Resumen del manual


Cassette LED Drive LED Eject Button Figure 5–1. DDS Drive Controls and Indicators LEDs (light emitting diodes) indicate different activities or problems that occur with your workstation hardware LEDs – DDS-DC Drive This section describes the LED codes that are displayed. The front panel has two colored LEDs: the Cassette Light and the Drive Light. A green light indicates normal operation, and an amber light indicates a warning condition. Pulsing shows activity between the drive and the SCSI bus. If the Cassette Light (left LED) shows steady amber, it means that the cassette is write-protected. If the Drive Light (right LED) shows steady amber, this indicates a fault condition. Table 5–1 lists the LED codes and their meanings. Table 5–1. LED Display Codes – DDS-DC Drive Cassette Drive Light Light Meaning Cassette (un)loading Cassette loaded/online Cassette loaded/activity Cassette loaded/offline Write-Protect States Cassette (un)loading Cassette loaded/online Cassette loaded/activity Cassette loaded/offline Error States Media wear (caution) High humidity Self-test (normal) Self-test (failure) Key OFF Green Amber Pulsing Green Pulsing Amber Pulsing Green and Amber 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 errors they have to correct when reading and writing to a tape to determine 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 described in the “Cleaning the Tape Heads” section, later in this chapter. 3. Repeat the operation you performed when the Media Wear (Caution) signal displayed. If the Media Wear (Caution) signal still displays, then the data cassette should be replaced. 4. If you are performing a backup from disk to tape, discard the data cassette and back up your files using a new data cassette. 5. If you are performing a restore from tape to disk, complete the restore, then discard the data cassette and back up the files to a new data cassette. LEDs – DDS-2 The front panel has two colored LEDs: the Tape Light and the Clean/ Attention Light. The Tape Light flashes green to show activity (loading, unloading, reading, and writing). Steady green means a cartridge is loaded. The Clean/Attention Light flashes amber to indicate head cleaning is needed or a cartridge is near the end of its life. Steady amber means a hard fault. Table 5–2. LED Display Codes – DDS-2 Drive Tape Clean/ Meaning Light Attention Activity – load or unload Activity – read or write Cartridge loaded Cleaning needed Fault Key OFF Steady Green Steady Amber Flashing Green 1/2 sec on, 1/2 sec off Flashing Amber 1/2 sec on, 1/2 sec off Fast Flash Green 1/4 sec on, 1/4 sec off Any Any Data Cassettes Media Life HP DDS data cassettes are currently specified to 2000 passes over any part of the tape under optimal environmental conditions (50% relative humidity, 22 degrees C). During a tape operation, any one area of the tape may have multiple passes over the heads. This translates into approximately 200 to 300 backups or restores. Under certain conditions, the life of your data cassette is less. Replace your data cassettes after 100 backups or restores if your operating conditions meet any of the following criteria: • The relative humidity in your operating environment is consistently less than 50%. • You know that the backup software you are using makes multiple passes over sections of the tape during backups or restores. • You notice that when you do backups and restores the tape stops and starts frequently. Cleaning the Tape Heads Clean the heads of your tape drive after every 25 hours of tape drive use or if the Media Wear (Caution) signal is displayed on the LED. NOTICE: Only use HP Cleaning Cassettes (HP92283K) to clean the tape heads. Do not use swabs or other means of cleaning the tape heads. Follow this procedure to clean the tape heads: 1. Insert the cleaning cassette into the drive. The tape automatically loads the cassette and cleans the heads. At the end of the cleaning cycle, the drive ejects the cassette. 2. Write the current date on the label on the cleaning cassette so that you know how many times...
