OceanStor 2800 V5 V500R007

This document is applicable to OceanStor 2800 V5. Routine maintenance activities are the most common activities for the storage device, including powering on or off the storage device, managing users, modifying basic parameters of the storage device, and managing hardware components. This document is intended for the system administrators who are responsible for carrying out routine maintenance activities, monitoring the storage device, and rectifying common device faults.

Collecting Information on DeviceManager

Collecting Information on DeviceManager

You can use DeviceManager to collect system data, alarms, and events in the storage system.

Exporting System Data

Periodically export the system data of a storage system and save it in a safe place. This helps you know the operating status of the storage system and prevent the damage to the storage system caused by system faults and unexpected disasters. When a system failure occurs, the exported system data can be used to locate and analyze the failure. The system data to be exported includes running data, system logs, disk logs, storage resource (for V500R007C20 and later), and diagnostic file (for V500R007C30 and later).

Context
  • Running data indicates the real-time running status of a storage system, such as the configuration information of LUN. The running data file is in *.txt format.
  • System logs record the information about the running data, events, and debugging operations on a storage system and can be used for analyzing the running status of the storage system. The system log file is in *.tgz format.
  • DHA runtime logs are disks' daily running logs, including daily disk health statistics, I/O statistics, and disk service life. The DHA runtime log file is in *.tgz format.
    • DHA runtime logs collect S.M.A.R.T/LogPage information (collected at 2 o'clock every morning), I/O statistics (collected every 2 hours), and disk service life (collected at 2 o'clock every morning). A log package (1 KB) is generated for each disk each day. A controller can generate a maximum of 74 log packages for each of the disks belonging to it within a year (some old log packages will be deleted during the collection). In a log package export, packages corresponding to each controller are generated. Each package contains log packages and one basic information file about each disk belonging to the corresponding controller.
      NOTE:

      You can run the change dha policy collect_start_time=? command in developer mode in the CLI to change the collection start time of DHA logs.

    • Recommended times of export during routine maintenance are listed in the following table. The analysis of DHA logs is only performed on samples instead of all logs. To prevent the analysis of DHA logs from affecting the entire routine maintenance, take the recommended values only for reference.

  • HSSD log is working log of HSSD, such as the S.M.A.R.T information and run logs of the disk. The HSSD log file is in *.tgz format.

    Before the download of system logs, DHA runtime logs, or HSSD logs, the system collects those logs of controllers and shows the collection progress. After all logs are collected, you can download your desired logs.

    After the system starts collecting system logs, DHA run logs, or HSSD logs, you need to wait for five minutes or download all the collected logs before you collect and download other logs.

  • In the storage resource file, you can easily view information about resources, including storage pools, LUNs, file systems, Qtrees, and quotas.
  • Diagnostic files collect the device faults. The diagnostic files are in *.tgz format.
Procedure
  1. Log in to DeviceManager.
  2. Choose Settings > Export Data.
  3. Export data.

    • In the Running Data area, click Download. Confirm the information in the security alert dialog box, select I have read and understand the consequences associated with performing this operation, and click OK.

      The system running data is exported.

    • In the System Log area, select Recent logs or All logs, and click Log List. Confirm the information in the security alert dialog box, select I have read and understand the consequences associated with performing this operation, and click OK.

      The system starts collecting logs and expands the log list.

    • In the Disk Log area, click DHA Runtime Log List. Confirm the information in the security alert dialog box, select I have read and understand the consequences associated with performing this operation, and click OK.

      The system starts collecting logs and expands the log list.

    • In the Disk Log area, click HSSD Log List. Confirm the information in the security alert dialog box, select I have read and understand the consequences associated with performing this operation, and click OK.

      The system starts collecting logs and expands the log list.

    • For V500R007C20 and later, in Storage Resource area, click Export Storage Resource. Confirm the information in the security alert dialog box, select I have read and understand the consequences associated with performing this operation, and click OK.

      The storage resource configuration file is exported.

    • For V500R007C30 and later, in Diagnostic File area, click Export. Confirm the information in the security alert dialog box, select I have read and understand the consequences associated with performing this operation, and click OK.

      The device faults information is exported.

    NOTE:
    • In the System Log area, if Recent logs is selected, the system exports recent logs that have been generated by the current point in time. The logs include the latest one power-on and power-off log and a maximum of six messages logs. If All logs is selected, the system exports all logs on the current node. Note that historical messages logs are saved to the /OSM/coffer_log/log/his_debug directory.
    • If you export the data using the Internet Explorer browser with the default settings, the data will be saved in the download path which the user has selected. For example, you can choose Save > Save as in the displayed file download dialog box and select the download path in Internet Explorer 9 browser.
    • If you export the data using the Firefox browser with the default settings, the data will be saved in the default download path of the browser. You can choose Tools > Options and click the General > Browser in the Options dialog box to view the default download path.
    • If you export the data using the Google Chrome browser with the default settings, the data will be saved in the default download path of the browser. You can choose Customize and Control Google Chrome > Settings and view the default download path in the Download Content area of the Settings page.
    • When using Chrome to export for the first time, click Allow if the This site is attempting to download multiple files. Do you want to allow this message? message is displayed. Otherwise, at the upper right corner of the browser, choose Customize and control Google Chrome > Settings > Privacy and security > Content Settings... > Automatic downloads > Manage exceptions, select Allow in Behaviour, and click Finished. Then, reopen the web page and you can successfully download multiple files. Alternatively, delete Block from Behaviour and click Finished. Then, reopen the web page again and you can download multiple files. In such a case, a message asking whether to allow multiple files to be downloaded will be displayed.
    • If the exported logs cannot be viewed, export the logs again. If the new logs still cannot be viewed, contact Huawei technical support.
