Upgrading the Analyzer probe server

If you upgrade the Analyzer probe server, the RAID Agent on the same host is automatically upgraded, but Ops Center API Configuration Manager and other Ops Center products are not upgraded.

The installer (dcaprobe_install.sh) starts and stops the crond service. Therefore, do not run any operations that use the crond service when the installer is running.

Before you begin

  • To upgrade the Analytics probe server from a version earlier than 4.0.0, you must first upgrade the Analyzer probe server to version 4.0.0.
  • A license for the Analyzer probe server must be registered.
  • Review the Analyzer probe server requirements (hardware and software).
  • When upgrading from a version earlier than 10.0.0, make sure that both the root directory and the installation directory of the host on which you plan to install the Analyzer probe server has 5 GB of free space.
  • During the upgrade, /opt/jp1pc/htnm/HBasePSB/hjdk/jdk might be deleted. If you have created files under this directory, move them elsewhere. If any settings (such as htnm_httpsd.conf) reference a file under this directory, revise them to use the new location.
Procedure
  1. Log on to the host where the component to upgrade is installed.
  2. Stop any security monitoring software, antivirus software, and process monitoring software.
  3. Mount the Hitachi Ops Center installation media and copy the directories and files in the DCAPROBE directory from the installation media to a directory on the Linux host.
    Note
    • You must use only the following characters in the directory path to which the installer is copied: A-Z a-z 0-9 - . _
    • Do not use spaces.

    In the following example, if the /root/DCAPROBE directory already exists, create a new directory, and then perform the subsequent steps in the new directory.

    mkdir /media/OpsImage
    mount /dev/cdrom /media/OpsImage
    mkdir /root/DCAPROBE
    cp -rT /media/OpsImage/DCAPROBE /root/DCAPROBE
  4. Move to the /root/DCAPROBE directory.
    cd /root/DCAPROBE
  5. Run the precheck tool as a root user to check whether Analyzer probe server can be installed:
    sh ./dcaprobe_precheck.sh

    If OK is displayed in [ Check results ], you can start the installation. If NG is displayed, make sure the system requirements have been met.

    Output example when the Ops Center Analyzer version is 10.0.0:

    ============================================================
     Ops Center Analyzer probe Precheck          ver. 10.0.0-00
    ============================================================
    
    [ Check results ]
    Ops Center Analyzer probe server [10.0.0-00]            [OK]
    
    [ Details ]
    Check resolved hostname. [host-name (IP-address)]       [OK]
    Check premise OS version.                               [OK]

    If the following message is displayed, you must change the JDK used by the Analyzer probe server. For details, see Resolving a JDK-related error for the Analyzer probe server.

    JDK environment is invalid (invalid-settings).
    For invalid-settings, one or more of the following values is displayed: java, keytool, jstack, jre_1.8.0, or java_home.
    Note
    • When you run the precheck tool, it checks the static information of the system environment.
    • If the -v option is specified, information such as the installed version of Analyzer probe server and the OS name is also displayed.
  6. Run the following command as root to start the upgrade:
    sh ./dcaprobe_install.sh VUP
    • Do not change the size of the device window while the command is running. If you change the size of the window, the installation fails.
    • If the following message is displayed, you must change the JDK used by the Analyzer probe server. For details, see Resolving a JDK-related error for the Analyzer probe server.
      [ERR]  JDK environment is invalid (invalid-settings).

      For invalid-settings, one or more of the following values is displayed: java, keytool, jstack, jre_1.8.0, or java_home.
