Symptom:
•
The SCSI BIOS has trouble loading
If the NetServer has trouble loading the SCSI BIOS, do the following:
1. Review the Troubleshooting Checklist before you continue.
2. If you installed more than one SCSI controller, make sure that the BIOS of all SCSI controllers
are disabled except for the boot controller. This lets the SCSI BIOS for the boot controller load.
3. Determine what the boot device priority is for the NetServer model. Verify that the boot device is
in the right place in the priority.
Symptom:
• The SCSI subsystem does not work at installation
An incorrect configuration and not faulty hardware cause many SCSI problems. If the SCSI subsystem does
not work after installation, do the following:
1. Review the Troubleshooting Checklist and Mass Storage Guidelines before you continue.
2. Run the DiagTools and verify the integrity of the SCSI buses, and other switch settings on the
external storage devices are correct. Verify that each SCSI device is assigned a unique SCSI
ID.
3. If you don't see the SCSI BIOS banner during NetServer start:
"Symbios, Inc. SDMS(TM)V4.0 PCI SCSI BIOS, PCI Rev. 2.0, 2.1"
"Copyright 1995, 1998 Symbios, Inc."
Check the cable connections.

Check the SCSI termination.

4. Run the Setup Utility or SCSI Configuration Utility and verify the SCSI host bus adapter (HBA) is
properly configured.
The HBA is usually SCSI ID 7.
5. If you installed more than one SCSI adapter, verify each adapter is set to a separate BIOS
address; or disable the BIOS on all of the adapters except one.
6. For each device, verify;
The device has a unique SCSI address.
◊ ◊ ◊ ◊
In general, when selecting an address for a drive (default address is 0), select as low a SCSI
◊ ◊ ◊ ◊
address as possible.
The device's jumpers are set according to the device documentation.
◊ ◊ ◊ ◊
The hard disk activity light cable (for non-hot-swap devices) is properly installed.
◊ ◊ ◊ ◊
7. Check that the primary SCSI hard disk drive is set to the lowest address (usually set to 0). Each
device (the HBA is also a device) must have a unique and separate SCSI ID number. To solve
this problem, simply set the device ID to something other than that of the HBAs SCSI ID (7). If
the device is a boot drive, then the SCSI ID should be set at 0.
8. If another hard disk drive is connected to the SCSI bus, check it for unique address, SCSI cable
connection, and power connection.
