L&TT assembles these tools into a single and convenient program. • “Software features” (page 9) • “What's new” (page 10) • “Known issues and limitations in L&TT 4.
data is presented in a more useful format. Reports and support tickets are generated on all operating systems supported by L&TT. • Automatic notification of web updates—If a connection to the Internet is present and web updates are enabled in the tool preferences, L&TT automatically informs customer of the following updates, if available, each time the program is started: ◦ New versions of L&TT. ◦ New firmware files for connected devices. ◦ New device-specific functionality for connected devices.
• • Operating system specific ◦ Support for Windows 2012 R2 ◦ Support for Windows 8.1 ◦ Support for Mac OSX 10.9 Generic to tool ◦ Added message to inform users about the result log. ◦ Added more clarity for representation of time in event logs. ◦ Added a warning message for shutting down backup applications at the start of the application. Known issues and limitations in L&TT 4.
• In a library with mixed drive technologies, drive firmware cannot be downloaded from the library firmware download screen. Each drive must be selected individually for download (Future enhancement). • If a device is in a 'Not Ready' state, L&TT may not be able to perform all diagnostic functions. Most devices are only very briefly in this state, but some libraries can take a significant amount of time after power-up or after a firmware download before becoming ready.
operating system has performed its own rescan and logically moved the device after the update. If this happens, use L&TT rescan to locate the device. In these cases the firmware update is successful. Supported products and operating systems For a complete listing of compatible products, see the specifications page: http://www.hp.
2 Using L&TT on Windows • “Installing L&TT” (page 14) • “Using the graphical user interface” (page 15) • “Managing firmware ” (page 25) Installing L&TT The Windows version of L&TT uses the InstallShield application. InstallShield allows you to choose the installation directory and select other options. It also sets up shortcuts to launch the application in the Start menu and on the desktop.
3. Click Next. Read the program license agreement and click Yes to accept the terms of the license agreement. 4. Read the readme file for any last-minute changes to the documentation, then click Next. The Select Features screen is displayed. 5. Select the desired components to install and click Next. 6. Select a destination location to install the program. You can accept the default location or click Browse to install to a different location. After choosing the destination location, click Next. 7.
Starting L&TT 1. 2. Launch the HP L&TT by double-clicking the L&TT shortcut icon on the desktop or click Start > Programs > HP Library and Tape Tools > HP L&TT. Login with the UserName and Password. NOTE: 3. The default username and password is administrator and administrator respectively. Click Sign In. The HP L&TT Startup screen is displayed. The Startup screen gives you the opportunity to exit the application if it was started unintentionally and before any SCSI bus activity occurs.
SelectingSkip Device Scan, will skip the hardware scan and the I/O Mode buttons are disabled. With this mode, no devices will be listed on the main screen. Click the Rescan button in the main screen to scan the connected devices. NOTE: Selecting the Skip this dialog in the future checkbox on the Startup screen will perform a full hardware scan. To re-enable the Startup screen and change the scan option, select Preferences from the Options menu.
Additional device scan considerations After the initial scan is complete and saved, future full system hardware scans become unnecessary in most cases. You must perform a hardware scan after any of these actions have occurred (Windows in NT Miniport I/O mode of operation): • After the hardware configuration is changed. • After power cycling more than one of the tape drives on the system. • After updating firmware in more than one of the tape drives on the system.
Skip this dialog in the future If this checkbox is selected when you click Continue, the Startup screen is not displayed on subsequent uses of L&TT. The program will continue to use the settings that you selected the last time the Startup screen was viewed. To re-enable the Startup screen, select Preferences from the Options menu. Check the Display initial dialog at startup option and restart L&TT.
