Control Service Installation Considerations

You need to install either one Control Service or two Control Services, depending on the type of procedure you want to perform on the Control Service itself:

• For standard CA ARCserve RHA Replication and HA operations, you only need to install one Control Service. This Control Service will function as the single-point-of-control for all CA ARCserve RHA operations. If you want to replicate the Control Service data WITHOUT performing switchover between two Control Services, you can also install only one Control Service.

  Note: To replicate the Control Service data, you will need to create Replication Control Service scenario using the Manager, after you finished installing all CA ARCserve RHA components is completed.

• For replicating the Control Service data and switching roles between the original Control Service and a standby Control Service, you need to install two Control Services. One of the installed Control Service will function as the active Control Service, while the other will function as the standby Control Service. For installing two Control Services, you need to repeat the installation process twice, since you can only install one Control Service at a time.

  Notes:

  • To apply HA solution on the Control Service, you will need to create HA Control Service scenario using the Manager, after the installation of all CA ARCserve RHA components is completed.
  • You do NOT need an HA license to apply HA solution on the Control Service. However, you do need to register CA ARCserve RHA before creating a scenario for the Control Service.
  • For more information about creating Replication and HA Control Service scenarios, refer to the CA ARCserve RHA Administration Guide.
