Troubleshooting on the SCSI Controller
Most problems with the SCSI controller occur when new SCSI devices are
connected up to the SCSI bus (termination problems, for example). If you are
having problems with the SCSI controller or SCSI devices connected to it,
check the following:
•
Do all the SCSI devices have a power supply?
•
Are the SCSI and power supply cables correctly plugged into the SCSI
device?
•
Is the SCSI cable correctly plugged into the SCSI connection of the
controller?
•
Does each SCSI device, including the SCSI controller, have its own SCSI
ID?
•
Are the SCSI devices and SCSI controller properly terminated?
•
Is parity checking either enabled or disabled on all SCSI devices
connected up to the SCSI bus?
•
Was the device switched off and on again after any changes to the BIOS
setup or SCSI setup or SCSI device settings?

SCSI BIOS Messages
When you switch on the SCSI-BIOS, the following messages may appear
during system startup:
Device connected, but not ready
The SCSI device connected to the Ultra Wide SCSI controller is not reacting
to commands from the SCSI controller. Switch Send Start Unit Command in
SCSI-Setup for the relevant SCSI device to Yes. If the message continues to
appear, read your SCSI device documentation to find out how to set the SCSI
device.
Start unit request failed
The SCSI-BIOS was unable to pass on a power up command (Start Unit) to
the SCSI device. Call SCSI Setup and send the Send Start Unit for the
relevant SCSI device to No.
Time-out failure during ...
A time limit has been exceeded. Check the SCSI bus termination. Disconnect
the SCSI cables from the Ultra Wide SCSI controller and restart the system.
If the system starts successfully, check the SCSI cable. One of the SCSI
devices may also be faulty. Check the SCSI devices.
