specifications, and data compression for the Compaq Advanced Intelligent Tape (AIT) TM 35 LVD drive. Requirements Compaq recommends equipping the computer with a 32-bit Fast SCSI-2 Controller or higher. Any of these controllers fully support the AIT 35 LVD tape drive. Install the controller before beginning the drive installation, using the documentation included with the controller. IMPORTANT: All SCSI devices on the same bus must either be internal (within the computer) or in an external storage device, but not both. The exception is a CD-ROM drive, which may be internal when other devices are external or vice versa.

Tape Specifications The data tapes must meet these requirements: I Only Standard AIT 35 GB tapes, Advanced Metal Evaporate I Must be one of the following sizes: 170 m (557 ft) or 230 m (754 ft) NOTE: The AIT 35 LVD drive does not support the DDS and EXABYTE formatted tapes. IMPORTANT: Compaq recommends that only tapes purchased from qualified vendors be used. Data Compression The AIT 35 LVD tape drive ships from the factory with data compression enabled for writing. The drive is equipped with Adaptive Lossless Data Compression (ALDC) algorithm. In this mode, data is always compressed when writing to the tape, but the drive is capable of reading both compressed and uncompressed tapes. For the drive to write uncompressed data, you must change the data compression hardware setting. This can be changed by software or using the DIP switches. Consult your backup application software documentation for the data compression enabling and disabling procedure. Figure 1-1. DIP switch settings

Loading and Unloading a Tape Loading a Tape Insert a tape into the slot on the front panel of the drive. As the tape is inserted, the drive takes it and automatically loads it into the drive mechanism. Unloading a Tape The tape can be removed from the drive either via software or the eject button. By pressing the eject button, the tape will rewind and the drive ejects the tape from the slot. Forcing the Ejection of a Tape CAUTION: You may lose data if you force the ejection of a tape. The tape may also end up invalidly formatted, because End of Data (EOD) may not have been written. Force an ejection only as a last resort; never use it as a quick way to eject the tape. By pressing the eject button when the drive is busy, it may take a while for the drive to respond to the request, because the drive will finish the task it is engaged in before it responds. This ensures that the task is terminated in a controlled manner and no data is lost. However, there may be occasions when unloading a tape is urgently needed, even at the risk of losing data. Forcing the ejection of the tape must be performed. To do this, hold the eject button down for at least 5 seconds. The tape is immediately unthreaded and the tape is ejected, regardless of what operation the drive was performing. WARNING: Risk of electrical shock. If tape is jammed inside the drive do not attempt to open this product. Refer all service to a Compaq Authorized Service Provider.

Write-Protecting a Tape The tape has a write-protect switch 2 to prevent accidental erasure of data. Before loading the tape into the drive, position the write-protect switch on the front of the tape. By moving the switch to the right, the tape is write-protected and by moving the switch to the left, the tape is write-enabled. 1 2 Figure 5-2. Tape write-protect switch Memory In Cassette AIT tapes provided by Compaq support Memory in Cassette (MIC) . This feature enables the tapes to store important tape information in memory, which allows faster access to data. MIC tapes can be easily identified by the gold connector pins 1 located left of the write-protect switch. NOTE: Not all AIT 35 LVD tapes have this feature.

Tape Handling and Storage For longer life of recorded or unrecorded tapes, store tapes in a clean environment with these conditions: I Keep the tape out of direct sunlight and away from heaters and other heat sources. I Use the tape in temperatures between 15° C and 35° C (59°F to 95°F). I If the tape has been exposed to extreme heat or cold, stabilize it at room temperature for the same amount of time it was exposed – up to 24 hours. I Do not place the tape near electromagnetic interference sources, such as video monitors, motors, and video or X-ray equipment. Data on the tape can be altered. I Store the tape in a dust-free environment where the relative humidity is between 20% and 80%. For longer cartridge life, store the tape at 20% to 40% relative humidity.

Reliable backup of your system is the product of at least four components: I A reliable tape drive I Quality tape cassettes I Regular backup schedule with backup media stored offsite I Routine tape drive maintenance Compaq tape drives are designed to operate reliably under worst case conditions; however, they require simple routine maintenance to operate efficiently. Regular cleaning is the most essential step in properly maintaining a tape drive and preventing errors. Reliability of Backup Devices The reliability of any backup device is directly related to its duty cycle (the number of hours per day that the device is in use). For example, if a tape drive designed for 1-GB backups is being used to back up a 10-GB computer, the result on that drive will be premature aging and reliability problems.

