1.4. DM-Multipath Setup Overview

DM-Multipath includes compiled-in default settings that are suitable for common multipath configurations. Setting up DM-multipath is often a simple procedure.
The basic procedure for configuring your system with DM-Multipath is as follows:
  1. Install device-mapper-multipath rpm.
  2. Edit the multipath.conf configuration file:
    • comment out the default blacklist
    • change any of the existing defaults as needed
    • save the configuration file
  3. Start the multipath daemons.
  4. Create the multipath device with the multipath command.
Detailed setup instructions for several example multipath configurations are provided in see Chapter 3, Setting Up DM-Multipath.
