Installing SCSI Devices

This section describes how to configure and install small computer system interface (SCSI) devices in your system.
SCSI Configuration Guidelines
Although you install SCSI devices essentially the same way as other devices, their configuration requirements are different. For details on
configuring your particular SCSI subsystem, refer to the documentation for your SCSI devices and/or your host adapter card. The following
subsections offer some general guidelines.
NOTE: Dell does not support mixing SCSI and EIDE hard-disk drives in the same system. If your system contains any EIDE hard-disk
drives, do not install SCSI hard-disk drives.
SCSI ID Numbers
Internal SCSI devices must have a unique SCSI ID number from 0 to 15.
When SCSI devices are shipped from Dell, the default SCSI ID numbers for the primary and secondary controllers are assigned as follows:
SCSI controller: SCSI ID 7
l
Boot SCSI hard-disk drive: SCSI ID 0
l
SCSI CD-ROM drive: SCSI ID 5
l
SCSI tape or digital audio tape (DAT) drive: SCSI ID 6
l
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID
number.
