A
SCSI ID Settings for Drives
Setting a Unique SCSI Address
Each internal drive has a SCSI address that must be unique. If
more than one drive is set to the same SCSI address, the system
cannot communicate with the drives.
When your drive arrives from the factory, all SCSI jumpers may
be attached so that they are not lost during shipment. If this is
the case, the address is set to 7, and must be changed.
TURBOchannel modules and memory modules do not have SCSI
addresses.
This appendix contains an illustration for each of the drives
supported on the DEC 3000 Model 900 AXP system.
