Next, you need to configure the volume manager, the Sun Cluster device groups, and the highly available cluster global file system. You can configure these entities in two ways:
By replicating the volume manager information from cluster-paris
By creating a copy of the volume manager configuration on the LUNs of cluster-newyork by using the VERITAS Volume Manager commands vxdiskadm and vxassist
Each of these methods is described in the following procedures.
If you are using storage-based replication, do not configure a replicated volume as a quorum device. The Sun Cluster Geographic Edition software does not support Hitachi TrueCopy S-VOL and Command Device as a Sun Cluster quorum device. See Using Storage-Based Data Replication in Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS for more information.
Start replication for the devgroup1 device group.

Initial configuration on the secondary cluster is now complete.
This task copies the volume manager configuration from the primary cluster, cluster-paris, to LUNs of the secondary cluster, cluster-newyork, using the VERITAS Volume Manager commands vxdiskadm and vxassist command.
The device group, devgroup1, must be in the SMPL state throughout this procedure.
Confirm that the pair is in the SMPL state.

Create VERITAS Volume Manager disk groups on shared disks in cluster-paris.
For example, the d1 and d2 disks are configured as part of a VERITAS Volume Manager disk group, which is called oradg1, by using commands, such as vxdiskadm and vxdg.
After configuration is complete, verify that the disk group was created by using the vxdg list command.
The output of this command should show oradg1 as a disk group.
Create the VERITAS Volume Manager volume.
For example, a volume that is called vol1 is created in the oradg1 disk group. The appropriate VERITAS Volume Manager commands, such as vxassist, are used to configure the volume.
