Configuring a global SFCFSHA cluster requires the coordination of many component setup tasks. The following procedures provide guidelines.

Tasks required to set up a global cluster:

Configure a cluster at the primary site.

See Configuring an SFCFSHA global cluster at the primary site.
Configure a cluster at the secondary site.

See Configuring an SFCFSHA cluster at the secondary site.
Configure replication on clusters at both sites.

See Configuring replication for SFCFSHA clusters at both sites.
Configure VCS service groups for replication.

See Modifying the ClusterService group for a global SFCFSHA cluster.

See Defining the remote SFCFSHA cluster and heartbeat objects.

See Configuring the VCS service groups for global SFCFSHA clusters.
Test the HA/DR configuration.
Upon successful testing, bring the environment into production.

SFCFSHA HA/DR configuration tasks may require adjustments depending upon your particular starting point, environment, and configuration, as the details of your configuration may differ from the examples given in the procedures. Review the installation requirements and sample cluster configuration files for primary and secondary clusters.

Review the requirements information to make sure your configuration is supported for SFCFSHA.

SFCFSHA supports the following replication technologies through the use of Veritas replication agents:

Table: Supported replication options for SFCFSHA global clusters

Replication technology	Supported modes	Supported software
Veritas Volume Replicator (VVR) Supporting agents RVGShared RVGSharedPri RVGLogOwner	Asynchronous replication Synchronous replication	Host-based replication
EMC SRDF Supporting agent: SRDF	Asynchronous replication Synchronous replication	All versions of Solutions Enabler
Hitachi True Copy Supporting agent: HTC	Asynchronous replication Synchronous replication	All versions of the Hitachi CCI
IBM Metro Mirror Supporting agent: MetroMirror	Synchronous replication	All versions of IBM DSCLI. The MetroMirror agent is supported for DS6000 and DS8000 arrays
IBM SVC SVC CopyServices	Asynchronous replication Synchronous replication	SSH access to the SVC
EMC Mirror View Supporting agent:MirrorView	Asynchronous replication Synchronous replication: only individual LUNs may be replicated	All versions of NaviCLI

Note:

Check your vendor's compatibility list for the supported software versions. The support listed above only exists if the host, HBA, and array combination is in your vendor's hardware compatibility list. Check your array documentation.

Note:

All arrays must support SCSI-3 persistent reservations for SFCFSHA.

You can use the Veritas replication agents listed in the table above for global clusters that run SFCFSHA. The Veritas replication agents provide application failover and recovery support to your replication configuration. The agents provide this support for environments where data is replicated between clusters.

VCS agents control the direction of replication. They do not monitor the progress or status of replication. The replication agents manage the state of replicated devices that are attached to SFCFSHA nodes. The agents make sure that the system which has the resource online also has safe and exclusive access to the configured devices.
