The following error is displayed while trying to delete an RDS, add, or delete a volume:

Operation failed, target host not responding.

If you have lost one of the Secondary hosts permanently (due to disaster, or system failure or such other causes) or attempt certain operations after migration or takeover, above mentioned operations may fail. This is because you have RLINKs to the Secondary hosts which are no longer accessible.

Remove the links to Secondary hosts which are no longer accessible by running the following command on the host on which the error occurred:

vxprint -l <rvg>

This command displays the RLINKs to the specific RVG. Identify the RLINK to the Secondary hosts which are no longer accessible by using the information in the field remote_host. For these RLINKs, run the following command:

vxrlink -f rm <rlink>

You can now delete the RDS and add or delete the volumes.
