man multipathd (Administration système) - multipath daemon
NAME
multipathd - multipath daemon
SYNOPSYS
multipathd
This daemon is in charge of checking for failed paths. When this happens, it will reconfigure the multipath map the path belongs to, so that this map regain its maximum performance and redundancy.
This daemon executes the external multipath config tool when events occur. In turn, the multipath tool signals the multipathd daemon it is done with devmap reconfiguration, so that it can refresh its failed path list.
