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.
2. Type the following command and press
Enter
:
# rpm -ivh device-mapper-multipath-0.4.7-8.el5.i386.rpm
The system returns the following lines:
Preparing... ##################### [100%]
1:device-mapper-multipath##################### [100%]
#
(or a similar message)
Important
Where possible, obtain the device mapper and multipath tool from the original installation
CDs to ensure full compatibility with your existing OS. Refer to your OS documentation
for more information.
