The LifeKeeper for Linux software, including Optional LifeKeeper Recovery Kits, is contained within a single image file (sps.img).
LifeKeeper for Linux Installation Image File
The LifeKeeper for Linux image file (sps.img) provides a set of installation scripts designed to perform the user interactive system setup tasks that are necessary when installing LifeKeeper on your system (see Interactive Way for more information). A non-user interactive install can be performed as well (see Non-interactive Way for more information).
The LifeKeeper installation process is broken down into 3 steps:
- Selection (user interactive only)
- Installation and Configuration
The first step of the process is the Collection phase and is responsible for collecting information about the system, such as the Linux distribution being used, to ensure the system meets the requirements for a successful install. Step 2 of the process is the Selection phase and is responsible for interacting with the user via a menu based selection process to determine what LifeKeeper packages to install and the configurations required to support those selections. The third and final step is the Installation and Configuration phase. This step is responsible for installing the LifeKeeper Core Package Cluster and Optional Recovery Software, and configuring the system for LifeKeeper. This step also installs any required OS supporting packages that are not already on the system.
The LifeKeeper for Linux image file includes a core package cluster containing the following software packages:
LifeKeeper Core Package Cluster
- LifeKeeper (steeleye-lk). The LifeKeeper core packages provide recovery software for core system components, such as memory, CPUs, the operating system, the SCSI disk subsystem and file systems.
- LifeKeeper GUI (steeleye-lkGUI). The LifeKeeper GUI package provides a graphical user interface for LifeKeeper administration and monitoring.
- DataKeeper (steeleye-lkDR). The DataKeeper package provides data replication (synchronous or asynchronous mirrors) with intent logging.
- IP Recovery Kit (steeleye-lkIP). The LifeKeeper IP Recovery Kit provides switchover software for automatic recovery of IP addresses.
- Raw I/O Recovery Kit (steeleye-lkRAW). The LifeKeeper Raw I/O Recovery Kit provides support for applications that use raw i/o to bypass kernel buffering.
- Man Pages (steeleye-lkMAN). The LifeKeeper Man Page package provides reference manual pages for the LifeKeeper product.
Optional Recovery Software
Recovery kits are also released with the LifeKeeper Core software. During the installation, you will be presented with a complete, up-to-date, selectable list of available recovery kits. For information regarding these recovery kits, see the Application Recovery Kits section of the LifeKeeper for Linux Technical Documentation.
