Setting Up Your SPS Environment
Now that the requirements have been determined and LifeKeeper configuration has been mapped,
components of this SPS environment can be set up.
Note: Although it is possible to perform some setup tasks in a different sequence, this list is provided
in the recommended sequence.
Installing the Linux OS and Associated Communications
Packages
Before attempting to install the SPS for Linux software, you must first ensure that your Linux
operating system is successfully installed and operational. Please see the Linux installation
instructions provided with your distribution of Linux for complete installation details.
Note:
l It is possible to install Linux after connecting and configuring your shared storage, but it may
be simpler to have Linux installed and running before introducing new peripheral devices.
l The SPS for Linux Installation Image File provides a set of installation scripts designed to
perform user-interactive system setup tasks and installation tasks for installing SPS on your
system.
Connecting Servers and Shared Storage
If you are planning to use LifeKeeper in a non-shared storage environment, then you may skip this
information. If you are using LifeKeeper in a data replication (mirroring) environment, see the
DataKeeper section of this documentation. If you are using LifeKeeper in a network attached storage
environment, see LifeKeeper Network Attached Storage Recovery Kit Administration Guide.
Once Linux is installed, you should set the host adapter and shared peripheral addressing. Refer to
the documentation accompanying your adapter and storage device for specific details.
Configuring Shared Storage
LifeKeeper configurations may use the facilities of shared Small Computer System Interface (SCSI)
host adapters and shared disk hardware to switch resources from a failed server to a designated
backup server. A Fibre Channel Storage Area Network (SAN) may also be used to switch resources
from a failed server to a designated backup server.
Perform the following tasks before creating disk-based application resource hierarchies that enable
LifeKeeper to provide failover protection.
