Sun Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy and Universal Replicator

ProcedureHow to Make the Original Secondary Cluster Primary for a Hitachi TrueCopy or Universal Replicator Protection Group

  1. Resynchronize the configuration of the protection group.

    This command updates the configuration of the protection group on cluster-newyork with the configuration information of the protection group on cluster-paris.

    phys-newyork-1# geopg update tcpg

    After the geopg update command completes successfully, tcpg has the following role on each cluster:

    		tcpg role: Secondary
    		tcpg role: Primary
  2. Activate the protection group on both clusters in the partnership.

    phys-newyork-1# geopg start -e Global tcpg

    This command starts the application on cluster-newyork. Data replication starts from cluster-newyork to cluster-paris.

    Caution – Caution –

    This command overwrites the data on cluster-paris.
