Did you reboot the system without the DDS

o Try the following command: .
What did it report?

o Check /var/boot.log and see if there are
any entries against st0.

o Check /var/messages and see if there are
any entries against st0.

If there are NO OTHER SCSI single ended
devices on the bus, OR they are not in use,
you can try to restart the controller.

o Find the name of the controller that
the DDS4 is on. Check an old copy of
/var/messages if you don't know.

o Make sure that the DDS4 is online.

o

o Do a ./[your_controller's_name] stop

You should get an "OK" in the status field.

o Do a ./[your_controller's name] start.

You should get an "OK" in the status field.

o Do a .

You should see a report as to its status.
