Installing Packages
The easiest and most effective way to install the device mapper and multipath
tool is during OS installation. The device mapper installs by default, regardless
of the configuration you select. However, you must manually specify the
multipath tool, as it does not install as a part of any of the configurations of
either OS. The multipath tool is listed as an option under Base System.
For hosts with the OS already installed, you can add the device mapper and
multipath tool, if they are missing.
Example: To add the multipath tool for RHEL 5.x, do the following actions:
1. Open a terminal window.
