9.2.3. Tracking down problems
The following list is an attempt to give a guideline for the most
common SCSI problems and their solutions. It is by no means
complete.
- Check for loose connectors and cables.
- Check and doublecheck the location and number of your terminators.
- Check if your bus has at least one supplier of terminator power
(especially with external terminators.
- Check if no double target IDs are used.
- Check if at least one device provides terminator power to the bus.
- Check if all devices to be used are powered up.
- Make a minimal bus config with as little devices as possible.
- If possible, configure your host adapter to use slow bus speeds.
