1.2. Storage Array Support

1.2. Storage Array Support

By default, DM-Multipath includes support for the most common storage arrays that support DM-Multipath. The supported devices can be found in the multipath.conf.defaults 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, multipath.conf. 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.
