Scsi Problems - HP Tc2120 - Server - 256 MB RAM Operation And Maintenance Manual

Chapter 6
Action:
Use the (BIOS) Setup Utility to ensure the CD-ROM drive is bootable:
1. Place a known, bootable CD-ROM in the drive.
2. Review the Troubleshooting Checklist and Boot Device Priority.
3. Reboot the server and run the (BIOS) Setup Utility (press F10 during the boot process).
4. Select the Boot menu and the Boot Device Priority submenu.
5. If necessary, move the CD-ROM up the boot list. This ensures the CD-ROM will boot before any of the
hard disk drives (IDE or SCSI)
6. Save and exit the Setup Utility.

SCSI Problems

Symptom:
· The SCSI Boot Controller BIOS Has Trouble Loading The Boot Logical Drive (NOS drive)
Action:
1. Verify the SCSI boot controller is bannering (displaying) on POST.
2. Ensure that the SCSI boot controller's BIOS is enabled. Check this from the SCSI Setup Utility. To
access this utility, enter CTRL C when a Symbios controller banners on POST or CTRL A when an
Adaptec controller banners on POST.
3. Determine what the boot order is for the HP Server. To verify that the SCSI boot controller board is in
the correct position in the boot order, enter F2 on POST to access the system BIOS Setup Utility. The
boot order can be viewed and changed from this utility. If necessary, change the slot (if applicable) that
the SCSI controller is in to change the location in the boot order.
If the problem persists:
4. Clear CMOS and flash the system BIOS. See the HP Server Operations and Maintenance Guide on the
proper procedure to do this.
5. Repeat step 3.
6. If you installed more than one SCSI controller, try disabling the BIOS on all other SCSI controller
except for the SCSI boot controller. This lets the SCSI BIOS for the boot controller load and prevents
conflicts with the other SCSI controllers. If necessary, remove all the other SCSI controller boards
except the SCSI boot controller until the issue is resolved.
Symptom:
· The SCSI device stop working.
Action:
1. Verify the device banners on POST or is seen in the SCSI Select Utility.
2. Run DiagTools and verify:
o SCSI IDs and any relevant switch settings.
o SCSI bus information.
3. If an accessory board was added recently, check for a resource conflict between the new board and an
existing accessory boards.
o Remove the board and restart the HP Server.
o If this corrects the problem, the new board is either defective or it is trying to use a system resource
used by another SCSI controller board.