Importance of Routine Cleaning The tape drive has a cleaning roller built in which prevents and recovers from head contamination. This feature minimizes buildup on the read/write heads so fewer cleaning cycles with a cleaning tape are required. However, Compaq recommends a routine cleaning schedule every 100 hours of use to keep the tape drive in good working order. The drive will also need cleaning when the drive Status LED displays long flashes with short pauses (See Table 5-2). IMPORTANT: Regular cleaning is vital to trouble-free operation of any tape device. Failure to follow recommended cleaning procedures could result in serious damage to the tape drive. When a drive is cleaned according to a regular schedule, one cleaning cycle typically removes accumulated dirt and particle deposits. However, in a dusty environment, or if a regular cleaning routine has not been followed, one cleaning cycle may not fully clean the AIT 35 LVD drive read/write heads. Errors Resulting from Cleaning Neglect Following are some of the errors that can result from failure to observe routine maintenance and cleaning of tape drives: I Dropouts Caused by weak signal strength from dirty read/write heads, a dropout can result in reduced tape capacity and backup performance. I Media errors The backup tapes can be jammed, torn, or otherwise damaged by a dirty read/write head. I Read or write errors Because of a dirty read/write head, data may not have been recorded on the tape during backup. Even if the data is on the backup tape, retrieval may not be possible if the dirty head cannot read the data. I Format failures During backup, data is laid on the tape in a certain format for easy retrieval. A dirty write head can cause format failures, which means that data can be lost or impossible to retrieve. I Bad blocks Because of media damage (see media errors above), the tape may not accept backup data. Also, the read/write head may be unable to retrieve data from bad blocks.

Importance of Compaq Approved Tapes Compaq approved tapes are thoroughly tested to meet high-quality standards. Before Compaq recommends a tape, the quality and reliability of the magnetic media and the tape are evaluated. Do not use an unapproved tape as it may not be compatible with Compaq tape drives. The data tapes must meet these requirements: I Only Standard AIT 35 GB tapes, Advanced Metal Evaporate I Must be one of the following sizes: 170 m (557 ft) or 230 m (754 ft) NOTE: The AIT 35 LVD drive does not support the DDS and EXABYTE formatted tapes. IMPORTANT: Compaq recommends that only tapes purchased from qualified vendors be used. Tape Drive Cleaning Procedures CAUTION: Do not use alcohol or cleaning solution to clean AIT drives. Do not clean read/write heads with a cotton swab. Fibers from a cotton swab can cause permanent damage to the head. 1. Insert the cleaning tape into the drive. The drive automatically takes the tape, loads it, and cleans the heads. 2. When the tape is done cleaning, the drive ejects it. 3. If the drive does not eject the tape and the Status LED is flashing (see Table 5-2), press the eject button, discard the tape, and insert a new cleaning tape. NOTE: This indicates the cleaning tape is exhausted. Throw away the used cleaning tape. Take the tape out of the drive and write the cleaning date on the tape label. This provides a record of how many times the cleaning tape has been used. The cleaning tape typically has a life of 35 cleaning cycles.

Eliminating Resource Conflicts Many of the problems associated with tape drive installation are a result of resource conflicts between the tape drive components and the other components in your computer. Before following the troubleshooting procedures in this guide, complete the system configuration worksheet on the next page. Use the worksheet to identify and correct resource conflicts. Completing the System Configuration Worksheet 1. Run the Compaq System Configuration Utility and select Step 4. 2. Record the switch settings for all option boards on the worksheet in the system configuration section. 3. Remove the computer cover and record the actual switch settings from all option boards in the option board section of the worksheet. 4. Compare the settings recorded on the worksheet. If there are any differences, set the board switches as recommended by the Compaq System Configuration Utility.

Installation Troubleshooting Follow the procedures in this section if the tape drive has not been operational since it was installed in the computer. Turn on the computer and insert the tape. Table 7-2 Installation Troubleshooting Problem Try This Tape light on the tape drive does not turn on. I Make sure the tape drive power cable is connected. I Remove the signal cable from the tape drive. If the light starts working, check for a defective cable, an incorrectly installed cable, or a defective controller. I Replace the tape drive. Tape light on the tape drive turns on, but drive does not respond to commands. Run the Compaq System Configuration Utility from the hard drive or from diskette and restart the computer. Configure all boards in the system, then check the following: I Verify that all installed boards appear in the slot diagram. Add any missing boards. I Verify that the switch settings shown by the Compaq System Configuration Utility match the physical settings used on the boards. Ensure that the board settings match the settings shown by the utility. System Configuration Utility does not recognize the tape drive. I Check the connections of the signal cable. I Check the seating of the controller. I Ensure tape drive power cable is oriented correctly and inserted completely. I If multiple SCSI devices are used, ensure that each device has a unique SCSI ID. I Your drive should be shipped from the factory with all terminators removed. Verify that all terminators have been removed. I If none of these steps solve the problem, then remove, replace, and test each of the following components separately: signal cable, tape drive, and finally the controller.

