Task 2: Preparing the Configuration File
To setup multipathing with VTrak, or any other subsystem, you must provide the
required device attributes in a configuration file. The multipath configuration file is
named multipath.conf. The functional version of the file is saved in the /etc
directory.
RedHat Systems
For RedHat systems, there is a default /etc/multipath.conf file. However, the
default file does not have the required device attributes to work with VTrak.
There are also sample configuration files in the /usr/share/doc/device-mapper-
multipath-[version] directory:
• multipath.conf.annotated – multipath device attributes listed and defined
• multipath.conf.synthetic – multipath device attributes listed only
SuSE Systems
For SuSE systems, there is no default /etc/multipath.conf file.
There are sample multipath configuration files in the /usr/share/doc/packages/
multipath-tools directory:
• multipath.conf.annotated – multipath device attributes listed and defined
• multipath.conf.synthetic – multipath device attributes listed only
Editing a Configuration File
You must provide a configuration file with required device attributes to work with
VTrak. See the sample configuration file on page 402.
Take the following actions to prepare a configuration file:
1. Choose an existing multipath.conf file and open the file in a text editor.
2. Save a working copy of the file under another name.
3. Edit the file to include the following line under defaults:
defaults {
user_friendly_names yes
}
