    2. Disaster recovery issues
      1.  
        Backup data present on the primary site before the time Storage Lifecycle Policies (SLP) was applied is not replicated to the secondary site

      14.  
        When NetBackup Flex Scale is configured, the size of NetBackup logs might exceed the /log partition size
      15.  
        Nodes may go into an irrecoverable state if shut down and reboot operations are performed using IPMI-based commands
      16.  
        Add node fails because of memory fragmentation
      17.  
        Replace node may fail if the new node is not reachable

    Fixed issues

Operations such as add node, replace node, and initial configuration of the cluster fail if the system clocks are not in sync

Adding a node, replacing a node from an existing cluster, and initial configuration of the cluster fails if the system clocks of all the nodes are not synchronized. (IA-31639)

Workaround

Synchronize the system clocks on the all nodes before you begin the cluster configuration or add or replace a node from the cluster.
