SUMMARY = "The upstream project used to drive the Device Mapper multipathing driver"

DESCRIPTION = "It provides tools to manage multipath devices \
by instructing the device-mapper kernel module what to do. These \
tools include: \
1. multipath - Scan the system for multipath devices and assemble them.\
2. multipathd - Detects when paths fail and execs multipath to update \
things.\
3. mpathpersist - Persistent reservation management feature allows \
cluster management software to manage persistent reservation through \
mpath device. It processes management requests from callers and hides \
the management task details. It also handles persistent reservation \
management of data path life cycle and state changes.\
4. kpartx - This tool, derived from util-linux's partx, reads partition \
tables on specified device and create device maps over partitions \
segments detected. It is called from hotplug upon device maps creation \
and deletion"