Quick Checklist Listed below are some hardware and software related items that potentially could cause tape drive failures. These items are covered in more detail under Eliminating Resource Conflicts, Installation, and Resolving Operating Problems. Hardware Make sure the following tasks have been properly completed: I The Compaq System Configuration Utility has been checked for conflicts I The tape drive switches and jumpers have been set correctly I The power and signal cables are connected correctly and the controller is seated properly I For all Compaq computers with multiple devices on a SCSI bus, each device has a unique SCSI ID Software Make sure the software is properly functioning: I The tape drive passes the Compaq Diagnostics test I The controller has been configured using the Compaq System Configuration Utility I The correct software drivers are being used. (Make sure that the operating system driver for the tape drive matches the drive type.) I The version of the backup software supports the tape hardware you are using. If none of these software problems above apply, try reinstalling the tape drive software.

Resolving Operating Problems If the AIT 35 LVD drive worked previously but now does not, try the following: 1. Clean the drive heads. 2. Run the tape drive option of Compaq Diagnostics. 3. Replace the tape. 4. If multiple tape drives are used, ensure that each tape drive has a unique SCSI ID. 5. Your drive should be shipped from the factory with all terminators removed. Verify that all terminators have been removed. 6. Determine what has changed in the system since the last tape backup. a. If the system configuration has been changed, try removing the change to see if it affects the tape backup system. b. If a board or option has been added, check its DMA, IRQ, and port address settings for conflicts. Try removing the board or option. c. If a SCSI device has been added, check for SCSI ID conflicts and proper termination. 7. Check the controller, signal cable, and power cable connections to ensure that they are properly seated. 8. Replace the cables, tape drive, and finally, the controller. Correcting Intermittent Failures If the AIT 35 LVD drive works only intermittently: 1. Clean the tape drive heads. 2. Run the Compaq Diagnostics Utility and the tape drive Diagnostics Utility. Follow the steps listed in the Installation section of this chapter for the Compaq and tape diagnostics programs. 3. If the tape backup procedure starts correctly but then stops with an error: a. Use TEST to check the tape drive firmware revision level. b. If the error occurs on the same file or directory each time, correct any errors that you find with the file system by running a file system utility such as SCANDISK.EXE. If the problem continues with a particular file or directory, remove that file or directory from the backup list.

4. If the tape backup procedure starts correctly, but stops intermittently: a. Check the DMA, IRQ, and port address settings for conflicts. If there is a conflict, change the setting or remove the conflicting board. b. Try using a new tape cassette. 5. Check the Compaq website to be sure the drive has the latest firmware upgrade. If not, upgrade by using one of the methods listed below. Upgrading the Firmware Using the Tape Storage Management Console The Tape Storage Management Console (TSMC) keeps track of all available firmware versions for specific Compaq products. TSMC has two options to get firmware or application updates from the Web. You can use the Download command available in the TSMC program, or use the FDU.EXE program located in the TSMC directory. File Retrieval (FDU.exe) FDU.EXE is a separate program that can be run from outside of TSMC. This program can be run from any Microsoft Windows NT or Microsoft Windows 2000 system to get firmware or application updates. FDU.EXE can be found in the parent directory of TSMC. NOTE: The FDU.EXE program appears in the Start Menu as File Retrieval. Download Command To update using the Download command: 1. Selecting the Download command. You are asked if you want to use the firmware database. Click Yes if you want to use Compaq recommended firmware updates. Click No if you have a specific firmware file that you want to use. 2. If you clicked Yes, several dialogs appear and disappear. TSMC opens the database and compares the list of available updates to the specific information for your device. It then produces a list of firmware versions that you can use for your device. If you have Internet access, the firmware file you select is automatically downloaded. If you do not have Internet access, click on the Use Local Media button and then click OK to browse for the firmware file from a local source.

