given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

This module configures the DM Multipath module for a given device or set of devices.


There are no external dependencies for this module aside from standard system packages.

Beginning with dmmultipath

For this module to work the class must be included with at least one enabled storage controller.

class { 'dmmultipath':
  enabled_devices => ['ibm_2145'],

This can also be achieved via hiera.

  - 'ibm_2145'
include 'dmmultipath'


The base configuration will provide sane defaults for the ibm_2145 device, enable the multipathd service at boot, and configure a 120 second timeout for all corresponding disk devices via udev. In addition, a regeneration of the initramfs for the current kernel can also be configured. This ensures that the appropriate multipath settings are available from the time of boot.

class { 'dmmultipath':
  regen_initramfs => true,
  enabled_devices => ['ibm_2145'],


Operating System Support

  • RedHat Family 7.x (CentOS and RHEL)

Controller Support

A full listing of supported types can be found in the definition of the Dmmultipath::SupportedModels type.
