SCSI Device Problems
Problem
Action
The SCSI devices do not
work.
Check these things first if an error message indicates that the
software programs cannot find a SCSI device (for example, a
CD-ROM drive or hard disk drive) connected to the SCSI bus:
1. Be sure your computer is docked.
2. Be sure that termination is correctly set for all devices on
the SCSI bus as described.
3. Be sure the cables connecting the external and internal
SCSI devices and the host adapter are attached securely.
Also be sure the pin-1 orientation is correct for internal
cables. If all connections are secure and if you have ruled
out other possible problems, try replacing the cable.
4. Be sure CD-ROM drives and other SCSI devices are
attached to a power source and are turned on.
Verify that:
1. If all of the SCSI devices do not work:
a) For external SCSI devices, check that the SCSI
terminator is installed correctly at the last device.
b) Ensure that the SCSI device driver is installed correctly
by referring to Appendix B.
c) Run the expansion unit diagnostics and the “SCSI
subsystems” diagnostics in the Option Diskette.
d) If you have a known-good drive, attach only the good
drive to the SCSI connector, and then run the test to
verify. If the drive runs without errors, the SCSI
controller in the docking station is working correctly.
Suspect one of the drives.
2. If the only one drive in a daisy chain does not work:
a) Run the drive test to verify the drive operation. Follow
the messages from the test.
b) Ensure that the SCSI settings are correct by referring
to Appendix B.
