Before creating an RDS, check whether your setup meets the following prerequisites:

• Verify that the disk groups and volumes for the SQL user database files and log files have been created. You can create the Replicator Log volume while you run the wizard if not created earlier.

• Verify that VxSAS has been configured.

• Verify that the SQL virtual server Network Name resource is offline on the secondary site. This would also bring all the dependent SQL resources offline. If on the same subnet, ensure that the SQL IP address resource is also offline.

• Verify that the intended Primary host is connected to VEA, if you configure the RDS from a remote client or from a host that is not the Primary.

• Verify that you set the IP preference, whether Volume Replicator should use IPv4 or IPv6 addresses, before you configure replication. The default setting is IPv4.

  When you specify host names while you configuring replication, Volume Replicator resolves the host names with the IP addresses associated with them. This setting determines which IP protocol Volume Replicator uses to resolve the host names.

  Use Veritas Enterprise Administrator (VEA) (Control Panel > VVR Configuration > IP Settings tab) to set the IP preference.

• Verify that the data volumes and Replicator Log volume that intended to be a part of the RDS are not of the following types, as Volume Replicator does not support the following types of volumes:

  • Storage Foundation (software) RAID-5 volumes

  • Volumes with the Dirty Region Log (DRL)

  • Volumes with a comma in their names

  • Secondary volume of a size smaller or greater than that on the Primary

  • Volume that is under replication

    For the Replicator Log volume, in addition to these types, make sure that the volume does not have a DCM.
