Support for Linux Device Mapper Multipathing

You can use Linux Device Mapper Multipathing (DM-Multipath) to provide I/O failover and path load sharing for multipathed block devices.

The software module for DM-Multipath is included in the standard Red Hat Enterprise Linux and SUSE Linux Enterprise Server distributions. You should install additional user space packages as part of the setup process.

For information on setting up DM-Multipath, see section DM-Multipath configuration.
