To set up the disk group on the secondary site for replication

1. Issue the command in the following format from the cluster on the primary site:

   # vradmin -g dg_pri addsec rvg_pri pri_host sec_host
   					

   where:

   • dg_pri is the disk group on the primary site that VVR will replicate. For example: dbdata_vol

   • rvg_pri is the Replicated Volume Group (RVG) on the primary site. For example: dbdata_rvg

   • pri_host is the virtual IP address or resolvable virtual host name of the cluster on the primary site.

     For example: 10.10.9.101 or clus1

   • sec_host is the virtual IP address or resolvable virtual host name of the cluster on the secondary site.

     For example: 10.11.9.102 or clus2

   For example, the command to add the cluster on the primary site to the Replicated Data Set (RDS) is:

   vradmin -g dbdatadg addsec dbdata_rvg clus1 clus2

   or

   vradmin -g dbdatadg addsec dbdata_rvg 10.10.9.101 10.11.9.102

   On the secondary site, the above command performs the following tasks:

   • Creates an RVG within the specified disk group using the same name as the one for the primary site

   • Associates the data and Storage Replicator Log (SRL) volumes that have the same names as the ones on the primary site with the specified RVG

   • Adds a data change map (DCM) for the data volume

   • Creates cluster RLINKs for the primary and secondary sites with the default names; for example, the "primary" RLINK created for this example is rlk_dbdata_clus2_dbdata_rvg and the "secondary" RLINK created is rlk_dbdata_clus1_dbdata_rvg.

     If you use 10.10.9.101 and 10.11.9.102, creates cluster RLINKs for the primary and secondary sites with the default names; for example, the "primary" RLINK created for this example is rlk_10.11.9.102_dbdata_rvg and the "secondary" RLINK created is rlk_10.10.9.101_dbdata__rvg.

2. Verify the list of RVGs in the RDS by executing the following command.

    # vradmin -g dbdatadg -l printrvg

   For example:

   Replicated Data Set: dbdata_rvg
   Primary:
   HostName: 10.180.88.187 <localhost>
   RvgName: dbdata_rvg
   DgName: dbdata_vol
   datavol_cnt: 1
   vset_cnt: 0
   srl: dbdata_srl
   RLinks:
   name=rlk_clus2_dbdata_rvg, detached=on,
   synchronous=off
   Secondary:
   HostName: 10.190.99.197
   RvgName:dbdata_rvg
   DgName: dbdatadg
   datavol_cnt: 1
   vset_cnt: 0
   srl: dbdata_srl
   RLinks:
   name=rlk_clus1_dbdata_rvg, detached=on,
   synchronous=off

   Note:

   Once the replication is started the value of the detached flag will change the status from ON to OFF.
