected in series along a single SCSI bus. Each device is assigned a unique SCSI ID, typically ranging from 0 to 15, allowing the SCSI controller to communicate with each device individually. The bus can support various devices, such as hard drives, scanners, and CD-ROM drives, as long as the total number of devices does not exceed the bus's capacity. Additionally, SCSI terminators are used at each end of the bus to prevent signal reflection and ensure stable communication.
