10 6 Troubleshooting
Defective Disc
HP CD-ROM drives in the tower are designed to automatically
switch down to lower speeds when they encounter a defect or a
scratch on the disc, and then to continue to read data at the slower
speed until a new read command is transmitted to the drive.
However, fingerprints, contaminants, or deep scratches on the disc
surface may prevent the drive from successfully reading data.
Perform the disc cleaning procedure on page 2-8.
If the problem persists, test a different disc in the same drive;
if that disc works properly, the previous disc may be defective.
If no disc works properly in the drive, then switch off the server,
wait 10 seconds, then switch it on again (power cycle), and wait
for the self-test to complete and Status to be solid green.
Also verify that the disc is in a supported format (described on
page 10-7). If the problem persists, the drive may be faulty; see
"Isolate Faulty Hardware Component" on page 10-16.
Ejected Disc
HP CD-ROM drives in the HP server are designed to automatically
eject any unreadable disc. HP DVD-ROM drives in the HP server
will eject a disc that is blank or has no table of contents. If a disc is
ejected, verify that the disc is in the tray with the label side towards
the top of the tower (as floor mounted). Or the disc may be blank,
incorrectly written, or damaged. Also verify that the disc is in a
supported format (described on page 10-7).
Test a different disc in the same drive; if that disc works
properly, the previous disc may be defective. If no disc works
properly in the drive, then switch off the server, wait 10
seconds, then switch it on again (power cycle), and wait for the
self-test to complete and Status to be solid green. If problem
persists, the drive may be faulty; see "Isolate Faulty Hardware
Component" on page 10-16.
