Multipath I/O is available on all of the processor platforms that are supported by SUSE Linux Enterprise Server. The following storage subsystems have been tested with SUSE Linux Enterprise Server:

Most other vendors’ storage subsystems should also work. Consult your vendor’s documentation for guidance.

The multipath -t command shows an internal table of storage subsystems that require special handling. It is not an exhaustive list of supported storage subsystems. It lists only those arrays that require special handling and that the multipath-tools developers had access to during the tool development. Arrays with true active/active multipath support do not require special handling, so they are not listed here. A listing in the table does not necessarily mean that SUSE Linux Enterprise Server was tested on that specific hardware.

Some hardware might require manual configuration in the /etc/multipath.conf file in order for multipathing to work. For information about manual configuration, see Section 5.7, “Adding Support for the Storage Subsystem to /etc/multipath.conf ”.

Storage subsystems that require special commands on failover from one path to the other or that require special nonstandard error handling might require more extensive support. Therefore, the Device Mapper tool has hooks for hardware handlers. For example, one such handler for the EMC CLARiiON CX family of arrays is already provided. Consult the hardware vendor’s documentation to determine if its hardware handler must be installed for Device Mapper.
