Create the replication objects on the secondary site from the master node of the primary site, using the vradmin command.
To set up the disk group on the secondary site for replication
# 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: rac1_vol
rvg_pri is the RVG on the primary site. For example: rac1_rvg
pri_host is the virtual IP address or resolvable virtual host name of the cluster on the primary site.
For example: clus1_1
sec_host is the virtual IP address or resolvable virtual host name of the cluster on the secondary site.
For example: clus2_1
For example, the command to add the cluster on the primary site to the Replicated Data Set (RDS) is:
vradmin -g oradatadg addsec rac1_rvg \ clus1_1 clus2_1
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 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
# vradmin -g oradatadg -l printrvg
For example:
Replicated Data Set: rac1_rvg Primary: HostName: 10.180.88.187 <localhost> RvgName: rac1_rvg DgName: rac1_vol datavol_cnt: 1 vset_cnt: 0 srl: rac1_srl RLinks: name=rlk_clus2_1_rac1_rvg, detached=on, synchronous=off Secondary: HostName: 10.190.99.197 RvgName: rac1_rvg DgName: oradatadg datavol_cnt: 1 vset_cnt: 0 srl: rac1_srl RLinks: name=rlk_clus1_1_rac1_rvg, detached=on, synchronous=off
