Remote Install - FAQ

Table of Contents

How does Remote Install Work?

Remote Install (also referred to as Install Software from the CommCell Console) works in conjunction with Custom Packages and Multi-Cache features, where WAN bandwidth can be drastically reduced during remote site installations.

Once the installation job starts, the CommServe pushes the required software packages to the selected computers sequentially. Once the CommServe receives notification from the client computer that the software package has been successfully delivered to the computer, it pushes the software packages to the next computer, and so on. In the meantime, the silent installation automatically begins for a computer once the packages are successfully delivered.

How can I discover EDC/Virtual Server Clients?

If you need install software packages on EDC Discovered or Virtual Server Discovered clients, you must configure the CommCell Browser to display these client types. To do this, access the User Preferences configuration from the CommCell Console's Control Panel, and enable the display options for the client types you require.

How can I perform Remote Installs in a PowerBroker Environment?

If your Unix client computers are residing in an environment that uses PowerBrokerServers for your Unix root access control, you are recommended to configure few additional settings prior to performing the remote installation. Use the following steps to install the software in a PowerBroker environment from the CommCell Console.


Verify that the computer in which you wish to install the software satisfies the System Requirements.

Required permissions

Make sure that the PowerBroker profile you use for installing the software has the following permissions:

  1. Permission to run any command from the following locations:
    • /tmp directory
    • SnapProtect install directory. For example: /opt.
  2. Permission to execute the following command:

    chmod a+x /tmp/cvpkgseed

Configuring the CommServe

Before installing the software components for the first time, you are required to configure few additional settings on the CommServe. Use the following steps to configure the CommServe.

  1. Logon to the CommServe computer as an Administrator.
  2. Click the Windows Start button, click Run, type regedit in the Open box, and then click OK.
  3. From the Registry Editor, add the registry key sCmdToExecForNonRootUsers at the following location. This registry key takes a String Value.

    HKEY_LOCAL_MACHINE\SOFTWARE\CommVault Systems\Galaxy\Instance<xxx>\Deployment

    If you do not find the Deployment key under <Instance001> , you must create it.

  4. Specify the full path to pbrun as the string value, along with the appropriate options.

    For example: /usr/local/bin/pbrun -u root

  5. Close the Registry Editor.

Once the CommServe is configured, you can proceed to install the software from the CommCell Console.
