3.3. Configuring Storage Devices
3.3. Configuring Storage Devices By default, DM Multipath includes support for the most common storage arrays that themselves support DM Multipath. For information on the default configuration value, including supported devices, run either of the following commands. If you need to add a storage device that is not supported by default as a known multipath device, edit the /etc/multipath.conf file and insert the appropriate device information. For example, to add information about the HP Open-V series the entry looks like this. This example sets the device to queue for a minute (or 12 retries and 5 seconds per retry) after all paths have failed. For more information on the devices section of the configuration file, see Section 4.5, "Configuration File Devices" .
multipathd show config multipath -t devices { device { vendor "HP" product "OPEN-V" no_path_retry 12 } }
