CommServe Failover Using Commvault Network Gateway

You can create a Commvault network gateway to route requests and responses between the CommServe and network gateway-enabled clients. The Commvault network gateway is created for disaster recovery, when you want to move CommCell operations to a Standby CommServe host.

By using a Commvault network gateway, you are not required to update the DNS or host file entry with the CommServe host name on all the client computers after a disaster recovery.

Depending on the CommCell environment and your disaster recovery requirements, you can configure one or more Commvault network gateways for alternate routing.

The Commvault network gateway discussed here is used only in the event of a disaster. If you have other Commvault network gateways in the disaster recovery site, and if these network gateways are not used for other CommCell operations like regular backup and restores, turn off the CommCell Services on these network gateways, and turn them back on only in the event of a disaster. This will avoid using these disaster recovery network gateways for routing regular network traffic.

Prerequisites

  • Prepare the standby CommServe host by installing the CommServe software and applicable service packs and updates.

    For detailed information, see Installing the Standby CommServe Host.

  • Make sure that CommCell services are turned off in the standby CommServe host.
  • The Commvault network gateway must be located in a safe place not affected by a disaster impacting the production CommServe host.

Procedure

Perform the following tasks to set up a Commvault network gateway for the disaster recovery environment:

  1. Configure Commvault network gateway.
  2. Configure the network gateway settings on the client computer group.
  3. Add the client computer group to the Commvault network gateway.
  4. Configure network gateway settings on the CommServe client computer.
  5. Push the network configuration to each component in the following order:
    • Client computer groups
    • Commvault network gateway
    • CommServe client computer