Application window layout After the I/O mode is selected, click Continue on the Startup screen. The L&TT main screen is shown as in Figure 5 (page 20). The main screen is divided into three sections: • Taskbar • Device list • Device information Figure 5 L&TT main screen The three sections of the L&TT main screen are: 1. Taskbar—This section contains buttons that provide quick access to the main functions of L&TT and to the online help system as shown in Figure 6 (page 20).
determining the cause. When the scan completes successfully, the device list automatically switches to the By Product tab. The Scan tab allows you to rescan the bus. If any devices are hot-swapped or powered on after the OS has booted, in most cases, the rescan feature can discover those devices without rebooting the system. CAUTION: Swapping SCSI devices, including either connecting and disconnecting cables or terminators or both can hang or crash the system.

This provides a cartridge (media) inventory for all the drives and slots. The current status (full or empty) of all the storage elements, bar code number (if bar code reading is available), and media type are displayed here. For more information on the drives within the library, select the Drive Information tab.
Get files from web functionality The Windows version of L&TT offers comprehensive firmware management functionality that finds and downloads firmware from the HP website. This functionality obtains the most up-to-date information about all available firmware files directly from the HP website. It then compares this data set against the list of devices connected to the system and the current firmware revisions present in those devices.
Firmware files can be obtained in three ways: 1. Select the device in the device listing and click Firmware on the main toolbar. On the Firmware screen, click Local Files tab, and then click Get Files from Web button at the bottom of the tab. The downloaded files are automatically placed in the Firmware directory. 2. From the L&TT menu, select Get Files From Web from the File menu. The software links to the L&TT firmware FTP site and allows the selected firmware files to be copied to your system.
Uploading firmware to devices Before updating any firmware files, you must acquire the latest firmware files and ensure that they are placed in the Firmware directory. To upload firmware to a device: 1. Click the device to update in the device list. 2. Click Firmware on the main toolbar. 3. On the Update Firmware tab, select the device to update firmware.
NOTE: With several products, after the firmware file is selected, a message is displayed to inform the certain requirements such as important prerequisites for updating with the new firmware, or noteworthy functional changes (such as a new LED sequence). Be sure to read any such messages and take appropriate actions.
which the product ID does not match the desired firmware file (and the ID may also need to be updated): • ◦ When a library is being updated from one drive technology to another. ◦ when the device has a firmware revision string format that differs from that in the firmware file, and the tool cannot determine whether it is newer or older. If incompatible firmware is sent to a device, an error message is displayed.
5. 6. If any options are available for the selected test, the Options button is enabled. Click Options button to review and set the desired options. When you click an option the description of the option is shown. To return all of the options to their default values, click Defaults. Click Start Test button to start the test. Viewing results When the test or utility is complete, L&TT shows preliminary results of the test.
Figure 15 Email Test/Utility results Aborting a test The selected L&TT tests can be stopped before they complete. Check the test description to see whether the test can be terminated. NOTE: Some tests can take several minutes to stop after they are terminated.
For tests that can be terminated, the Start Test button changes to Abort Test as shown in Figure 16 (page 32). Figure 16 Aborting Test button Click Abort Test. The L&TT will attempt to abort the test, which can take 10 – 20 seconds or more. Once the Abort button is clicked, the button is greyed out and cannot be clicked again. NOTE: • If multiple drives are selected, the tests will run in parallel. • Some tests can take several minutes to stop after they are aborted.
Figure 17 Utility screen For detailed information about the utilities screen, as well as information about how to run the utilities, see “Tests”. Using the support ticket screen A prime feature of L&TT is the ability to generate reports and support tickets. L&TT can automatically generate a support ticket based on information that the program determines about the system. In the event of a hardware problem, a report or support ticket can provide vital information to help diagnose and resolve the problem.
Figure 18 Support ticket generation screen NOTE: In addition to the above options, the bottom section of the support screen provides resources for finding support on the web. Click any of the buttons in the Support Resources on the web section of the screen to a browser window and view the corresponding website.
(Home, End, Page Up, Page Down, and the arrow keys), the Windows scroll bars, and the mouse to navigate through the document. To print the report or support ticket, select File > Print from the menu bar within the report viewer. To view the saved support ticket, the .lzt file using Windows Explorer, or use the Load command on the L&TT File menu. NOTE: To view or email the individual files, rename the .lzt file so it has a .tar file extension and use WinZip to extract the files to a single directory.
