LED Warning Conditions – DDS-DC Drive
The following sections describe actions to take if the LEDs indicate a
warning condition.
High Humidity
If the LEDs display the high humidity signal, the humidity is too high
and the drive does not perform any operations until the humidity
drops.
Self-Test (Failure)
If the LEDs display the self-test (failure) signal, a fault was diagnosed
during the self tests. Note the pattern of the pulses and contact your
local service representative.
Media Wear (Caution)
Hewlett-Packard DDS drives continually monitor the number of er-
rors they have to correct when reading and writing to a tape to deter-
mine tape wear and tape head cleanliness. If excessive tape wear or
dirty tape heads are suspected, the drive warns you by displaying the
Media Wear (Caution) signal on the LED indicators.
If the LED indicators on your DDS-format drive display the Media
Wear (Caution) condition, follow this procedure:
1.
Check the system console for any tape error messages. A hard
error during a read or write operation may have occurred.
2.
Clean the heads with a cleaning cassette (HP92283K) as de-
scribed in the “Cleaning the Tape Heads” section, later in this
chapter.
3.
Repeat the operation you performed when the Media Wear (Cau-
tion) signal displayed. If the Media Wear (Caution) signal still
displays, then the data cassette should be replaced.
