Verifying the required multipathing packages

It is a good practice to verify that you have the multipathing packages that enable you to use DM-Multipath. These packages are part of your Linux distribution.


  1. Use the rpm -q command to display information about the name and version of the DM-Multipath package that you have installed.
    If you are using... Enter the following command...
    Red Hat Enterprise Linux
    • rpm -q device-mapper
    • rpm -q device-mapper-multipath
    SUSE Linux Enterprise Server
    • rpm -q device-mapper
    • rpm -q multipath-tools
  2. If you do not have the required packages, get a copy of your operating system RPM and install the multipathing package.
