veritas: rlinks in 'paused due to network disconnection' state

Had a case open with Symantec with the following issue.

 # vradmin -g dgprdap2 repstatus rvg_prdap2
 Replicated Data Set: rvg_prdap2
 Primary:
   Host name:                  10.150.150.13
   RVG name:                   rvg_prdap2
   DG name:                    dgprdap2
   RVG state:                  enabled for I/O
   Data volumes:               1
   VSets:                      0
   SRL name:                   srl_prdap2
   SRL size:                   25.00 G
   Total secondaries:          1

 Secondary:
   Host name:                  10.150.150.16
   RVG name:                   rvg_prdap2
   DG name:                    dgprdap2
   Data status:                consistent, behind
   Replication status:         paused due to network disconnection
   Current mode:               asynchronous
   Logging to:                 SRL (213278 Kbytes behind, 0% full)
   Timestamp Information:      behind by 2668h 22m 7s

 'vradmin repstatus' shows rlinks in 'paused due to network disconnection' state

Various attempts where made to try continue/attach or resume the replication but failed.  

The following checks must be made to diagnose the problem.

Run the vrport command on both the primary and secondary nodes.

# /usr/sbin/vrport

Check communication on these ports, from primary to secondary and vice versa on each node: 

# ping -p port-number host-name

If the ping command succeeds, try restarting the VVR daemons (both on primary and secondary) in the correct sequence: 

 

Stop vradmin on secondary then on primary

# /usr/sbin/vxstart_vvr stop

Start vradmin on secondary then on primary

# /usr/sbin/vxstart_vvr start 

If for any unknown reason the above does not fix the issue you might need to try to restart the primary and secondary nodes. But if you encounter that a bounce does not fix issue it's a rare possibility that you might need to re-create the rvg's as it was in my case. Another unsolved VVR mystery.
