1.5. 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 the device-mapper-multipath rpm.
  2. Create the configuration file and enable multipathing with the mpathconf command. You can also start the multipath daemon with this command if you do not need to edit the configuration file.
  3. If necessary, edit the multipath.conf configuration file to modify default values and save the updated file.
  4. Start the multipath daemon.
For detailed setup instructions for multipath configuration see Chapter 3, Setting Up DM-Multipath.
