NetWorker 19.7 Snapshot Management Integration Guide

Configuring a cluster environment for snapshots

The recommended cluster configuration includes the NetWorker server and the storage node on separate hosts outside of the cluster.

1. In a local directory, install NetWorker client software on each physical node of the cluster.

   The NetWorker Cluster Integration Guide provides details.

2. Although the snapshots are created on the virtual node, each physical node in the cluster must be a cluster-aware NetWorker client. On each physical node run the cluster configuration script:
   • Microsoft Windows:

     NetWorker_install_path\lc_config

   • UNIX:

     /NetWorker_install_path/networker.cluster

     The NetWorker Cluster Integration Guide provides details.

3. For each virtual node in the cluster that requires NetWorker snapshot services, configure a NetWorker Client resource. Include the following settings:
   1. In the Application Information attribute, specify the shared directory path in the NSR_PS_SHARED_DIR variable.

      NetWorker creates the ssres file in this directory. The ssres file contains transaction logs that NetWorker uses to clean up aborted snapshots and return the snapshot environment to the pre-snapshot state.

      This shared directory can be at one of the following locations:

      • Storage that the application resource group manages.
      • A global file system that is accessible to all the cluster nodes.

        Common Application Information variables provides details.

   2. In the Remote Access attribute, specify the system (Windows) or root (UNIX) account and the hostname or cluster IP of each physical node within the cluster. For example:
      • Microsoft Windows:

        system@clus_phys1
        system@clus_phys2

      • UNIX:

        root@clus_phys1
        root@clus_phys2
