Prerequisites for adding hosts and installing SnapCenter Custom Plug-ins

Before you add a host and install the plug-ins packages, you must complete all the requirements. The Custom Plug-ins can be used in both Windows and Linux environments.

  • You must have created a custom plug-in. For details, see the developer information.

    Develop a plug-in for your application

  • If you want to manage MySQL or DB2 applications, you must have downloaded the MySQL and DB2 Custom Plug-ins that are provided by NetApp.

  • You must have installed Java 1.8 or Java 11 (64-bit) on your Linux or Windows host.

  • When installing a plug-in on a Windows host, if you specify a credential that is not built-in, or if the user belongs to a local workgroup user, you must disable UAC on the host.

  • The Custom Plug-ins must be available on the client host from where the add host operation is performed.

General

If you are using iSCSI, the iSCSI service should be running.

SHA512 hash

  • For custom plug-ins provided by NetApp, you should ensure that you have added the SHA512 hash of the custom plug-in file to the custom_plugin_checksum_list file.

    • For Linux host, the SHA512 hash is located at /var/opt/snapcenter/scc/custom_plugin_checksum_list.txt

    • For Windows host, the SHA512 hash is located at C:\Program Files\NetApp\SnapCenter Plug-in Creator\etc\custom_plugin_checksum_list.txt

      For custom installation path, the SHA512 hash is located at <custom path>\NetApp\SnapCenter\Snapcenter Plug-in Creator\etc\custom_plugin_checksum_list.txt

    The custom_plugin_checksum_list is part of the custom plug-in installation on the host by SnapCenter.

  • For custom plug-ins created for your application, you should have performed the following steps:

    1. Generated the SHA512 hash of the plug-in zip file.

      You can use online tools like SHA512 hash.

    2. Added the generated SHA512 hash to the custom_plugin_checksum_list file in a new line.

      The comments start with # symbol to identify the plug-in to which the hash belongs.

      Following is an example of an entry of SHA512 hash in the checksum file:

Windows hosts

  • You must have a domain user with local administrator privileges with local login permissions on the remote host.

  • If you manage cluster nodes in SnapCenter, you must have a user with administrative privileges to all the nodes in the cluster.

Linux hosts

  • You must have enabled the password-based SSH connection for the root or non-root user.

  • You must have installed Java 1.8 or Java 11 (64-bit), on your Linux host.

    If you are using Windows Server 2019 or Windows Server 2016 for the SnapCenter Server host, you must install Java 1.8 or Java 11 (64-bit). The Interoperability Matrix Tool (IMT) contains the latest information about requirements.

  • You must configure sudo privileges for the non-root user to provide access to several paths. Add the following lines to the /etc/sudoers file by using the visudo Linux utility.

    Note Ensure that you are using Sudo version 1.8.7 or later.

    LINUX_USER is the name of the non-root user that you created.

    You can obtain the checksum_value from the oracle_checksum.txt file, which is located at C:\ProgramData\NetApp\SnapCenter\Package Repository.
