Troubleshooting 56
Internal system problems
CD-ROM and DVD drive problems
System does not boot from the drive
Action:
1. Be sure the drive boot order is set so that the server boots from the CD-ROM drive first.
2. If the CD-ROM drive jumpers are set to CS (the factory default), be sure the CD-ROM drive is installed
as device 0 on the cable so that it is in position for the server to boot from the drive.
3. Be sure no loose connections (on page 41 ) exist.
4. Be sure the media from which you are attempting to boot is not damaged and is a bootable CD.
5. If attempting to boot from a USB CD-ROM drive, refer to the operating system and server documentation
to be sure both support booting from a USB CD-ROM drive.
Data read from the drive is inconsistent, or drive cannot read data
Action:
1. Clean the drive and media.
2. If a paper or plastic label has been applied to the surface of the CD or DVD in use, remove the label and
any adhesive residue.
3. Be sure the inserted CD or DVD format is valid for the drive. For example, be sure you are not inserting
a DVD into a drive that only supports CDs.
Drive is not detected
Action:
1. Be sure no loose connections (on page 41 ) exist.
2. Refer to the drive documentation to be sure cables are connected as required.
3. Be sure the cables are working properly. Replace with known functional cables to test whether the
original cables were faulty.
4. Be sure the correct, current driver is installed.
DAT drive problems
Sense error codes are displayed
Action: Refer to the Troubleshooting DAT Drives white paper for information on DAT drive sense error codes.
Search for it on the HP website ( http://www.hp.com ).
DAT drive error or failure occurs
Action:
1. Be sure drivers, software, and firmware are upgraded to the latest revisions.
2. Clean the drive at least four times to be sure that the heads are clean and to eliminate dirty heads as the
possible cause of the failure.
