Preinstallation Checklist for High Availability Computing
CommServe Failover monitors the status of the active and passive CommServe hosts and allows you to fail over CommCell operations to the standby host when the production CommServe host is down. For more information, see CommServe Recovery Using a High Availability Standby CommServe Host.
Use this preinstallation checklist to prepare the computer in which the High Availability Computing package will be installed and to gather all of the information you will need during the installation.
Verify System Requirements
Verify that the computer where you will install High Availability Computing satisfies the hardware requirements specified in System Requirements.
Verify License Requirements
The CommServe Failover component does not require a license.
Determine the Installation Location
Install the CommServe Failover on the following computers:
- Production and standby CommServe hosts.
Make sure a SQL Server Agent is installed in a separate instance on the production and standby CommServe hosts. The CommServe Failover component must be installed to the same instance as the SQL Server Agent.
- Individual Windows host acting as Witness Server in the standby CommServe location. You can also use an existing MediaAgent computer to act as the Witness Server. If the MediaAgent computer is in the same location as the production CommServe computer, then install the failover component on a Windows host in the standby CommServe location.
All the hosts with CommServe Failover must be able to communicate with each other using TCP/IP.
Login to the host computer as member of the Administrators group.
Gather Installation Data
Refer to the items in this section to gather the information that you will need during the installation. Record the information before you begin installing the software, so you can refer to it during the installation.
You can install the CommServe Failover only by using the installation package that was created by the Download Manager.
Install Instance Selection
For CommServe hosts with multiple instances, select instance with SQL Server Agent (e.g. Instance002). Install Instance on the CommServe hosts must be the same as that of the SQL Server Agent. Any/Default instance can be used for the Witness Servers.
Commvault package to install
Install the CommServe Failover package, which is listed under the Tools category.
Note: To gather the required information for the File System Agent, refer to the Gather Installation Data section in the Preinstallation Checklist for the Windows File System Agent.
Client computer details
If the File System Agent, or another package, is already installed on the computer, you are not required to gather all the computer details again. The level of detail depends on how the package you selected is installed:
If you are using DNS for the failover configuration, specify the floating CommServe host name. The production and standby CommServe hosts use the same floating CommServe host name.
