pnmd is a server daemon for the Public Network Management (PNM) module. It is usually started up at system boot time. When it is started, it starts the PNM service.

in.mpathd(1m) does adapter testing and intra-node failover for all IP Network Multipathing (IPMP) groups in the local host.

pnmd keeps track of the local host's IPMP state and facilitates inter-node failover for all IPMP groups.

The following options are supported:

-d

Display debug messages on stderr.

-t tracefile

When used with the -d option, it causes all debug messages to be redirected to tracefile. If tracefile. is omitted, /var/cluster/run/pnmd.log is used.

pnmd is a daemon and has no direct stdin, stdout, or stderr connection to the outside. All diagnostic messages are logged through syslog(3c).

pnmd must be run in super-user mode.

Due to the volume of debug messages generated, do not use the -t option for an extended period of time.

pnmd is started by the pnm startup script. It is started under the Process Monitoring Facility daemon pmfd. As such, if pnmd is killed by a signal, it is automatically restarted by pmfd.

The SIGTERM signal can be used to kill pnmd gracefully. Other signals should not be used to kill the daemon.
