Installation Requirements

The very first step in this process is to determine if you have a Dell PowerVault LTO tape drive as referenced as an IBM LTO or an IBM Ultrium tape drive.

The type of Dell PowerVault LTO tape drives are as follows:

  • IBM LTO2
  • IBM LTO3
  • IBM LTO4
  • IBM LTO5
  • IBM LTO6

These could be full height or half-height tape drives, single tape drives, or in a tape library.


Download the firmware for the type of Dell PowerVault Tape Drive you have from Dell's Support site.  The ITDT-DCR (IBM® Total Diagnostic Tool - Dell Customer Release) should be included in the firmware.

If you are not able to find ITDT within the extracted firmware download for your tape drive, you can use ITDT-DCR from the PowerVault TL2000 / TL4000 Tape Library firmware download.

 

Note: the (gcj-based) JRE originally delivered with Red Hat Enterprise Linux 4 and Red Hat Enterprise 5 (RHEL) is not supported. So please install one of the supported JRE's before launching the ITDT-DCR installation application.

 

It is strongly recommended to not operate Security Enhanced Linux (SELinux) in enforcing mode while running ITDT-DCR.

On RHEL and other Linux systems where the Supported JREs are not part of the search path, the PATH environment variable has to be adjusted to include the directory where the binaries for the Supported JRE is located before starting the installer. Examples:
 

IBM JRE:
$ export PATH=/opt/IBMJava2-142/jre/bin:$PATH
$ ./install_ITDT_DCR_<version>.bin

Sun Microsystems JRE:
$ export PATH=/usr/java/j2re1.4.2_17/bin:$PATH
$ ./install_ITDT_DCR_<version>.bin

In such a case, after the installation a symbolic link has to be created to ensure that the installed ITDT-DCR will find the JRE. Examples:
 

IBM JRE:
$ ln -sf /opt/IBMJava2-142/jre /opt/dell/itdt-dcr/jre

Sun Microsystems JRE:
$ ln -sf /usr/java/j2re1.4.2_17 /opt/dell/itdt-dcr/jre
 

Adjust the paths used above to match the location of the JRE version you are using. If you decided to install the ITDT-DCR into another directory, adjust the ITDT-DCR directory in the examples above when issuing the commands.

For the graphical user interface a minimum screen resolution of 1024*768 pixels is required.

If you cannot have Java on your server, consider downloading ITDT-SE (Standard Edition) from the IBM site.

 



Installation Steps

 

The following ITDT_DCR installation comes from the PowerVault TL2000 / TL4000 Tape Library firmware (as an example):

  1. Download the firmware from Dell's Support Site.
  2. Extract the firmware to a location (or directory), where you can find it, if necessary.
    The download could be downloaded on a Windows® or a Linux® system.
    If downloaded on a Windows system, the download will need to be copied or moved to the Linux® system using WinSCP for example.
  3. After the firmware has been extracted, the directory should open as a window, as seen below.

    SLN156837_en_US__11375136906925.Figure-1_ITDT-DCR_Extraction

    SLN156837_en_US__21375136968832.Figure-2_ITDT-DCR_Extract_Locaation

    In this example, the firmware file was extracted on a Windows® server.
  4. Go into the ITDT-DCR installation folder.

    SLN156837_en_US__31375137026739.Figure-4_ITDT-DCR_Directory
  5. Use the Readme_itdt_dcr file to read about the requirement, installation, etc., of ITDT-DCR is recommended.
  6. Open a command-line window on the Linux® after the install_ITDT_DCR_4.0.0.021.bin has been tranferred or copied to the Linux® server.
  7. The file, install_ITDT_DCR_4.0.0.021.bin, has been put in the \tmp directory.

    SLN156837_en_US__41375137398494.Figure-1_ITDT-DCR_Linux_Directory
  8. If you type, "./install_ITDT_DCR_<file version>.bin -help", you will get a listing of the options available.

