1.3.4 Setting SCSI IDs

1.4 Troubleshooting

1-12
Each device on the SCSI bus, including the host adapter, must have a
unique SCSI ID from 0 through 7. SCSI ID 7 is the preset host adapter
setting, giving it the highest priority on the SCSI bus. Refer to your
peripheral device documentation for instructions on how to determine
and change the ID of each peripheral device.
Caution: The LSI20860 supports only SE SCSI devices. Differential
SCSI devices may be damaged if you connect them to this
host adapter. Refer to your SCSI device documentation to
make sure you are connecting an SE device.
Some potential problems and their suggested solutions are:
During installation, no SCSI devices are found.
1. Check the cable connections and the host bus adapter installation.
2. Ensure that all devices are powered on and terminated correctly.
3. Check that no devices have duplicate SCSI IDs.
4. Make sure INT A is assigned for the PCI slot(s) where your SCSI
host adapter(s) are installed.
5. Make sure the SCSI device driver is installed properly.
The computer hangs or locks up when booting and the SCSI
devices attached are not seen by the computer system.
1. Make sure that all the SCSI devices are configured at different ID
numbers (the boot drive should have the lowest ID).
2. Make sure both ends, but only the ends, of the SCSI bus are
terminated.
3. Make sure the device driver for DOS and OS/2 are listed in the
CONFIG.SYS file and loaded when booting.
