Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

■ Setting up both clusters as part of a global cluster environment.
See “About setting up a global cluster in an SFCFS environment” on page 312.
■ Setting up replication for clusters at both sites.
See “Setting up replication using VVR on the primary site” on page 324.
See “Setting up replication using VVR on the secondary site” on page 327.
■ Starting replication of the database.
See “Starting replication of application database volume” on page 331.
■ Configuring VCS for replication on clusters at both sites.
See “Configuring VCS to replicate the database volume using VVR” on page 333.
Setting up replication using VVR on the primary site
Setting up replication with VVR in a global cluster environment involves the
following tasks:
■ If you have not already done so, create a disk group on the storage on the
primary site.
■ Creating the Storage Replicator Log (SRL) in the disk group for the database.
See “Creating the SRL volume on the primary site” on page 324.
■ Creating the Replicated Volume Group (RVG) on the primary site.
See “Setting up the Replicated Volume Group (RVG) on the primary site”
on page 325.
Creating the SRL volume on the primary site
Create the SRL. The SRL is a volume in the RVG. The RVG also holds the data
volumes for replication.
■ The data volume on the secondary site has the same name and the same size
as the data volume on the primary site.
■ The SRL on the secondary site has the same name and the same size as the
SRL on the primary site.
■ The data volume and SRL volume should exist in the same disk group.
■ If possible, create SRLs on disks without other volumes.
■ Mirror SRLs and data volumes in the absence of hardware-based mirroring.