Figure 19 Email Support Ticket dialog box Prerequisites Before L&TT can email a report or support ticket, you must either have a MAPIcompliant email program (such as Microsoft Outlook or Outlook Express), or you must set up an email account through the Windows Control Panel or Internet Explorer. For more information about setting up an email account, see “How do I configure e-mail to send support tickets?” (page 155).
From the Support screen, click Send Support Ticket by Email to send the report or support ticket by email to an HP support center (or other destination). Clicking this button s a form that allows you to provide all the necessary information. Complete the form and click Send. NOTE: Using this option does not save a copy of the support ticket locally, so you are advised to click Save Support Ticket to save a copy for future reference.

Installing L&TT for HP-UX HP-UX installation prerequisites Software dependencies/prerequisites • Devices do not need to be claimed by the operating system with ioscan for L&TT to access them. • The sctl driver must be installed for L&TT to access the device you want to test. L&TT builds its own pass-through SCSI device files using the sctl driver, so that driver must be installed; however, L&TT does not need the operating system to list any of the devices as "CLAIMED.
Installing L&TT for HP VMS HP VMS installation prerequisites Software dependencies/prerequisites L&TT requires the following patches or higher to run successfully: • V7.3–2 Alpha VMS732_FIBRE_SCSI-V0800VMS732_UPDATE-V0500 • V8.2 Alpha VMS82A_FIBRE_SCSI-V0100 VMS82A_UPDATE-V0200 • V8.
3. Download or copy the L&TT tar file, hp_ltt.tar (where is the version number) to this directory. If you are copying the file from a different directory, enter the following command, substituting the directory in which the file currently resides for : cp //hp_ltt.tar /tmp 4. Un-tar the L&TT tar file: tar –xvf hp_ltt.tar 5. Run the installation script in the /tmp directory: ./install_hpltt 6.
Starting L&TT To start L&TT: • For HP-UX (pre-11i v3), Tru64, and Linux: Log on as root and execute the following commands: cd /opt/ltt ./hp_ltt • For HP-UX 11i v3: HP-UX 11i v3 provides a new agile addressing format, which can be seen by executing ioscan -fN and supports both persistent (new) and legacy Device Special Files (DSFs). Start L&TT with the -N option to use the new agile addressing format.
Figure 20 Command Help screen Using the scan mode selection screen When the CSI version of L&TT is started, the Scan Mode Selection screen is displayed, as shown in Figure 21 (page 43).
When L&TT starts, it performs a device scan to identify all the devices connected to the computer, either directly or through a SAN. In large SAN environments, this scan can take a long time. The first time L&TT is run, it must perform a full hardware scan (Hardware Scan option). After that is done, the results of the scan are automatically saved so that the next time L&TT is started, the Saved/Manual Scan option can be used.
Figure 23 CSI Main screen Using the device information screen When you first select a product from the Main screen, the device information screen appears, showing information relevant to the device. The main purpose of the device information screen is to provide an overview of the configuration and status of the selected hardware device.
Figure 24 Device information screen for a standalone device Library and autoloader products From the device information screen for a library device, use the cartridge command to display the slot inventory of the library. The cartridge command shows which slots and drives currently have cartridges loaded, and the cartridge bar code if available and applicable.
NOTE: Selecting individual drives within a library from the device list displays the drive as though it were a standalone product. Embedded drives are best diagnosed by selecting the library they belong to, and then selecting the specific drive within each tool window.

Output of the scan is written to the saved_scan.txt file in the L&TT root directory. Examine this file to determine the proper format. This parameter is required. directory Optional. Specify the directory name if you want to override the default location in which L&TT saves the report or support ticket.
Converting a support ticket to XML (CLF) Description L&TT can be run from the command line to convert a support ticket to XML format. For more information about using reports and support tickets, see Reports and support tickets (page 115). The converted support ticket is the same as if it was originally created in XML format.
