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.)
Note
Recommended: Use Commvaults in-built ability to configure multiple hostnames for High Availability CommServe Host setup, to perform the failover. For more information, see Configuring Multiple CommServe Hostnames for Disaster Recovery.
Method 1 (Recommended)
-
Install the production and standby CommServe hosts using its own local host name. For more information, see the following procedures"
-
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.
-
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.
Method 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.
-
Install the production and standby CommServe hosts using its unique floating name. For more information, see the following procedures"
Result
-
The above steps ensure that the hostname associated with the CommServe hosts to remain virtual.
-
Also allows the Commvault software to automatically publish multiple floating names to all the clients for communication between the CommServe hosts and clients.
