Replication can be set up using VVR or various third-party replication technologies.
Set up replication according to the following best practices:
Set up the replication. If you plan to use third-party software replication technology (Oracle Dataguard, IBM DB2HADR, etc.) or third-party hardware replication technology (EMC SRDF, Hitachi TrueCopy, IBM SVCCopyServices, etc.), review the vendor documentation for planning and configuring replication.
Once the replication is configured, verify that the replicated storage is visible to all the nodes in the cluster(s).
Verify that the storage vendor tools (CLIs or APIs) are installed on the VCS nodes as recommended in the respective replication agents Installation and Configuration Guide. For example, install RAID Manager CCI on each of the cluster nodes if you are using HITACHI TrueCopy replication.
Download and install the required VCS replication agent from https://sort.symantec.com/agents.
Configure the replication agent resources using guidelines from the replication agent's Installation and Configuration Guide.
Using the scenarios provided in the Install and Configuration Guide, test failover for the configuration.
