Resynchronizing a Hitachi TrueCopy Protection Group

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 Sun Cluster Geographic Edition System Administration Guide.

Resynchronizing a protection group updates only entities that are related to Sun Cluster Geographic Edition software. For information about how to update Sun Cluster entities, see Replicating and Upgrading Configuration Data for Resource Groups, Resource Types, and Resources in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

How to Resynchronize a Protection Group

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 Protection Group.

1. Log in to a cluster node.

   You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC in Sun Cluster Geographic Edition System Administration Guide.

2. Resynchronize the protection group.

   # geopg update protectiongroupname

   protectiongroupname

   Specifies the name of the protection group