Return values When an operation is performed from the command line, L&TT returns a value indicating success or failure. Depending on the operation performed, the value returned has different meanings. When L&TT is run from a script, a return value greater than 0 indicates an error condition.
5 Tests L&TT provides numerous tests for analyzing storage hardware. These tests are grouped into two categories: Diagnostic tests and Performance tests. The performance tests are built into the program, but several of the diagnostic tests are SCSI script-based. A SCSI script is a sequence of SCSI commands sent to a device, usually for the purpose of testing the device's functionality.
Drive Specific tests • “Drive Assessment test” (page 72) • “Device Analysis test” (page 73) Drive Assessment test Table 1 Drive Assessment test details Details/Device specific test Drive Assessment test Description The LTO drive assessment test is the most important test in the L&TT diagnostics suite. The test is used to assess the health of a tape drive, providing a clear pass or fail result in about 15 minutes and determines if the drive or autoloader is Fit for Purpose (FFP).
Table 1 Drive Assessment test details (continued) Details/Device specific test Drive Assessment test • Run error rate tests—The test runs a series of internal error rate tests at different speeds and different tape directions. This the core of the assessment test. • Clean up—The error rate tests leave the cartridge in an 'invalid' state, which is reset with a short erase process. Test performed Requires that a cartridge be already loaded or in the process of loading when the test is started.
Table 2 Device Analysis test details (continued) Details/Device specific test Device Analysis test for any known issues, customer use issues, and common error patterns. The test also provides summary information and presents suggestions as to the cause of certain errors and any remedial actions to be taken by the user . This option is particularly useful if you suspect a problem with the device.
Table 3 Media Analysis test details (continued) Details/Media specific test Media Analysis test NOTE: The Media Analysis test reads data from the media and calculates the error rate. If the error rate exceeds the maximum allowable threshold, the test will require a cleaning cartridge and a second tape to determine if the problem is with the drive or the tape. Test is non-destructive and will not overwrite any data on the media.
Table 4 LTO Media Assessment Full Tape test details (continued) Details/Media specific test LTO Media Assessment Full Tape test Options HP recommends using the default options, which will perform a Read Only (Backup Assessment) test and attempt to read two wraps of data from the tape. Use the Allow Overwrite and Amount of Media to Test options to modify the default behavior of the test.
Table 5 Media Validation test details (continued) Details/Media specific test Media Validation test of the media are not changed in any way. Supports several test options for MO and UDO media (data limit options, starting block, block size, failure threshold, and so on), but none for tape. The test also runs a self test and cleaning check, and prompts for cleaning cartridge if it deems necessary (tape only).
LTO Media Assessment test Table 8 LTO Media Assessment test Details/Media specific test LTO Media Assessment test Description This test checks the functionality of your LTO Data Cartridge and ensures that it is working correctly. Load the required cartridge before starting the test. Before running this test, ensure that the drives operation is checked using the LTO Drive Assessment Test (the test must be passed recently with sufficient margin for the results of this test to be valid).

The default setting is on.
Table 11 Library Read Write test details (continued) Details/Library specific test Library Read Write test Options • Allow overwrite (default: FALSE) — Set to TRUE to enable test options which write to the tape. Specifically, if MB to write is greater than 0 or Run LTO drive assessment test is TRUE, the test will only run if Allow overwrite is also true. • Starting slot (defaults to 1) — Specifies the number of the slot where the test will start checking for compatible tapes.
Table 11 Library Read Write test details (continued) Details/Library specific test Library Read Write test sequence will be repeated for each tape/drive combination. • Ignore barcode labels (default: FALSE) — Specifies whether the test should use barcode labels to determine which tapes are compatible with a tape drive. • Skip previously inventoried tapes (default FALSE) — Specifies whether previously inventoried tapes will be skipped when the test selects the tapes to use for the test run.
Table 11 Library Read Write test details (continued) Details/Library specific test Library Read Write test configuration of tape locations. If the Library Read Write test is run after a tape is removed from the library, the information about that tape is discarded from the log file. TIP: To keep log information about a tape that has been discarded from the library, copy or rename the log file before running the Library Read Write test.

