Description

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

Setup

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.

---
dmmultipath::enabled_devices:
  - 'ibm_2145'
include 'dmmultipath'

Usage

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'],
}
