+This utility is used to manage SCSI persistent reservations on Device Mapper
+Multipath devices. To be able to use this functionality, the \fIreservation_key\fR
+attribute must be defined in the \fI/etc/multipath.conf\fR file. Otherwise the
+\fBmultipathd\fR daemon will not check for persistent reservation for newly
+discovered paths or reinstated paths.