6 Reports and support tickets A prime feature of L&TT is the ability to generate reports and support tickets. In the event of a hardware problem, a report or support ticket can provide vital information to help diagnose and resolve the problem. Reports and support tickets can be generated on all operating systems supported by L&TT. Much of the information stored within a device related to operational characteristics is used by various L&TT tests to analyze the health of the device.
is set to the desired level before generating the HTML report because the detail level within the HTML file cannot be changed. • When generating a report or support ticket for standalone devices, HP recommends that you keep the media in the drive in which it was present when the failure occurred. This allows error rate and other information relevant to that cartridge to be examined. When media is removed, many devices automatically clear this information.
• The system information – if the ticket was pulled using L&TT, but not if generated from Command View TL. • The library • The drives The decode is arranged hierarchically in the above order and is easy to navigate. To reduce the load time for large library tickets, the sub-ticket data is not pulled in from the ticket file until the device is clicked in the viewer. When pulling tickets from a library, select the library first and then pull the ticket.
Figure 43 Support ticket System Configuration section When troubleshooting, check for: • Tool version—The version of L&TT from where the ticket was extracted. The raw data does not change over time, but HP recommends using the latest version of L&TT for both extracting and viewing tickets. • Active services such as Windows RSM or the Insight Management agents. • Old driver revisions—The most current drivers must be used.
In most cases additional categories between Drive and Interface cleanly separate drive issues from interface issues, which can have similar symptoms and make it difficult to find the cause of a symptom. L&TT assesses the values reported by the drive and expresses them, when appropriate, as margin: • Great – The value is about as good as it can be. No action is required. • Good – The value is not as good as represented by Great but still has sufficient margin. No action is required.
Understanding STTF support ticket Tape drive creates a snapshot log in volatile memory and saves it to an area of non-volatile memory (flash). To generate STTF log, configure the trigger conditions. The STTF Configuration list contains the descriptors that define the configurable STTF trigger conditions for creating a snapshot log and the Command Set used to create the log. Snapshot logs are stored in a single area of contiguous memory.

7 Additional functionality This chapter describes additional features of the program that are not covered elsewhere in this guide.
Figure 48 L&TT Preferences dialog box (default settings shown) To set the preferences in the CSI version of L&TT from the Main screen, use the preferences command to display the Preferences screen.
Figure 49 L&TT preferences dialog box (CSI version) Available options The following list describes the available options. Some options are not available with CSI versions of L&TT. • Firmware Files or Firmware file path — The location where L&TT stores and accesses firmware files on your local system. When using the “Get Firmware From Web” feature, firmware files are automatically downloaded to this directory.
• Enter Maximum emailsize— This option lets you specify a maximum size (in megabytes) for support tickets. If the support ticket exceeds this size, it will be broken up into smaller subtickets. • Check for updates on web — This option is only available for Windows, Linux, and HP-UX. When this option is enabled, L&TT uses an available Internet connection to look for product updates, such as firmware upgrades, new device analysis rules, and new version of L&TT.
Using the Internet update functionality The Windows, Linux, and HP-UX versions of L&TT can automatically notify the user of the following conditions each time the program is started: • A new version of L&TT has been released • A new version of firmware is available for a connected storage device • A new version of device analysis rules is available for a connected storage device This notification only occurs if the user has the Check for updates on web option enabled in the preferences dialog (this op

If this system is not connected to the Internet, use the Selected Item URL to access the advisory from another system.
Using passwords A number of tool features are available only when enabled with a password. The password is intended to prevent inexperienced users from accessing functionality that may be particularly harmful to their system if used improperly. These features include: • Firmware Downgrade lets you downgrade firmware revisions. The device product ID and revision string sequence must match.
