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

Steps

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 has successfully executed, tcpg has the following role on each cluster:

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

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

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

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

   Caution –

   This command will overwrite the data on cluster-paris.
