Make sure that the management server on which you plan to install Hitachi Ops Center products meets the system requirements.

For the Common Services system requirements, see the Hitachi Ops Center Release Notes. For the system requirements of other Hitachi Ops Center products, see the documentation or Release Notes for each product.

For a complete list of Hitachi Ops Center system requirements, go to the Ops Center documentation site and select Hitachi Ops Center System Requirements.

Note:
  • Hitachi Ops Center does not support installing other software products on the management server, but allows for installing software required by corporate policy such as anti-virus programs and third-party monitoring agents. Note that Hitachi Vantara does not take responsibility for or support any interactions between the third-party programs and the Hitachi Ops Center software.
  • When Common Services is installed, the following RPM packages are installed:
    • Amazon Corretto 21
    • PostgreSQL 15
  • Common Services starts the Common Services service by using the postgres user and postgres group created on the management server.

    Configurations where postgres users and postgres groups do not exist on the management server are not supported.

    If the users on the management server are managed by an external authentication server, the Common Services service cannot start when the OS starts.

Make sure that you complete the following actions on the installation destination management server:

  • To install prerequisite packages, the Server Express installer requires the repository settings for the yum command. Specify the yum repository settings in advance, or specify the settings by following the message displayed when you run the Server Express installer.
  • Administrator requires Podman as a container runtime.

    For Podman-related software (podman, containers-common, conmon, runc), make sure that versions supported by Administrator are installed on the management server.

    If they are not installed, install them by using the following methods:
    • Installation by using the Server Express installer

      When you install by using the Server Express installer, the yum command is run during the Administrator installation and the Podman-related software is installed. Configure the yum repository settings in advance or when running the Server Express installer so that a supported version of the Podman-related software can be installed.

    • Installation by using the OS media

      If the yum repository does not contain a supported version of the Podman-related software, install a supported version of the Podman-related software by using the OS media.

    For details on supported versions and how to install them, see the Hitachi Ops Center Administrator Getting Started Guide.

Note: If you run the Server Express installer, the iptables and firewalld settings are changed so that required communications can be established. If you use nftables, you must make the changes manually.