Figure 51 Front panel Using the Move Media function Most supported libraries and autoloaders support a set of commands for moving media from one location to another within the device. Whenever possible, L&TT takes advantage of this functionality to provide a convenient way to move media within a library or autoloader. This functionality is supported in both the GUI and CSI versions of L&TT. With the Windows version of L&TT, the Move Media functionality is incorporated into the Front Panel screen.
Figure 52 Move Media screen The Move Media screen is divided into two sections showing all available source and destination drives, slots, and mailslots. To move media from one location to another, selected the desired source and destination locations and click Perform Move. NOTE: Only one item can be moved at a time, so it is not possible to select multiple source or destination locations. The Perform Move button is grayed out until a valid source and destination have been selected.

9 Accessing HP library LTO-5 and LTO-6 drives over Ethernet HP LTO-5 and LTO-6 library tape drives support drive diagnostics via the Ethernet interface using the Internet Diagnostics Tool Interface (iDTI) protocol. L&TT 4.14 and newer releases now support this feature with the Ethernet mode. With Ethernet mode, you can perform most diagnostics from a laptop (with L&TT installed) that is connected to the drive or library with an Ethernet cable.
Figure 63 Ethernet ports on switch in the ESL-e and EML-e libraries For the ESL G3 library, connect to the service port, as shown in Figure 64 (page 145). Figure 64 ESL G3 service port For the 1/8 G2 Tape Autoloader and MSL2024, MSL4048, MSL6480, MSL8048, and MSL8096 tape libraries, connect to the Ethernet port on the tape drive, as shown in Figure 65 (page 146).
Figure 65 Ethernet port on LTO-5 tape drive in the 1/8 G2 Tape Autoloader and MSL libraries NOTE: The 1/8 G2 Tape Autoloader and MSL libraries also have an Ethernet port, which is used for the remote management interface. L&TT does not use this port, L&TT uses the port on the tape drive. When the laptop is connected to the proper port, the library controller dynamically assigns an IP address to the laptop. The laptop's Ethernet adapter must be set to acquire an IP automatically.
10 Frequently asked questions This chapter addresses several of the most common questions regarding L&TT software.
Why should I use latest version of LTT? The latest version generally have some new features and defect fixes. It is always recommended to use latest version supported for any OS platforms. How do I get to know the latest version of LTT? When you run LTT, there is pop up message about the new releases.
Where can I find information about hardware and software compatibility? The links in this section provide information about hardware and software compatibility. NOTE: You must be connected to the Internet to view these links.
How do I use L&TT to find my drive serial number? • With the Windows version, select the device and click Identity on the toolbar. The device information screen displays the serial number. • With the CSI version, from the Main screen, enter select , where n is the number of the device. The device information screen displays the serial number.
How do I send a support ticket? • Use the email support ticket option if possible. See ???. • If the above option is not possible, save the ticket to a single directory. Then archive the files into a compressed archive and attach the archive file to an email. NOTE: Customer support personnel typically provide an email address to users who are emailing a support ticket as a result of a support call request. In this case, the user should enter the email address exactly as provided by the support person.
• “How do I send an L&TT event log?” (page 152) • “If backup/restore fails what I should do?” (page 152) • “How LTT can help to identify the problems during backup/restore?” (page 152) Was my backup successful (LTO only)? To determine whether a backup to LTO tape was successful: 1. Perform the backup as you normally would. 2. Generate a support ticket for the drive to which the backup was performed. 3. Locate the Loaded Tape > Cartridge Health section of the support ticket and examine the margins.
• “How do I verify the capacity of a tape?” (page 153) • “How many more uses are left in this cleaning cartridge (LTO only)?” (page 153) • “How do I send an L&TT event log?” (page 153) Is my LTO tape OK? To determine if an LTO tape is OK: 1. Load the tape into an appropriate drive of known good health. 2. Generate a support ticket for that drive. 3. Locate the Loaded Tape > Cartridge Health section of the support ticket and examine the margins.
in the logs directory. Archive the file into a compressed archive and attach the archive file to an email. NOTE: Customer support personnel typically provide an email address to users who are emailing a support ticket as a result of a support call request. In this case, the user should enter the email address exactly as provided by the support person. In the European region this will usually be provided in the form: @cases.brussels.hp.com where xxx is the actual assigned case number.
1. 2. 3. 4. Press Ctrl+Alt+Del. Click Task Manager. Click the Processes tab. Select the process named HP_LTT.exe and click End Process. When installing L&TT for Windows, should I uninstall my previous version first? The L&TT installer automatically uninstalls any previous versions before installing the current version, so it is not necessary to manually uninstall your previous version. How do I erase an LTO FUP tape? Run the LTO Firmware to Data Tape Creator test.
You can access the L&TT firmware FTP site at: “ftp.hp.com/pub/information_storage/software/ltt/firmware”. The firmware files are named using the following convention: LTT__.frm For example: LTT_A5617A_0200.frm L&TT starts in restricted mode and most functionality is unavailable. What is happening? L&TT automatically runs in restricted mode when it recognizes a supported device that has a problem with firmware and requires a firmware upgrade.
• Why does L&TT for OpenVMS not see my media changer? • Why am I getting Error activating image PTHREAD$RTL while running L&TT on Open VMS 7.3-1? How do I set the password? With a few exceptions, you may enter the options command at any time to display the Options dialog. The password may be set from this dialog. Exceptions: • You may not enter the Options dialog when you are already in the Options dialog.
Why doesn't L&TT for HP-UX see all the devices connected to a SAN environment? L&TT may not be able to see all of the devices (e.g. libraries) in a SAN environment if the number of files ed by it has reached the maximum limit (maxfiles). Hence, in a large SAN, with a large number of devices and disks, HP recommends setting maxfiles larger than 2048 , depending on the SAN size. Use the commands kmtune or kctune to configure maxfiles.
Why doesn't L&TT for Windows see devices that are connected to a computer running HP-UX? L&TT does not support a client-server model such as the HP-UX Support Tools Manager. You cannot use L&TT on a Windows workstation to view devices that are connected to a computer running HP-UX.
11 Troubleshooting This chapter is divided into the following sections: • Troubleshooting L&TT • Troubleshooting devices • Troubleshooting third-party software Troubleshooting L&TT If you believe that you have encountered a software issue with the L&TT program itself, send an email to LTT.team@hp.com. Please be sure, as much as possible, that it is an L&TT issue rather than a product issue. When sending the email, include the following: • • • A description of the issue ◦ What was being done.
This section starts with the most common questions you may have concerning the health of your tape drive. You can work through each of them in turn or pick one that is most appropriate to your problem. Additional pointers are provided if the problem is not found to be with your tape drive. This section currently only covers standalone drives.
Is the drive working as expected? If you suspect that your drive is not working properly, run the Assessment test for your drive. If the drive passes the Assessment test, then it is considered to be working well with the tape you provided. If the drive fails the Assessment test, the problem might be caused by: • Poor media. Run the test again with a different tape. • Dirty heads. Use a cleaning tape. If the drive still fails after trying both of the above then the issue is most likely with the drive.
Additional interactive device troubleshooting content HP Guided Troubleshooting, also known as FireFly, is an interactive, web-based, guided troubleshooting and reporting utility for an increasing number of HP product including HP tape devices. Use FireFly whenever possible to troubleshoot problems with tape based devices. It contains logically-oriented issue paths to guide you through the troubleshooting exercise in an orderly fashion by listing the most probable causes first in the issue path flow.

C Using a firmware update (FUP) tape The preferred method for updating drive firmware is by using the L&TT application. Firmware can be updated on both Windows and non-Windows platforms. However, there are some cases where L&TT is not available, or otherwise cannot be used (for example, with an unsupported operating system). In these cases, a firmware update (FUP) tape can be created and used for the purpose of updating drive firmware.
Libraries and autoloaders Use of FUP tapes in STK libraries works just as it does for standalone drives. See the description above for that information. For HP libraries: 1. Ensure the target drive is empty. If a tape is in the target drive, use the front panel display to return the tape to a storage slot. 2. Load the FUP tape into an empty slot. 3. From the main menu on the front panel, choose Administration, and then Upgrade Firmware to access the Upgrade Drive Firmware menu. 4.
4. 5. 6. Use the [-] or [+] key to select the slot containing the FUP tape. Select [OK]. Monitor the front panel for status during the upgrade. The tape will return to the original slot when the procedure is complete. Remove the FUP tape from the library, and then power cycle the library. DLT 4000/7000/8000 Standalone VS80/DLT1 drives There is no hard-coded limit on the number of times a given DLT 4000/7000/8000 FUP tape can be used to update the firmware in a particular DLT 4000/7000/8000 drive type.
Ultrium Standalone Ultrium drives There is no hard-coded limit on the number of times a given Ultrium FUP tape can be used to update the firmware in a particular Ultrium drive type. To update an Ultrium drive with a FUP tape, insert the tape into the Ultrium drive. It does not matter if the tape is write protected or write enabled. HP Ultrium drives automatically recognize a valid FUP tape when inserted and begin updating the firmware.
DAT72x10 autoloader The FUP tape will update both the autoloader and drive firmware. To create a FUP tape for a DAT72x10 autoloader: 1. Place the drive firmware and autoloader firmware files in the firmware folder. 2. Rename the drive firmware file firmware1.frm. 3. Rename the autoloader firmware file firmware2.frm. 4. In L&TT, select the autoloader (not the drive) and choose the DAT AL Firmware Tape Creator test. To upgrade firmware using the FUP tape: 1. Move the FUP tape to a slot in the autoloader. 2.
D Support ticket fields Drive health The Drive Health section shows the health of the drive from a number of aspects. Figure 66 Support ticket Drive health section 172 • Device Analysis - These are the ‘rules’ which are run against the drive logs and highlight any concerns and recommend actions. L&TT typically tests over 20 rules and 130 subrules, covering everything from firmware version to read/write health to host polling.
When troubleshooting, check for: • Any output from the device analysis rules. This should be the first place to look. • Any highlighted items. Drive configuration The Drive Configuration section shows how the drive was configured at the time the ticket was pulled, along with the interface configuration, depending on the interface type.
Figure 68 Support ticket Drive Environment section When troubleshooting, check for: • The margin assessment, rather than the reported temperature • Over temperature (or under) will be highlighted Drive performance The Drive Performance section shows performance-related measurements for the drive base on the current and up to four previous tapes.
Figure 70 Support ticket Drive Usage section • Tape Pulled – expressed in full volume equivalents (FVEs), which is the equivalent of writing to or reading from a full tape once. A full volume write followed by a read will give two full volume equivalents. • Duty cycle – the average duty cycle over the life of the drive. This value cannot be reset. For more dynamic duty cycle reporting please use TapeAssure. • Native data volume – this is the amount of data after compression read or written to tape.
Cartridge identity The Cartridge Identity section shows information specific to the last cartridge loaded – either currently loaded or ejected. Figure 72 Support ticket Cartridge Identity section Cartridge health The Cartridge Health section shows the health of the current or last loaded tape. Figure 73 Support ticket Cartridge Health section • Data on tape – covers how much extra tape was used to write high quality data to tape.
Figure 74 Support ticket Cartridge Configuration section When troubleshooting, check for: • Write protected. Not an issue if set, but may cause backups to fail. • (EOD) Validity – can also show backup in progress, if the ticket was pulled during a backup (or the cartridge memory didn’t update correctly). This will be highlighted if not set to valid. Cartridge environment The Cartridge Environment section shows the temperature margins for the tape for the recent drives it was loaded in.
Figure 77 Support ticket Cartridge Usage section Cartridge history The Cartridge History section shows anything specific for this tape that was identified from the history logs of the drive. The section is still in development and not fully populated. Classic support ticket The Classic Support Ticket section is the original, basic decode of the support ticket before the above categories were introduced.
