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

  • You must have installed Java 11 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, 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 11 on your Linux host.

    If you are using Windows Server 2019 or Windows Server 2016 for the SnapCenter Server host, you must install Java 11. 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. 
    Cmnd_Alias HPPLCMD = sha224:checksum_value== /home/LINUX_USER/.sc_netapp/snapcenter_linux_host_plugin.bin, /opt/NetApp/snapcenter/spl/installation/plugins/uninstall, /opt/NetApp/snapcenter/spl/bin/spl, /opt/NetApp/snapcenter/scc/bin/scc
Cmnd_Alias PRECHECKCMD = sha224:checksum_value== /home/LINUX_USER/.sc_netapp/Linux_Prechecks.sh
Cmnd_Alias CONFIGCHECKCMD = sha224:checksum_value== /opt/NetApp/snapcenter/spl/plugins/scu/scucore/configurationcheck/Config_Check.sh
Cmnd_Alias SCCMD = sha224:checksum_value== /opt/NetApp/snapcenter/spl/bin/sc_command_executor
Cmnd_Alias SCCCMDEXECUTOR =checksum_value== /opt/NetApp/snapcenter/scc/bin/sccCommandExecutor
LINUX_USER ALL=(ALL) NOPASSWD:SETENV: HPPLCMD, PRECHECKCMD, CONFIGCHECKCMD, SCCCMDEXECUTOR, SCCMD
Defaults: LINUX_USER !visiblepw
Defaults: LINUX_USER !requiretty

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

    You can obtain the checksum_value from the sc_unix_plugins_checksum.txt file, which is located at:

    • C:\ProgramData\NetApp\SnapCenter\Package Repository\sc_unix_plugins_checksum.txt if SnapCenter Server is installed on Windows host.

    • /opt/NetApp/snapcenter/SnapManagerWeb/Repository/sc_unix_plugins_checksum.txt if SnapCenter Server in installed on Linux host.

      Important The example should be used only as a reference for creating your own data.
