Displaying the RLINK information for all the hosts in the RDS

The vrstat -R command displays detailed statistics for the RLINKs on all the hosts in an RDS. This information can be used to assess connectivity and network problems between the hosts. The vrstat -R command can be executed from the Primary and the Secondary. The output of this command is a combination of the outputs of the vxrlink stats and vxrlink status commands.

To view information about all the RLINKs in an RDS:

# vrstat -R [local_rvgname]

The argument local_rvgname is the name of the RVG on the local host and is optional. The local RVG name represents its RDS.

If you specify the local_rvgname name, the vrstat -R command displays the information for all the RLINKs for the specified RVG. Otherwise, the command displays the information for all the RLINKs for all the RDSs. For an RVG in a shared disk group, the host_name is the logowner and the displayed information reflects activity on the logowner.
