How to Force Immediate Takeover of Hitachi TrueCopy Services by a Secondary Cluster

Before You Begin

Before you force the secondary cluster to assume the activity of the primary cluster, ensure that the following conditions are met:

• Sun Cluster Geographic Edition software is running on the cluster.

• The cluster is a member of a partnership.

• The Configuration status of the protection group is OK on the secondary cluster.

1. Log in to a node in the secondary cluster.

   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. Initiate the takeover.

   # geopg takeover [-f] protectiongroupname

   -f

   Forces the command to perform the operation without your confirmation

   protectiongroupname

   Specifies the name of the protection group

Example 3–2 Forcing a Takeover by a Secondary Cluster

This example forces the takeover of tcpg by the secondary cluster cluster-newyork.

The phys-newyork-1 cluster is the first node of the secondary cluster. For a reminder of which node is phys-newyork-1, see Example Sun Cluster Geographic Edition Cluster Configuration in Sun Cluster Geographic Edition System Administration Guide.

phys-newyork-1# geopg takeover -f tcpg

Next Steps

For information about the state of the primary and secondary clusters after a takeover, see Appendix C, Takeover Postconditions, in Sun Cluster Geographic Edition System Administration Guide.
