5.2. Criteria for disabling multipathing on certain devices

Device exclusion from multipathing uses criteria such as, WWID, device name, type, property, or protocol, evaluated in priority order with exception lists taking precedence.

You can disable multipathing on devices by any of the following criteria:

For every device, DM Multipath evaluates these criteria in the following order:

If a device turns out to be disabled by any of the mentioned criteria, DM Multipath excludes it from handling by multipathd, and does not evaluate the later criteria. For each criteria, the exception list takes precedence over the list of disabled devices, if a device matches both.
