          Continuous replication fails when the 'had' daemon is restarted on the target manually
        12.  
          Continuous replication is unable to come in replicating state if the Storage Replicated Log becomes full
        13.  
          Unplanned failover and failback in continuous replication may fail if the communication of the IPTABLE rules between the cluster nodes does not happen correctly
        14.  
          Continuous replication configuration may fail if the continuous replication IP is not online on the master node but is online on another node
        15.  
          If you restart any node in the primary or the secondary cluster, replication may go into a PAUSED state

      Using the Veritas Access product documentation

When performing a rolling upgrade from Veritas Access 7.3.0.1 to 7.3.1 on RHEL 7.3, CIFS services get into a faulted stated after the nodes are upgraded to Veritas Access 7.3.1

After the rolling upgrade is completed on the cluster nodes, soft links are not created for the CIFS configuration files. Hence, the CIFS service do not come online. This causes the CIFS I/O path to be unavailable for a long time.

Workaround:

Create the soft links for the CIFS configuration files on every node of cluster manually as soon as the upgrade is complete on that node. This brings the CIFS services online on that node. Run the following commands on each node of the cluster after the rolling upgrade is complete on that node:

# ln -sf /opt/VRTSnas/scripts/cifs/SambaServer_online 
/opt/VRTSvcs/bin/SambaServer/online
 # ln -sf /opt/VRTSnas/scripts/cifs/cifs_va_options /etc/sysconfig/samba
