3. Migrating Services That Use Hitachi TrueCopy and Universal Replicator Data Replication
A. Geographic Edition Properties for Hitachi TrueCopy and Universal Replicator
You can resynchronize the configuration information of the local protection group with the configuration information that is retrieved from the partner cluster. You need to resynchronize a protection group when its Synchronization status in the output of the geoadm status command is Error.
For example, you might need to resynchronize protection groups after booting the cluster. For more information, see Booting a Cluster in Oracle Solaris Cluster Geographic Edition System Administration Guide.
Resynchronizing a protection group updates only entities that are related to Geographic Edition software. For information about how to update Oracle Solaris Cluster entities, see Replicating and Upgrading Configuration Data for Resource Groups, Resource Types, and Resources in Oracle Solaris Cluster Data Services Planning and Administration Guide.
Before You Begin
The protection group must be deactivated on the cluster where you are running the geopg update command. For information about deactivating a protection group, see Deactivating a Hitachi TrueCopy or Universal Replicator Protection Group.
You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Geographic Edition Software and RBAC in Oracle Solaris Cluster Geographic Edition System Administration Guide.
# geopg update protectiongroupname
Specifies the name of the protection group
Example 2-24 Resynchronizing a Protection Group
