SCSI Problems

Symptom:
•
The external SCSI subsystem does not work after installation
If the external SCSI subsystem does not work after installation, do the following:
1. Review the Troubleshooting Checklist and read Mass Storage Guidelines.
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. Refer to the documentation that came with the SCSI devices for any specific information on
installing them.
4. Ensure all installed SCSI controllers are installed and configured correctly.
5. For any SCSI devices installed in an enclosure external to the Netserver chassis, make sure
that Ultra SCSI is disabled on this controller. SCSI devices external to the Netserver chassis are
supported in Fast SCSI mode only.
6. Check the SCSI cables for problems that may have been caused by recent computer
maintenance, hardware upgrades, or physical damage.
7. Check the ROM BIOS version to make sure it is the most recently issued version. Booting the
most recent version of the HP Netserver Navigator CD-ROM will automatically report if the
BIOS is not current and needs updating ("flashing"). Follow the instructions in the screen to
update the BIOS.
8. Check that the external SCSI subsystem BIOS is being executed properly.
When you start the server, the incrementing count of the RAM appears on the screen. Then
◊ ◊ ◊ ◊
the external SCSI BIOS displays a banner and a copyright notice.
The BIOS then checks for valid devices on the SCSI bus, and reports which devices are
◊ ◊ ◊ ◊
found. If you have installed and configured the SCSI devices correctly, you will see a list
confirming all SCSI devices installed in the Netserver.
If the banner is not displayed, the external SCSI controller is not recognized.
