2.4Setting SCSI Device IDs

Each device and host adapter on the SCSI bus must have a unique SCSI ID. It is recommended that the Host Adapter be left at its default ID of 7. If it is necessary to change the Host Adapter ID, refer to Table 3-1, Parameter Settings Quick Reference Chart.

On systems that do not use the on-board BIOS Configuration utility refer to the software descriptions for instructions on changing SCSI IDs. All Intel-based systems use the on-board BIOS utilities; Alpha-based systems use AlphaBIOS for Windows NT and SRM console for DIGITAL UNIX and DIGITAL OpenVMS.

The Host Adapter supports SCSI Configured AutoMatically (SCAM) protocol, which assigns SCSI IDs automatically and resolves SCSI ID conflicts. Devices that support the SCAM protocol do not need to be assigned a SCSI ID manually. Because SCAM is a recent addition to the SCSI specification, many devices do not yet support the protocol and their IDs must be configured manually (refer to the device documentation). SCAM support is enabled by default; refer to the BIOS configuration utility instructions if you need to disable SCAM protocol.

NOTE

On a 16-bit SCSI bus each device must have a unique SCSI ID from 0 to 15. Since the Host Adapter default ID is 7, all other devices on the bus should be given IDs from 0 to 6 and 8 to 15. Refer to the device documentation for instructions on setting the SCSI ID for that device (not all operating systems currently support SCSI IDs above 7).
