This appendix describes the SCSI target identification and locations for the SCSI devices in the SCSI Expansion Pedestal as configured at the factory.
This appendix discusses the maximum configuration, as supported by Sun, but the same rules will apply for all available products installed in the SCSI Expansion Pedestal by location.
Appendix B discusses the SCSI target platform and illustrates the correct procedure for setting the SCSI target ID and installing the device target ID jumpers on Sun supported SCSI devices.
When installing or replacing a SCSI device in the SCSI Expansion Pedestal refer to this appendix for the correct location and target ID, and Appendix B to set the jumpers correctly on the device.
The SCSI Expansion Pedestal may contain three drive trays, depending upon the model.
The top tray may contain one or two tape drives or a tape drive and a SunCD, and the two other trays (if installed) always contain hard disks.
The device target ID serves two purposes:
There are two available device configurations for the top tray.
Figure A-1 Tape Drive and SunCD in the Top Tray
Figure A-2 Two Tape drives in the Top Tray
Figure A-3 Four Hard Drives in the Middle or Bottom Tray
The following table shows SCSI device address as determined by SCSI target ID on more than one SCSI bus.
