By default, DM-Multipath includes support for the most common storage arrays that support DM-Multipath. The supported devices can be found in the
file. If your storage array supports DM-Multipath and is not configured by default in this file, you may need to add them to the DM-Multipath configuration file,
. For information on the DM-Multipath configuration file, see Chapter 4, The DM-Multipath Configuration File
Some storage arrays require special handling of I/O errors and path switching. These require separate hardware handler kernel modules.
