SCSI
For more information on SCSI hard drives, see “SCSI Devices” on page 153.
Before installing a SCSI hard drive on your workstation, you must give the hard drive a unique SCSI ID.
All SCSI controllers require a unique SCSI ID (0–15) for each SCSI device installed. The controller
identifies a SCSI device by its SCSI ID number rather than its location. Moving a SCSI device from one
position to another on the SCSI chain does not affect communication between the controller and the
device. The reserved and available SCSI ID numbers for SCSI devices are as follows:
0 is reserved for the primary hard drive (not reserved for the primary hard drive on Linux).
7 is reserved for the SCSI controller.
1 through 6 and 8 through 15 are available for all other SCSI devices.
Once you have given the hard drive a unique SCSI ID, you can install the hard drive into your
workstation.
To remove a SCSI hard drive:
1 Disconnect power from the system (page 73), remove the access panel (page 77), and lay the
workstation on its side with the system board facing up.
2 Disconnect the cables from the back of the hard drive.
3 Lift up on the green drivelock release tab 1 and slide the hard drive 2 out of the chassis at the same
time.
