How to Make the Original Primary Cluster Primary for a Hitachi TrueCopy Protection Group

Steps

1. Deactivate the protection group on the original primary cluster.

   phys-paris-1# geopg stop -e Local tcpg

2. Resynchronize the configuration of the protection group.

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

   phys-paris-1# geopg update tcpg

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

   cluster-paris: tcpg role: Primary cluster-newyork: tcpg role: secondary

3. Activate the protection group on both clusters in the partnership.

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

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