Because the various supported Linux distributions use different package managers for online installation, the procedure for installing, upgrading, or removing Agent on any supported Linux OS depends on the package manager used. The package managers, and the Linux distributions they support, are described in the following table. Table 9. Package managers and the Linux distributions they support Package Manager Linux Distribution yum Linux distributions based on Red Hat Enterprise Linux (RHEL), including RHEL, CentOS, and Oracle Linux. zypper SUSE Linux Enterprise Server (SLES) versions 11, 12 apt Linux distributions based on Debian, including Debian 7 or 8, and Ubuntu 12.04 and later As a one-time setup step for each Linux machine, you must configure your local software repository to point to the location where the package manager obtains Dell Rapid Recovery installation files. NOTE: This process is represented by steps 1 through 4 in each of the installation procedures. When upgrading future editions of the Rapid Recovery Agent on a Linux machine with the repository configured, you will not need to perform these steps. After you configure a software repository on your Linux machine, the package manager is able to retrieve and install the packages needed for installation or removal of Rapid Recovery Agent software and related components, such as aamount (now called local mount), aavdisk (now called rapidrecovery-vdisk), and Mono (an open source, Ecma standard-compliant, .NET Frameworkcompatible tool set used for porting the Agent software to Linux platforms). For each package manager, you can run the appropriate command at the command line to determine if it is configured to download Rapid Recovery packages. These commands are listed in the following table. Table 10. Command to show package manager repository configuration Package Manager Command to list configured repositories yum yum replolist zypper zypper repos apt ls /etc/apt/sources.list.d Previous versions of the AppAssure Agent software must be completely removed from a Linux machine before installing the Rapid Recovery Agent version and protecting the Linux machine using the Rapid Recovery Core. This is true for online or offline installations. Removing AppAssure Agent employs the use of shell scripts. The uninstall instructions differ, depending on the Linux distribution you are using. For more information on uninstalling AppAssure Agent from a Linux machine, see the topic "Uninstalling the AppAssure Agent software from a Linux machine" in the Dell Data Protection | Rapid Recovery 6.0 Installation and Upgrade Guide. NOTE: Removal of the new Rapid Recovery Agent software uses the package manager for each distribution. Therefore, if uninstalling a version of Rapid Recovery Agent, see the appropriate procedure under the topic see the topic "Uninstalling the AppAssure Agent software from a Linux machine" in the Dell Data Protection | Rapid Recovery 6.0 Installation and Upgrade Guide. If installing Rapid Recovery Agent on a Linux machine that has never had AppAssure Agent installed, determine the appropriate package manager from the preceding table. Then follow the appropriate installation procedure. After configuring the newly installed Agent software on a Linux machine, you must restart the machine. Restarting ensures that the proper kernel driver version is used to protect your machine. Thus, the installation process when upgrading from AppAssure to Rapid Recovery involves: • Removing the AppAssure Agent software (not required for first-time installations) • Determine the relevant package manager for your Linux distribution • Follow the procedure for installing Rapid Recovery Agent on the Linux machine, including configuring the software repository (steps 1 through 4 of the installation procedure) • Run the configuration utility to set port, configure users, add firewall exclusions, install the kernel module, and start the Agent service. 30
