Uninstalling Commvault Locally from UNIX and Linux Clients

You can uninstall Commvault packages from a client or MediaAgent computer by using the Commvault uninstallation command.

Note: To uninstall UNIX native packages, you must use the steps described in Uninstalling UNIX Native Packages.

Before You Begin

For a successful uninstallation, you must review some preparation tasks for the software package that you want to uninstall. For more information, see Prepare to Uninstall Commvault from Client and MediaAgent Computers.

Procedure

Interactive Uninstallation

1. Log on to the computer as root.

2. At the command line, run the following command:

   cvpkgrm

   If there are multiple instances installed on the client, select the instance from where you want to uninstall the software and press Enter.

3. On the Welcome to Uninstaller dialog, click Next.

4. On the Uninstall Selection dialog, choose how you want to uninstall packages:

   • To uninstall all packages, select Remove all the packages and click Next.

     Tip: If the client cannot communicate with the CommServe computer, select Remove all packages locally. Commvault will be removed from the client without contacting the CommServe computer. This operation is called decoupled uninstallation. After the uninstallation, you must deconfigure the client.

   • To uninstall specific packages, do the following:

     1. Select Select packages to remove and click Next.

     2. On the Package Selection page, select the packages that you want to uninstall and then click Next.

        Important: If you select the File System Core, all Commvault packages will be uninstalled. Commvault packages are dependent on the File System Core.

5. On the Summary dialog, review the information and then click Next.

6. On the Uninstall Status dialog, click Finish.

   If you uninstalled all packages, the client is displayed as unavailable in the CommCell Browser pane of the CommCell Console.

Unattended Uninstallation

• To uninstall the software on the client, run the following command:

   
  cvpkgrm -i InstanceNNN

  where InstanceNNN is the name of the instance from where you want to uninstall the software. If you only have one instance installed on the client, then specify Instance001.

What to Do Next

• If the client did not communicate with the CommServe computer, you must deconfigure the client from the CommCell Console.

  Deconfiguring the client is the process of releasing the licenses used by the client. For instructions, see Releasing a License (Deconfiguration).

• You can continue to browse the client data and perform out-of-place restores. However, if you no longer need the client data, you can delete the client from the CommCell Console. For instructions, see Deleting a Client Computer.
