Use the Dump tool to download dump files onto a management client. The downloaded dump files can be used to:
  • Troubleshoot the system. Use the Dump tool to download dump files from the SVP and give it to the support personnel.
  • Check system configuration. First, click File > Refresh All to update the configuration information, and then use the Dump tool to download the dump files.
  • Back up the software setting information on the SVP before deleting the storage management software and the SVP software.

Types of dump tools:

  • Normal Dump tool (file name: Dump_Normal.bat): Use the Normal Dump tool to obtain the Dump_Normal.bat file. The Dump_Normal.bat file includes all information about the SVP and the minimum information about the storage system. Select this when you have a less serious problem such as incorrect display.
  • Detail Dump tool (file name: Dump_Detail.bat): Use the Detail Dump tool to obtain the Dump_Detail.bat file. The Dump_Detail.bat file includes all information about the storage system in addition to the Normal Dump data. Select this when Device Manager - Storage Navigator has a serious problem (for example, HDvM - SN does not start) or when you need to determine if the storage system has a problem.
  • Initial Analysis Dump tool (file name: Dump_MoreRapid.bat): Use the Initial Analysis Dump tool to obtain the Dump_MoreRapid.bat file. The Dump_MoreRapid.bat file includes the minimum dump data required to perform the initial dump analysis of SSBs and SIMs. Select this when you must start the initial analysis of the problem as soon as possible if a failure occurs. This dump tool is available for SVP firmware version 93-06-21-xx or later.
  • You must be logged in to the SVP.
  • HDvM - SN must be running.
  • The configuration information must be refreshed by selecting File > Refresh All in HDvM - SN.
  • All other users (including the SVP user) must stop using the Dump tool.
  • All maintenance operations must be stopped.
  • Dump tools from other storage systems must not be used during the process.
  • The installation directory of HDvM - SN must be excluded from the real time virus scan targets by the virus detection program.
Note:
  • If the error is in regards to HDvM - SN starting up, collect information about the SVP using the Dump tool, without HDvM - SN running.
  • Even when HDvM - SN is not running, you can use the Dump tool if the status of the storage system displayed in the Storage Device List is Ready. Although you can use the Dump tool when the status of the storage system displayed in the Storage Device List is Warning or Error, the dump data for the DKC and GUMs might not be collected. Check DumpResult.txt shown in step 5 to see whether the dump data for the DKC and GUMs exists.
  1. Close all HDvM - SN sessions on the SVP.
  2. Open a Windows command prompt with administrator permissions.
  3. Move the current directory to the folder where the tool is available. (For example: <SVP-root-directory>\DKC200\mp\pc).
  4. Specify the output destination of the dump file and execute Dump_Detail.bat, Dump_Normal.bat, or Dump_MoreRapid.bat.
    For example, if you are storing the result of Dump_Detail.bat to C:\Result_832000400001, enter the following:
    C:\MAPP\wk\832000400001\DKC200\mp\pc>Dump_Detail.bat C:\Result_832000400001
    Note:
    • A space is required between Dump_Detail.bat and C:\Result.
    • The dump file name is hdcp.tgz. To manage dump files by storage systems, we recommend adding a serial number to the output folder name. For example, if the serial number is 832000400001, the folder name should be C:\Result_832000400001.
    • A folder under the network drive cannot be specified as the output destination.
    • When the tool is being executed, Executing is displayed in the command prompt. When the execution is completed, the following is displayed:
      zSv_AutoDump.exe is completed.

      "zSv_AutoDump.exe is completed." might not be displayed even after the completion of the tool execution due to the heavy load on the SVP or other cause. If it is not displayed even after 20 minutes, check whether a dump file is output in the output folder for the dump file. When a dump file is output, see the date and time of the file update to confirm that the file is created after 20 minutes have passed since the start time of execution of the dump tool. When no dump file is output, close the command prompt and execute the dump tool again.

      Note: If the execution fails, zSv_AutoDump.exe is failed is displayed.
    • You cannot specify the folders under the network drive as the output folder.
    • The dump file capacity might become approximately 3 GB depending on the usage of the storage system.
    • If "zSv_AutoDump.exe is failed." is displayed when you run the dump tool, the installation directory of HDvM - SN might not be excluded from the real-time virus scan target in the virus detection program. Exclude the installation directory from the virus scan target.
  5. A completion message box displays. Press any key to acknowledge the message and close the message box.
    hdcp.tgz: This is the dump file. Give this file to the maintenance personnel. If you save too many dump files in the SVP storage, space might not be available. Therefore, move the dump file outside of SVP storage.

    zSv_AutoDump.log: This is the log file of the dump tool. If the dump file is not output, give this log file to the maintenance personnel. If the dump file is output, delete the log file.

    DumpResult.txt: This is the collection results file. The results are displayed in the following catagories:

    DKC dump
    Collection result of the DKC dump data
    Dump of GUM of CTRL1
    Collection result of the GUM (CTL1) dump data
    Dump of GUM of CTRL2
    Collection result of the GUM (CTL2) dump data

    exist is displayed if the collection was successful. not exist is displayed if the collection has failed.

  6. Close the Windows command prompt.