    In this situation, we typed in "./install_ITDT_DCR_4.0.0.021.bin -help", you will get the following below:

    SLN156837_en_US__51375137350306.Figure-2_ITDT-DCR_Linux_Help_Switch
  9. To install ITDT-DCR for Linux, type the following:

    SLN156837_en_US__61375210514441.Figure-3_ITDT-DCR_Linux_Install_GUI
  10. If you get a warning about not having Java® installed, you will need to install it by going to one of the following links:
    1. Oracle
    2. IBM
  11. Once the minimum version of Java is installed (if not already installed), you should be able to install ITDT-DCR.
  12. The following shows the installation process:

Tape Drive Diagnostics

 

The following process is how to use ITDT-DCR to perform tape drive diagnostics on an PowerVault / IBM LTO Tape Drive:

  1. Before scanning for LTO-like devices, make sure the backup software service(s) are stopped.

    SLN156837_en_US__181375201656021.Figure-15_ITDT-DCR_Scan

    If necessary, stop and disable the services within the Windows® Services window, and restart the server.
  2. Use the Scan button to scan the server for LTO-like devices.
  3. If a message about "Please stop all backup jobs" come up, please answer appropriately.

    SLN156837_en_US__191375201732335.Figure-16_ITDT-DCR_Stop_Backups 

    If necessary, stop all backup jobs within your backup application. Then, stop the backup software services.
  4. When done scanning, ITDT-DCR should return results like the following below:

    SLN156837_en_US__201375201828008.Figure-17_ITDT-DCR_Scan_Complete
  5. Select the tape drive that you would like to use the tape diagnostics on.

    SLN156837_en_US__211375201978449.Figure-18_ITDT-DCR_Drive_Selected
  6. Select the best diagnostics test that suits your situation. 

    SLN156837_en_US__221375202045091.Figure-19_ITDT-DCR_Test

    In most cases, ITDT Standard Test, is the recommended diagnostic test to use.
  7. If you have a tape library (or something similar), it might require a tape to be put in the I/O Slot.

    SLN156837_en_US__231375202168999.Figure-20_ITDT-DCR_IO_Station

    If it is a single tape drive, please put an over-writable or new tape into the tape drive.
  8. The following will show the different parts of the ITDT Standard Test for a LTO-6 tape drive:

    SLN156837_en_US__251375202365534.Figure-22_ITDT-DCR_Load_Unload

    SLN156837_en_US__271375202788199.Figure-23_ITDT-DCR_Post_A

    SLN156837_en_US__281375202840778.Figure-25_ITDT-DCR_Performance

    SLN156837_en_US__291375202937373.Figure-25_ITDT-DCR_Post_B

    SLN156837_en_US__301375203018109.Figure-27_ITDT-DCR_Test_Passed
  9. At the end of the diagnostics, ITDT-DCR will show either passed or failed.

    If it did fail, consider testing with another tape (preferably new), and run ITDT_DCR again.

 


 

Tape Drive Logs (Dump)

 

If a tape drive fails the ITDT-DCR's Standard Test, consider gathering the Tape Drive Log (or drive dumps) for the suspect tape drive.

By gathering the tape drive dumps, it can help to expedite the process to determine if the tape drive needs to be replaced.

 

Note : If you gather the tape drive dumps, please contact Dell Technical Support with the tape drive dumps for further assistance and diagnosis.

 

The following describes the tape drive log gathering process:

  1. Select the tape drive that you want to gather the tape drive dumps for.

    SLN156837_en_US__311375203540338.Figure-29_ITDT-DCR_Log_Drive_Selection
  2. In this case, select Info > Get Log Files

    SLN156837_en_US__321375203590855.Figure-30_ITDT-DCR_Get_Log_Files
  3. A message might come up that says "Do you want to retrieve Cartridge Memory data?"

    SLN156837_en_US__331375203654293.Figure-31_ITDT-DCR_Load_Cartridge

    This might come in useful if more expert attention is needed to determine if media or the tape drive is the root cause of the issue.

    Generally, you will want to select "No", unless otherwise told that it is needed.
  4. Now ITDT-DCR should begin to retrieve the tape drive dump, as seen below:

    SLN156837_en_US__341375204104083.Figure-32_ITDT-DCR_Drive_Dump
  5. The logs can be retrieved in the following location:
