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 LiveSync For High Availability Disaster Recovery.

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

  • CommServe Server

    No special licenses are required for setting up the CommServe server.

  • SQL Server Agent

    You must have two Microsoft SQL Server agent licenses, one for the production CommServe host and the other for the standby CommServe host.

For information about licensing, see the Commvault Licensing Program Guide.

Determine the Installation Location

Install the CommServe Failover on the 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.

All of the hosts with CommServe Failover must be able to communicate with each other using TCP/IP.

Log in 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.

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.

Commvault package to install

Install the CommServe Failover package, which is listed under the Tools category.

  • If the File System Agent is not installed on the computer, the File System Core and File System packages are automatically installed with the package that you selected. The File System Agent will not consume any licenses.

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:

  • For installations using the CommCell Console, the installation program requests only the name of the client computer.

  • For installations using the installation package, the installation program reads the details from the previous installation.

CommServe Name

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.
