Setting Up Failovers Using a Floating CommServe Name

You can use a floating CommServe hostname to setup the CommServe failover. (A floating CommServe name is merely a DNS alias that points to an existing CommServe server.)

Method 1 (Recommended)

1. Install the production and standby CommServe hosts using its own local host name. For more information, see the following procedures"

   • Installing the Production CommServe Host

   • Installing the Standby CommServe Host

2. Create a unique floating name for each of the production and standby CommServe hosts that you plan to setup in your environment. For more information, see Setting Up DNS Entries for a Floating CommServe Name.

3. Manually configure multiple CommServe hostnames for CommServe disaster recovery, where the clients in the CommCell must have a different CommServe hostname/IP address to reach the production and standby CommServe hosts. For more information, see Configuring Multiple CommServe Hostnames for Disaster Recovery.

Additional Information

If you plan to use a combination of proxy and a floating CommServe hostname in your environment, setup client communication with the CommServe using either the Using failover Clients or the Proxy Client option in the CommServe LiveSync dialog box.

   • Installing the Production CommServe Host

   • Installing the Standby CommServe Host
