This section provides a high-level summary of the steps for setting up a Volume Replicator disaster recovery solution with SFW. For more detailed information, refer to the Volume Replicator Administrator's Guide.
These instructions do not give all the steps for setting up a cluster with Volume Replicator. For full details on clustering steps with SFW HA, see the Storage Foundation and High Availability Solutions Solutions Guide. You can refer to application-specific Solutions guide for more details on how they work with SFW HA. For example, if you use SQL Server with SFW HA, refer to the Storage Foundation and High Availability Solutions HA and Disaster Recovery Solutions Guide for Microsoft SQL.
All the guides are included on the product disc.
To set up a cluster with Volume Replicator:
For Volume Replicator, installation requires at least two servers running SFW with a network connection between them: one as the primary at the main site and the other as the secondary at a second site. Optionally, you can have additional secondary sites.
If you plan to use clustering with SFW HA or SFW and Microsoft Failover Clustering, you have several configuration choices. Probably the most common one is to have four servers, two each clustered together at each site. You can also have a cluster with two servers, one node at the primary site and the other at the secondary. Another variation is for the primary site to have a two-node cluster while the secondary site has a standalone server for replication.
InfoScale Enterprise includes Global Cluster Option (GCO), that facilitates replication support after a site failure.
Follow the instructions in the Volume Replicator documentation to configure this service, which is required for Volume Replicator commands to work properly.
You are creating the volumes to be replicated. You can create the volume for the Volume Replicator Replicator Log now or wait until you run the Volume Replicator wizard for setting up RDS on the system.
The wizard lets you either identify an existing volume for the log volume or to have the wizard bring up the screen for creating the volume so you can create the volume at that time.
On your secondary system, create a duplicate of the disk groups and volumes that are on the primary system. You can do this step in one of the two following ways:
Repeat the same manual procedures to set up the disk groups and volumes that you used previously on the primary system.
Wait until you run the Volume Replicator RDS Wizard and allow Volume Replicator to make a duplicate of the disk groups and volumes for you.
If you have installed an application on the primary site, it also needs to be installed on the secondary site.
You need to create a virtual IP resource that is used for replication for each replicated disk group. In addition, if you are using VCS, you need to specify a NIC resource. This NIC resource is not needed for a Microsoft failover cluster. Create the IP resource on both the primary and secondary sites. Each site needs its own IP address. This virtual IP should be linked to the NIC that is used for the server at each site.