3. If no firmware versions are available for download, click Skip. TSMC will go straight to the download dialog, where you can manually specify a file for download. CAUTION: Make your selection carefully -- firmware dictates the behavior of your device, and different firmware versions will each make your device behave differently. 4. You will reach the download dialog if you answered No to the 'use database' prompt or if you did not cancel the Available Updates dialog. As the download dialog starts, it communicates with your device to determine the optimal download parameters. 5. Before proceeding be sure to read the following cautions: CAUTION: Do not interrupt the download process or eliminate power to the device while the download process is running. Doing so may render your device unusable. CAUTION: ESL9000 and TL895 libraries use serial port downloads. Make sure a serial cable is attached to the device and your host computer. If a download fails to succeed, TSMC enforces a “forced re-download”. Follow the directions on your screen to complete the procedure. IMPORTANT: The default parameters might be the ones that TSMC selects. You should not change these settings. NOTE: If selecting a firmware file from other than the Internet, it is recommended that you put the file on a hard disk instead of reading it from a floppy. TSMC determines download parameters for you when you select a firmware file. If you must change download parameters, consult with Compaq support personnel. Your tape device may need to be in a specific state to receive new firmware. For example, the media may need to be ejected prior to the firmware download. Check your tape device documentation for specific instructions. 6. After specifying a file or arriving to this dialog after using the firmware database click on Download. Do not interrupt the download process or eliminate power to the device while the download process is running. Doing so may render your device unusable. NOTE: After firmware updates are made to devices, you should close and exit TSMC then re-open it. This will properly update the device (library or drive) information, reflecting the firmware update.

Upgrading the Firmware by Tape IMPORTANT: For a Firmware upgrade tape, contact a Compaq Authorized Service Provider. The Compaq AIT 35 LVD drive allows you to upgrade the firmware, should you need to, using a Firmware Upgrade Tape. Follow the steps below. The process will take at least 3 minutes to complete. CAUTION: Do not disconnect power at any time during the upgrade. Disconnecting power during an upgrade may corrupt the firmware and make the drive unusable. 1. Exit all tape applications before proceeding with firmware upgrade. 2. Verify that the drive is not engaged in any SCSI activity, by ensuring that the Busy and Tape LEDs are off and that the host is not accessing the drive. 3. Insert the Firmware Upgrade tape into the drive. 4. The upgrade process automatically takes place. When the process is complete, the tape will be ejected. Remove it and replace it in its box. Upgrading the Firmware Using the Options ROMPaq The Compaq AIT 35 LVD Drive firmware can be upgraded by downloading the Options ROMPaq from the Compaq website at www.compaq.com or by creating a diskette from the Compaq SmartStart and Support Software CD, version 4.9 or greater. IMPORTANT: Make sure that you select Options ROMPaq if you are downloading or creating a diskette from the SmartStart and Support CD. Do not use ROMPaq for this procedure. ROMPaq is for upgrading Compaq servers and workstation firmware. The ROMPaq utilities must be run from diskette. If you download the utilities from the Compaq website, follow the directions given during the download process to create the diskette. If you use the Compaq SmartStart and Support Software CD, follow these directions to create the diskette: 1. Boot the computer from the Compaq SmartStart and Support Software CD. 2. From the Compaq System Utilities screen, select Create Support Software. 3. At the Diskette Builder screen, select the appropriate option for your computer model. 4. Follow the instructions on the screen to create the ROMPaq diskette.

Once you have created an Options ROMPaq diskette, follow the steps below to upgrade the firmware. 1. Shut down the computer. 2. Insert the Options ROMPaq diskette into the computer diskette drive. 3. Power ON the computer. 4. Press Enter at the Welcome screen. 5. At the Select a Device screen, select the tape drive from the list of programmable devices. This may be the only item in the list. Press Enter. 6. At the Select An Image screen, you will see information describing your tape drive, the date of the existing ROM version, and the date of the latest ROM version. Press Enter. 7. Review the information on the Caution screen. Press Enter to reprogram the option ROM or Esc to discontinue reprogramming and return to the Select An Image screen. 8. A message that says: Reprogramming Firmware indicates that the option ROM is being reprogrammed. Do Not Interrupt ROM reprogramming. CAUTION: Do not interrupt this cycle. Interrupting the ROM reprogramming will leave the firmware in an unknown state and may render the tape drive unusable. You will be notified when reprogramming is completed. 9. When the Options ROMPaq is finished reprogramming the option ROM, press Esc to exit the Options ROMPaq utility. 10. Remove the Options ROMPaq diskette and reboot the computer.
