8.2.4Solving Installation Problems

The problems that arise in most installations are described below.

Unstable Termination

This occurs when there is a passive termination with Fast-SCSI devices on the bus.

Incorrect Termination

This occurs when there are too many devices terminated, or when the SCSI bus cable ends are not terminated.

Cables

Avoid using homemade, short, flat ribbon cables with bad contacts or cheap cables. Do not mix round cables with flat cables.

Cable Length

Ensure that the cable length is within the limit specified in the standard, and avoid using cables that are too long to support the transfer rate.

Device ID Conflict

This occurs when a new device is added with a SCSI ID identical to an existing device on the bus.

Missing TRMPWR

This occurs when the host adapter or at least one of the devices on the SCSI bus does not supply termination power.

Missing Software Device Driver

Some host adapters do not install support for SCSI drives as an expansion BIOS. In this case, load an additional driver for your operating system after the system boots. Note that this configuration cannot boot from the SCSI drive.
